Never travel with Frontier Airlines. (Long post)
On November 23, 2025 I had the worst travel experience I have ever had in my entire life. My family and I booked a trip home for the Thanksgiving holiday. This is the first Thanksgiving we'd be going home to Denver in 4 years. We arrived at the airport at 5am for my 6:45am flight. We spent 25+ minutes in line to be helped by a ticket agent because all the kiosks were down (we are charged $25 for agent assistance by the way). Weighed our luggage personally and confirmed it was 40.02 lbs. Once the agent weighed it, they said the luggage was 53 lbs and charged us $125 for the overage fee.
While making our way through TSA another 45 minutes (traveling with 3 children ages 14, 6 and 3 which will be important later), I got a text that our gate changed and instead of terminal A, we would be departing out of terminal D which is about a 10 minute train ride away. After catering up my kids and running to the train, we got to the gate at exactly 6:25am. While running with the stroller, I watched the gate agent close the doors as boarding ended at 6:25am (exactly 20 minutes before the flight). I asked if she could please let us on to which she responded "I am actually too busy, I can't help you. I need to work another flight so you need to return to the ticket counter to be rebooked." and walked away.
I make my way back on the train back to terminal A, outside and back to the ticket counter. The ticket agent let me know the next flight to Dever would be the next day 11/24, or we could catch a flight from Houston to Phoenix at 12:13pm, have a 2 hour layover then fly from Phoenix to Denver arriving. Reluctantly I agreed because I did not want to spend 24 hours in the airport with 3 children.
After going back through TSA for the 2nd time, and getting back to D terminal I looked at the flight information and they had all 5 of us sitting in separate seats. Because my youngest children are 3 and 6, they absolutely cannot sit separately. I called customer service and talked to different representatives for about 3 hours who eventually told me there was a non-stop direct flight to Denver, leaving at 11:48am and there were plenty of seats so we would absolutely be able to sit together. They processed the change however I wasn't able to access the boarding passes. The gate agent told me they couldn't help me, that I need to go back to the ticket counter again.
I got back on the train, went back to the ticket counter again and the agent confirmed the flight was changed but we had no seats. And if I wanted to change it again, I would have to pay $1400 for the flight difference. They eventually gave me boarding passes, and sent me back through TSA for the 3rd time. We had 11 minutes to get to the gate before the door closed again! Thank goodness the flight was delayed by 30 minutes which gave us time.
I called Frontier today and spoke with Aman Kothiyal who let me know the most he could do was offer a $75 voucher for a future flight booked within 90 days. Imagine being charged extra, being told I am too busy, I can't help you, navigating through TSA 3 times with 3 children just to be offered a $75 voucher for a future flight... Disappointed in not even the word. read more
