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, the flight attendants were very friendly and the food was also good.

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Seats were very comfortable. Crew were excellent. Food very good.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

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

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

The CX617 from HK to BKK was delayed more than 1.5 hours.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

It was a good flight. Of course it was full, but it went well.

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

They took a horrible route with a lot of turbulence and I eneded up getting sick. Even if the flight takes longer. Don't put people life at risk just to get to the airport on time.

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

The crew was great but it felt gross how spirit charges you for every little thing. Picking your seat should be free (first come first served). Beverages and food I get. But picking where I sit? Gross.

Had to board plan 2x due to lack of security check after 1st boarding

Miserable. The crew was rude, the flight was delayed 5 hours for mechanical reasons and then “weather” even though other planes were leaving.

They kept Changing the flight times. It was delayed several times and at one point it was supposed to depart at 3.40am! At which point we ended up staying overnight and booked long a separate United flight for early morning departure. The spirit flight then got moved up and left at 1.30 in the morning when it was supposed to leave at 9.40pm the night before.
