Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Delayed departure. Delayed after landing pulling into gate. Delay due to sky bridge malfunction

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

I had back trouble prior to my flight and everyone was great about helping me.

Jetblue needs to improve on Onboarding as it seems to always be behind on departing. It never leaves on time. I would recommend to have an earlier Onboarding in order to leave on time and respect your customers time as well.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Too many fees (but that seems to apply to all airlines nowadays)

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

Seats are way too snug for my hip to knee ratio and the recline on the seat in front of me made my experience worst. My legs had no room at all. Not a plane for people 6 ft or over unless you fly first class.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

I didn't get to do this flight l, hard to review

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Left Denver late, then sat on tarmac 30 min after arrival

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.

Bought seats on the flight and they were supposed to be 2 and a jumpseat. Plane clearly changed and it was a regular 3 seat row. Asked for a refund and was denied. If I wanted to sit next to someone else I wouldn't have bought the seats..

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

It’s a cheap airline and I wish if they had better seats.

Seats are cramped and uncomfortable. You have to pay for everything and it is very expensive.

For a busy travel season, everything was clearly marked, correct, and smooth. My favorite travel description is “UNEVENTFUL,” and this trip met the mark!

The flight and crew were fine. When we (several groups) arrived in Norfolk on Sunday we discovered our bags had not arrived. The staff at norfolk airport was less than helpful. Told us our bags wouldn't arrive until Thursday. When asked what happened they said it bags never made it on the plane and it happened all the time. When asked about reimbursement for replacement items the desk agent said we could try to submit receipts online, but they weren't sure we would be reimbursed. I understand this is a low cost airline, but this was really beyond poor customer service.
