Flixbus is super cheap. The service fees are low and if you book early out enough, you can find some great $4.99 fares. The rides themselves, when adhering to schedule, are pretty pleasant and quick. I've only taken the Sacramento to SF round-trip connection as it makes a stop in Oakland, so my review is reflective of this experience only. In my experience the buses have been cleaner and felt newer than other private transit I've utilized before.
I have taken maybe 50 trips over Flixbux over the past year. I would do the Sac-Oak connection pretty much every weekend. Initially, it was great. Oakland is exactly where I need to be. It's much cheaper than Amtrak, less sketchy than Greyhound, and saves me a BART/Uber to/from the City as I would have to with Megabus. Seemed like an all-around great deal. And for the first 9 months or so, the service was great. Yes, there would be delays here and there, but typically no more than 30 minutes. (For reference, Megabus which seems most similar in service and price to Flixbus, is almost never delayed. I've taken Megabus about 30 times and only had trips that were delayed a handful of times).
A few months ago, I noticed the delays were becoming longer and longer. The longest I'd stuck it out was 1.5 hours. Unfortunately, Flixbus's customer service phone number is pretty much nonexistent. They keep you on hold forever, or tell you there are no agents available to help. So if your bus doesn't show up and you want to know where it is, you're out of luck.
They do have a bus tracker which in theory is a fantastic idea in terms of figuring out where your bus is geographically at a certain point in time, but it almost never works. I think I've only seen it work for maybe 5 out of the ~50 trips I've taken. And I even have the app. This to me, is the biggest downside to Flixbus's service: the uncertainty. The feeling of standing alone with your luggage on a random sidewalk (not even a proper station with employees you can direct questions to), and wondering "Will my bus be here in 3 minutes or 3 hours?). If they could just be transparent about delays, I could occupy my time with something else. I could go grab a meal or go back home briefly so I don't have to wait in the cold (or worse, the 110° Sacramento summers). But they aren't. Often, you won't get a text or email about delays. You have to go on the app or mobile site yourself and check, and often it's only updated AFTER the scheduled departure time. So what's the point?
This is problematic for multiple reasons. You aren't just wasting your money on your fare. You're spending additional money to get to your destination another way (for me, it's usually Amtrak which is the most expensive option because I can't just NOT get home for the night). You're wasting your time waiting at a bus stop for a bus that may never come.
They do technically have a refund policy that you can contact via email form on their website, but only for delays over 120 minutes. If you're waiting for an hour and a half, you're outta luck. I've submitted about 10 claims at this point, but only have ever gotten ONE successful refund, ever. And it took about 30 business days to get that response--that's not a typo. 30 BUSINESS DAYS.
For these reasons, I cannot in good conscience recommend Flixbus as a company. If you are broke and this is the only method of transportation you can afford for longer distances, then okay, maybe you can risk the delays. If your money is more valuable than your time--sure, give them a shot.
But if you require reliability in a transportation service, or don't want to waste your time, or would prefer not to wait in the dark streets of West Oakland for 2 hours with no updates from the app and no way to contact customer service, then absolutely, 100% stay away from Flixbus. You have other options that do have their own advantages and disadvantages (my preference is Megabus, Amtrak, and Greyhound in that order) but at least one thing they all have in common is that their vehicles show up and get you to your destination relatively on time. And at least if Amtrak or Greyhound are delayed, you have a station with food, bathrooms, and employees around to service you, rather than being stranded in alone in a dark street with no notification or direction.
EDIT: in response to Daniel's suggestion in his Yelp comment that I contact Flixbus via Facebook or Twitter, here are the standard responses, verbatim, I've received from both platforms:
"please fill out this form and reply to any email you receive so your case will be handled by the relevant department"
"The form is the only way to contact the refund department."
- radio silence - I last contacted them 10/28/2019 and still haven't heard back lol
So, not only is Daniel's solution fake helpful, but it actually wastes more of your time. Never encountered such a negligent customer care team before. read more
