Missed a flight had to wait an additional 4 hours plus for the next flight. The issue was under staffing at the airport itself as well as at the United Terminal. The white line before even getting up to the security screening was over 20 minutes long and the security screening itself would have been another 20 minutes so there's definitely staffing issues overall for the airport itself. As for the United Airlines terminal independently no sense of urgency to try to get a customer onto a plane before the flight leaves 30 minutes prior to departure. In general you'll pay up to $30 for parking if you park over an hour in the lot which of course is not United's fault and instead is the Ontario airport overcharging for parking. There's construction on the main entrance street going to the airport so expect to be late. You can't go around the backside of the airport to try to avoid it but All in all pretty poor experience in comparison to the 5 other airports within an hour plus drive. The United Terminal itself pre departure gets a lot of announcements some verbally some over the intercom so you'll have to get close enough to hear the verbals. Hello this is Steve Hello OK 0 oh OK I head out front and look for you then Alright see you in a minute Bye bye read more

I had a layover in San Francisco that was delayed landing time due to construction at the airport. it was looking like I was gonna miss my connecting flight, but I was assured by four different United employees that United was communicating with each other and that they would be holding the plane for the four of us that needed to board. When I exited the plane, it was a 15 minute walk and me, a 63-year-old woman, had to sprint as fast as I could through that airport. Only to arrive at my gate to a closed door and they didn't even have an agent out there to help us rebook or offer any kind of compensation or even say hey sorry we didn't keep the doors open like we said we would. They were loading my bags onto that plane at the same time. I was arriving at the gate and they would not lend me on that plane left me sitting for an additional seven hours. I will never give a dime of my money to that airline again read more

My first time flying United last Friday from Terminal 2 in Ontario,CA; layover in Denver, connecting flight to Hartford, CT. Online check in with the app 24 hrs in advance which was easy especially since we only had carry-ons and no checked luggage. No delays, smooth boarding, even conveniently departed from the same gate as we landed in Denver. We did have to check in our carryons at the Denver gate because they ran out of overhead bin space but that was also a smooth process. It was a newer plane with screens on the back of each seat. I watched Jurassic World Rebirth on the flight from Denver. Overall a decent flying experience. read more

I had the best experience in there. Great staff, great food, and great flight attendants. Smooth ride too.

Located at Terminal 2 of Ontario International Airport, the counter of United Airlines wasn't open yet. It was exactly 2 hours before my flight, but there were other people waiting with me, so I wasn't too worried. The young, energetic man who powered on the kiosks was very helpful and knowledgeable. I didn't have a California ID, so I wasn't able to access the kiosk in that way. Using a credit card worked! Haha! My boarding passes and baggage tag were printed, and I went on my way to at TSA upstairs... The escalators opened at 3:30am. See you later! read more

Worst airline experience I've ever had with Delta Air Lines. From the ground to the air, the service was consistently terrible. The staff at the airport were unfriendly and unhelpful, showing very little respect or patience toward passengers. What made it even worse was seeing crew members talking loudly in the waiting area during rest times, which felt completely unprofessional. The in-flight experience didn't improve at all. The food was honestly awful -- poor quality and not something you would expect from a major airline. But the most disappointing part of all was how they handled my damaged luggage. My suitcases were broken during the trip, and despite reporting it properly, I never received any compensation. The whole process was disorganized and frustrating. This wasn't just a bad experience -- it was beyond unacceptable. Definitely worse than anything I've experienced before when flying. I would strongly recommend avoiding this airline if you expect even basic customer service. read more

They now have a policy that states you must enter payment information in order to check in for your flight. You can't go on the trip that you already paid for unless you provide card information. I booked with Expedia, but I won't make that mistake again. I don't want airlines charging me automatically for anything or anyone that is in my group. read more

It was my first time using United airlines and will be the last. I went as far as getting the United Airlines Credit Card, in going to cancel that card. The worst experience ever, not even Spirit or Frontier Airlines are this bad . Save your money and fly another airline. read more

Nine of us booked a flight to celebrate a birthday in Nashville out of Ontario, California. The plane had a technical problem and was delayed too, and then four hours which caused a conflict with our connecting flight out of Houston to Nashville and United could not book us any other flights to get to Nashville... the agent at the counter suggested we try other airlines which we did an American Airlines was very accommodating... Now trying to get a refund from United. They basically have told us to go pound sand for something that was clearly their mistake. They charged us $1200 for a non-service. I will never fly United again they suck and I have flown them before. read more

Fly DELTA OR ANY OTHER airline besides shitty ass United. They are just the worst out there! No customer service and in it for the money! read more

If I could I would give this airline a zero stars 3 and a half hour wait time on tarmac And all we get is a half ass joke of an apology Now I know why governor's want to fine them and make them pay I would never recommend this shitty airline Did I mention fuck this airline they care nothing about the people that keep it in business Outdated equipment don't get me started Smoke alarms going off for 3 hours and still refused to let us off the plane Just an all around shitshow of big business not caring about customers read more

So I was booked for a flight to Denver! At 5:24am I get here in time to get on the plan and get in line to check in my bag! But because the line was so long they cut off a1/2hour before the flight! So a few of us that where still in line got fucked over and miss our flight! And I was here 45mins in advance! So the lady put me on a later flight! Grate! But then she got a call saying that they were still fueling the flight I was supposed to be on? And it will be delayed a little! So I asked can I still get on! She got up set and said NO! I HATE FLYING! At this point I will get there faster driving! And united sucks ass! It's because of y'all why people have stopped flying in the first place! To many rules and bull shit because you can be a ass! I hope y'all go out of business soon! And any airline that's the same way! Down with y'all! I'm a very unsatisfied customer! read more

Their service and gate agent did not have all the info for them to coordinate my standby request. I show up early to check my bag. The check-in agent offered to put me on an earlier flight. The flight was empty due to a 6 hr delay and most people already left. The United booking system did not flag my reservation so the agent proceeds to put my bag on an earlier flight. I tried to reconfirm at the gate, agent there assured me it was fine because she had a conversation about me with the agent downstairs and the flight was empty. Then when I tried to get on the plane, I was turned away by the person scanning my boarding pass. What kind of messed up system or process do they have at United that I was able to confirm that I will get on with 2 prior agents for the standby flight then to be turned away the last minute!! The agent was nice enough to call customer service to see if she can get it corrected. She was not able to due to booking through a third party. If I knew that from the beginning, I would been able to call my travel agent to figure it out. Anyhow, my luggage went to SFO and I had to stay back for my original flight that was 2 hrs later. Never again, United! read more

United and Continental used to offer decent destinations, schedule and aircraft types from Ontario. Unfortunately, they have seriously declined in all aspects over the last few years. Houston and Denver have been thinned out and are only served by crappy regional aircraft without first class. I can no longer catch good connections to Europe or the East Coast. I hate having to drive all the way to LAX to catch a flight, but United is forcing me into it. Update 4/26/16: today I learned that SkyWest is taking over ONT completely and all United employees are being transferred to LAX. This means better aircraft, routes and service with United will not come back for a long time. I could not be more disappointed with United. Time to switch to Delta and give up my 1K. Update 6/14/17: United brought back mainline aircraft on the Denver route with 737-900. Finally it's getting better. More seating capacity and a first class cabin. Bumping UA at ONT up to 2 stars. Update 6/19/19: UA added more flights, including resuming the IAH service, and upsized some planes, like the occasional A320 to SFO. Bumping UA up to 4 stars. On my flight today, we had 2GS and 7 1Ks. A good sign. read more

I have no idea why United Airlines has such horrible reviews. I have flown with them so many times, and we have never encounter rude team members. Sure, a delayed flight here and there, but we always arrive to and from our destinations safety. Isn't that the most important thing. I mean, who cares if the handle of your suitcase gets broken or you don't get a Coke on your flight, you made it to where you are going safely. read more

United Airlines - Airlines Near Me - Ontario, California

The airline consistently under staffs causing significant delays. It has exorbitant additional charges. Worst airline I have ever flown!

United Airlines - A cockroach ewwwww! - Airlines Near Me - Ontario, California

United Airlines is inefficient and non accommodating. The flight changed separating my husband and I to return home on different days and different time. The lady and guy in white at the counter blamed us for the flight change; very stupid. It's not the customs fault for flights delays or cancelations. I will NOT be flying United Airlines ever again. read more

Worse customer service. No assistance when missing flight due to their delayed flight. Absolutely no concern to make their poor service right. Gave a ticket to catch a bust since didn't have another flight for 5 hrs and ticket was wrong. There was no trip from San Francisco to Sacramento as ticket had shown. When it was pointed out ticket was wrong they just said sorry. read more

Be aware , that if your flight leaves at 5am no one is at the desk that early to check your bags 2 hours prior to your flight ,I know ONT is small but they should have some one there . on the way back we waited for our luggage at least 40 minutes to be put on the conveyor belt , and somewhere along my flight someone broke into my suitcase I always have a TSA approved lock they have opened without incident .What made me mad is the completely broke the one zipper off and the back side of it was by inside my suitcase and the dangle part was still on the lock ! They lost me as a costumer! read more

Use any other airlines, every single week that I take United there's a delay, southwest way better option and less money. Was trapped inside a plane for 2 hours without moving read more

so hubby decided to try United since Ontario airport is closer to home instead of getting direct flight from LAX.to Hawaii from LAX like we usually do. Big mistake . Our connection flight got delay for 3 hrs so that mean our other flight will leave without us in SanFrancisco Sad part we didn't save any money or time by going with United infact we missed a day of our vacation sine the connection is so late that by the time we flew into San Francisco there would be no more planes flew out to Hawaii for that day. We ended up have to drive to LAX early the next day anyway to catch the direct flight to Hawaii Lesson learned , no more flying with United if we can help it and especially if there is any connection flight them definitely a BIG NO Hawaiian Airline all the way from now on read more

The middle-age heavyset man behind the United check-in counter this morning does not even deserve one star. His attitude is as if we were a burden to him. No greetings and simply curt and short questions. He seemed to want us to move along without bothering him with questions. One of the two questions I asked was whether I can walk my mother into the gate, which many airports allow with appropriate identifications. He simply said no and turned away. The other gentlemen who was helping other customers at the adjacent United kiosks saw what happened and quickly came to us and offered wheelchair assistance to assist her to the security/boarding gates while we were walking away. He quietly mentioned that the guy at the counter is hired by EUG and doesn't know how to enter the code to print me a ticket to assist my mom through the security gate. The ONT airport is great in that it does not have high traffic but it's not uncommon that United changes gates or have delayed flights. read more

Please don't make any reservations with United Airlines! I paid for the insurance! Covid that is uncontrollable, are cruise was cancelled! They refuse to refund!! 6 months in advance they refuse! Thank you for a voucher that I can't use! You also received stimulus money???? Never will I ever use your service again! Rip off what was the insurance for?????? read more

We had a terrible experience with United Airlines. Our flight was scheduled for 5:45 am, and we arrived at the airport on time. However, the check-in process was unusually slow, taking much longer than expected. After finally getting through check-in, we proceeded to security, but we were stopped by the employee who checked us in. They realized there was an issue with my boarding pass and spent another 15 minutes verifying it. Once we reached security, we encountered another problem: the TSA agent noticed a discrepancy between my boarding pass and passport. This required us to go back to the check-in counter, where it took them another 10 minutes to identify that my birthdate was entered incorrectly. By the time everything was sorted out and we returned to the security checkpoint, there was a lengthy queue. Despite rushing through security, we arrived at the gate just 5 minutes late, only to be informed that we had missed our boarding window. The airline staff instructed us to reschedule our flight due to the delay caused by these issues. Which where all cause by United Airlines. read more

TIP= To Insure Promptness. I believe always TIPPING service people is basic courtesy.

I want to give a shout out to the flight attendants on flight 955 from Tel Aviv on Friday, November 1, 2019. Although the flight was delayed due to unforeseen circumstances, the staff was very accommodating to those of us on the flight. Ken was extremely kind with a wonderful personality. He was a pleasure to talk with. All of the flight attendants were nice. When we departed our flight Ken said good bye to us by name. Thank you Ken and all of the flight attendants for making the 15 hour + 1 1/2 hour delay flight such a pleasure. read more

This the third time in a roll my flight was delayed to SFO. The United staff wasn't any help at all. They would tell you whatever to get you to leave the counter. Again ONT airport working with United is not good at all. United stall is lazy and don't if you make the not flight or not. It room me three times to learn not to fly out ONT airport their will not be a four time. I'm honestly thinking of not flying with United as well as they really don't care about you a paying passenger and weather you make it to your final destination. Again don't fly out ONT with United it's no good. read more

Great customer service. Very clean! I was running late, n they waited for me. I was last person to get on plane. They offer drinks, n snacks. Stewardess was really friendly. read more

I tried using United airlines several times already. Early morning today I booked for two traveling from ONT, CA airport to Saginaw, MI. Round trip for $449 each I paid the reservation by PayPal just to find out that the return destination was change to Orange County airport. I called United this afternoon in the hope of changing my return destination back to ONT. now they are charging me an additional $121.00each. I tried to explain to them that when I book my flight originally was only for $449. I don't think it's fair to pay an extra $121.00 for their mistake read more

I am hoping that this Yelp is monitored by someone who actually will reply or contact me with an effort to resolve this horrible experience. Screenshots show texts of delayed flights, clear to the next day! I along with two friends had to call out from work. We were not offered any explanation, we were literally offered water and cookies. No meal, no hotel accommodations. We were moved along without regard. Our bags were lost, then found after a 3 hour wait to reclaim them. Our finally flight at 2pm finally was cleared to fly. We were 3 of the only passengers on the plane. It was by far the worst experience! Each of us are voicing the issue and I've opted to share this horrible experience and lack of empathy or regard of our situation. Booo United read more

Very unhappy of the treatment we received at LAX from the UNITED STAFF.... They were all so rude and couldn't be bothered by any questions. It was a awful way to start our vacation we were so excited for. The only person that was kind and you could see his smile through the mask was the gentleman that took our luggage when we handed it in. WISH I WOULD HAVE GOTTEN HIS NAME OFF OF BADGE. The rest of employees should take note from this gentleman. WE should all be grateful for employment and CLEARYLY the United staff is NOT! read more

If they brake you're luggage and you ask for a replacement i suggest you do it within 14 days after you report it witch was what they did not inform me about so I'm left with my damage property they did, ppl don't have time to go back to the hell you put us thru traveling so what makes u think we wanna go back again read more

On this leg of the flight from George Bush International in Houston to Ontario International in Ca, we got great service. They came around twice for drink service and checked to see if we wanted snacks. They came around another two times with coffee for everyone and even one last time for water. We were able to book our seats online early enough and I had done this far enough in advance that I got Economy plus seats for no extra charge. I had just flown the Detroit to the Houston route, United as well and its almost the same flight time and had none of the same service. Well done! read more

United Airlines - It's a check in gate for your check ins. - Airlines Near Me - Ontario, California

1) If you read my other reviews, you can see that I'm a very forgiving and flexible person. ALL my reviews have been 5 stars (enough said)!! So would like to emphasize that this is my absolute first review that is BELOW 5 stars. It's NOT 4 stars, NOT 3 stars, NOT even 2 stars, but it's a justified 1 star. 2) It starts off with the proverbial bait-and-switch strategy... Offer the cheapest airline tickets possible but fee-the-heck out of every possible thing the VPs can think of. Fair enough. This alone will not warrant a 1 star review. I think I'm not alone when I say that I'm pretty jaded when it comes to fees. It's almost what you expect. Now-a-days it's the opposite. When you don't get fee'd it's like "whoa, you mean that's free?!!!!" Badamn! 3) This is the FIRST EVER airline that I have reserved seats online (which I have confirmed, btw, by logging on and checking my seats the following day) only for them to remove my seats reservations days before our flight. This left my scrambling to try to get my family of 4 (2 kids in-tow) to somehow sit together. We ended up going with Plan B (my wife and I played man-to-man. I took my 7 year-old son at aisle 24, while my wife took my 9 year-old daughter at 30-something aisle. down to 4 stars. 4) On the day of the flight, we checked in online (so we were able to print our boarding passes), but when we got to the airport, we had to go to the UA kiosks again to check-in???! I'm like what the???! If you have to check-in again at the airport, it defeats the purpose of checking in online, at home. down to 3 stars 5) When you finally make it on to the gate and it's time to board, UA came up with two lines. Totally confusing and counter-intuitive. Okay, there's the possibility that I'm the only dumb a## to not get it (fair enough), but how would you explain the moaning and groaning of countless people with eyes rolling as they were trying to explain the boarding process. Their process is not intuitive at all, that they had to announce and explain it 4 times!!! I would hate to be a foreigner who doesn't know how to speak any English. down to 2 stars. 6) It's almost an unsaid standard that all planes should have some sort of monitor (if not individually, at least a big one that a group can view/share. but our plane had zero monitors. Now-a-days, that's completely unacceptable. down to 1 star. If your goal is to feel like a 4th class passenger (not 3rd class, not 2nd class, definitely NOT 1st class), then fly United Airlines. You won't feel disappointed. You'll feel 4th class all the way. The funny thing is... if UA Executives thought that "an experience like this will make them want to fly UA again, BUT the next time upgrade to business class!" they're sadly mistaken. This experience has not only scarred me, but it has permanently damaged the UA brand. I'll now be telling family and friends to avoid United Airlines (at all costs)---Great Job, UA Executives!!! **I'm the type of person who tries to save as much as possible when it comes to flights (heck, I even flew China Airlines despite the negative reviews--see my review). But my experience with UA is so bad, that I even took the time to write this review. Please do yourself and your family a favor... pay $10 more per flight and feel like 3rd class. The 3rd Class feeling is leaps and bounds better than the cattle-like 4th class experience with UA. Peace. read more

This airport is not busy at all! No lines at TSA, it took us 5 minutes to get through the checkpoint. Unlike larger airports you will not find many shops and restaurants here but if you are going on a short domestic trip this is the airport to fly from. It's actually not that small, they won't roll up a ladder to the aircraft like Long Beach Airport. United is really affordable and if you use your Citibank thank you points to fly, you will get 60% more value on your points. For example 100 points is equivalent 160 points when you fly with United. For a 1 hour flight there's really not much you can screw up on. read more

I was told that the refund assurance only covered if you cancelled 24 HOURS AFTER THE PURCHASE!!!! WTF?!?!?!

I want to make a COMPLAINT! I am only giving 1 star because ZERIis not optional. I will also be writing on Yelp and any other review site I can search! My son is in the Army and was leaving for Korea this morning. Anytime he travels with #AmericanAirlines they check the entire family in so we can sit with him until he boards the plane. #UnitedAirline staff in Ontario CA was so RUDE was only going to allow 1 family member to be checked in and the others would wait in the car. Even after pleading with the staff we were still denied access back. This is how we treat our Military and their families?? Knowing they will be separated for months to years at a time. We will NEVER travel United Airlines again!! American Airline moved my son to 1st class and fed him an amazing meal even on a short flight. United airlines is TRASH!!! read more
