Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

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

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

Delayed so that missed connecting flight. Connecting flight was also delayed on the tarmac but they closed the gate before the rescheduled time.

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Took off over an hour late with multiple mechanical issues. Gate agent in Dallas was lazy and was slow as molasses. Had a line 10 people long. Spirit bad..

The flight was short. However, my bag was delayed and was put on another flight.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

Because our flight from marsh Harbor to Fort Lauderdale was over three hours delayed it caused us to miss our flight in Fort Lauderdale. Because we missed that flight, it cost us nearly $100 apiece for four different travelers which totaled nearly $400. We are seeking a reimbursement for the flight that we missed in Fort Lauderdale Florida.

Flight expected to leave at 6:40 pm ended leaving at 8:00 am the following day. I slept in a cold airport. Never again Spirit for me…

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

This was the return leg of my journey with Spirit Airlines. Despite its reputation, I found no issues as it got me from point A to B safely and without delay, especially with no mechanical delays, which is fantastic in my book! The staff, from ground crew to cabin crew, were all pleasant and hassle-free. The flight was smooth from takeoff to landing. I have absolutely no complaints about this no-frills airline!

I got a one-way, last-minute nonstop flight from PDX to BWI for only $125. Yes, I got nicked $79 more for a checked suitcase and $89 more for the BIG SEAT option, but it was worth it, even with $4.50 for coffee and $10 for a snack (the latter no different than any other airline). The grand total was still less flying on any other airline.

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

This recognisable no-frills airline gets me from point-A to point-B. I was able to get to Chicago without stress. The checked baggage collection and reclaim could be improved.

The crew was the best and very accommodating I know you don't offer any complimentary items but water and coffee will not break the bank !!

My flight was cancelled!!! I had to spend 200.00 on another flight!!

The whole day was a nightmare. Flight extremely late. Boarding was a mess of a nightmare.
