Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

The flight was 6 hr late and then they blamed it on the weather. All of the other planes were coming and going fine.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

The flight attended didn't ask one everyone in our party if they wanted a drink or snack. The one attended appeared to hate her job which is the one that attended to us.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

Flight was changed last min. Had a screaming infant a row in front of me and a parent who did nothing to calm the child.

Kayak does not know that spirit airlines charged me $70 to fly. But the bag check-in was $89 each way. This is false advertising to lure people. Spirit airlines sends bunch of emails after flight purchases to buy wifi, better seats, priority boarding, secure reserved seats. This is false advertising. Up front pricing. I would of flown jet blue or Alaska airlines.

Every interaction the airline seems to want to find a different way to extract more money from you. The second leg of our journey they wouldn't let us board the plane without taking another $99 for a bag we asked about at the ticket counter and boarded with on the first leg of our journey. Horrible airline, poor culture. Not flying Spirit again.

Didn’t make the connecting flight due to a delay on our first flight.

I felt scam to have to pay $50 additional for my carry on luggage which was free for my other airline.

No basic services such as water, snacks. Internet very expensive. Seats were very small, hard and uncomfortable. Alaskan Airlines, my outbound flight to Boise from Orlando, offered beverage service, a snack, and reasonable priced internet, for the same price as my return trip on Spirit. It had more comfortable seating also.

Awful experience. Both flights were delayed several times with weather but also crew members being the official cause. The vouchers are unusable and insufficient ($50 voucher to fly the same crappy airline is a joke for putting me on a red-eye that landed at 3:00 am). The aircrafts were old and uncomfortable (have a real pocket on the seat, for crying out loud!).

The staff at the counter were very rude and unprofessional

Lower price not worth it. Delayed missed connection. Would have taken 24 hours to get to Atlanta. No takes your vouchers making them useless. Never again.

Horrible. Delay after delay. People yelling and making obseen gestures!

Overall good for being my first time flying with spirit
