Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

For some reason, I couldn't choose my seat. The airline gave me a seat when I got there. Not happy about that. Otherwise, everything else was great!

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

The food is terrible. The same pasta or chicken with bad taste and presentation

United have really come back. Airport and boarding process is clear and good, app and information also very good

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..

I got sick nothing contagious but distressing and the care I received by Kayla? Keighly the flight attendant will be memorable for ever. Thank You

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

Waaay too small plane. They also need to up the size of the overhead bins. I would love to keep me 3k with of camera equipment in my hard case baggahe instead of it being thrown into the belly of the plane

Attendants were pleasant and the flight was smooth and relaxed.

A little late at the start but all worked out well.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

I liked the humor of the captain and crew on the flight from Flagstaff to Dallas. They were humorous.

AA delayed the flight for 3 hours and 50 minutes, but delayed the last 2 hours, 30 minutes at a time, so if we knew before, could have stayed at home and worked instead of being at the airport wasting time... The plane's crew was excellent, not their fault.

After arriving in Dallas, the aircraft taxied for an unusually long time and was unable to park at the gate, which caused a significant delay and made me miss my connecting flight. I then had to wait in a very long line to be rebooked, and I was told that no hotel or meal accommodations would be provided. What is even more unacceptable is that my luggage was mishandled and has still not been located. My suitcase contains important medications that I urgently need, and I have been unable to access them due to the airline’s mishandling. This situation has caused me considerable stress and inconvenience, and I need this issue to be resolved immediately.

Qatar Airways only had spicy meals on the menu in economy class. You might want to get food in the airport before boarding.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

They have the most inexperienced / rude flight staff I’ve encountered

The experience was really good, the crew members were excellent

Honestly horrible. The plane on the way back was delayed 6 times with no explanation on why. When I asked for a refund or some money back because I had to miss a day of work because of the desk, they told me no. Because of how poorly it was handled I will most likely never take spirit again

I love a flight without turbulence and you guys deliver It’d be nice to have comfier seats and maybe some inflight entertainment and snacks but that’s for Delta

This was my first time on a budget airline and I couldn't even sit down all the way because my knees would embed in the seat in front of me. I'm only 6' tall with a 32" inseam. There's no upside other than y'all are cheap. I'm glad it was only a 2 hour flight. Lesson learned! I get why everybody talks down on budget airlines. The staff was outstanding, the flight went as well as possible, great pilot, great boarding, smooth sailing. Zero chance I'll be back though.

Everything was smoothly and convenient! Just stay in this way!

Cancelled my flight and the earliest that they are willing give me for the next flight which was 3 days later on a weekday. Only accommodation they are willing to give was $30 airline credit that will expire in 1 year

Terrible Airline I will never fly that airline again. Shame on you for recommending them.

Flight was canceled, huge lines to get baggage returned. Most other airlines had delays but not widespread cancellations like Spirit.

Excellent! No complaints! All the staff from the counter to the airplane crew, was just amazing and pleasing to talk to

My baby was crying uncontrollably for the longest time and the entire crew was SO supportive, I’m so appreciative of them. Thank you so much for the support during an exhausting moment. We got very lucky.
