If you are transiting through Doha and you have a long layover make sure you book the flight through Qatar airways and not using a code share that's a book through American airlines because they will deny you a STPC which is a stopover paid by carrier aka the free hotel. We ended up sleeping on the floor of the airport which kind of sucked but it wasn't the end of the world. Next time I will not make this mistake and I will never book with American airlines again.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

We waited an hour on the runway to get a gate in Orlando

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

Sorry I didn't realize I was writing a review for each leg. Please see my previous review - it applies to the entire flight, not just a single leg.

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

The Delta flight was delayed for maintenance issue. The crew is also delayed and I’ve been there at the same time as I was so it was really outside the hands of crew directly. However, where Delta failed was there was about eight other ways for me to get to my final destination and they did not offer changes beyond the initial one. The flight was delayed five hours when they had to change my connecting flight they had to downgrade my premium class for so far zero compensation and I’m still waiting on the results of a formal complaint. All in all this was the worst experience I’ve had with Delta in quite some time. Carrying the review for my first light over to this one, I was downgraded a class and because of my status I’ve only flown comfort plus or higher in some years I was unaware of things like drink vouchers, or anything like that, as far as I knew drinks were complimentary. The attendant was unnecessarily nasty towards me when I was just asking her to explain how it works and I showed her my first class ticket even though I was in the back of the plane and she was still equally unhelpful and frustrated. I’m not saying that the first class ticket should allow better treatment. I’m saying that I was showing that normally I would’ve had it for free beverage and so I didn’t know what she was talking about, she didn’t need to be so frustrated. Outside of that if the flight was 2 1/2 hours and the snack and beverage options did not become available until the final 30 minutes of the flight when we were on the descent, so any snacks and drinks were quickly rushed away. I do not know if this is common for what main cabin normally experiences but I hope it isn’t because that level of customer service and tending to the needs of the passengers is below what I would call essential.

2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

I chose the seats when booked the flight and paid for them. However after checking in I found we were assigned different seats!

Since they are a budget airline, I wasn’t expecting too much but they did some things well. They were on time, the plane was clean, boarding was fairly straightforward and the staff was cheerful and friendly. The only downside was comfort. The seats were fairly hard and after a 2 hour flight your rear end is not feeling so great. Maybe a little more cushion in the seats, Frontier!

It was horrible. My plane was delayed until the next day resulting in me losing a day of work. It’s absolutely unacceptable and I won’t be flying with you any more and I will strongly caution others to avoid your airline as well.

The personal at boarding are rude and try to steel people with their rule of personal item , really bad experience for us

Horrible my trip was delayed 3 hours, we already have set in the plane and they delayed the flight.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Flying frontier reminded me of flying with my family in the 80’s in all of the worst ways possible. From poor customer service to little to no technology. The plane was dirty old and also stuck in the 80’s. From their seatbelts to not having anywhere to charge our phones the seats and the equipment I wasn’t sure if I was being punked or thrown back in time. Needless to say I don’t see myself flying frontier ever again.

I like that the flight was not overcrowded, and I felt had space to spread out a little more. The flight was smooth for the most part no major turbulence. The crew was pretty good accommodating and professional.. the fellow passengers were cool as well… all good! Snacks always makes things better, but of course there were no snacks.
