There was a loud squeaky sound the whole time we were flying.

There was a loud squeaky sound the whole time we were flying.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

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.

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 really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!

Best Thing flight took less time than programmed, quick entry and exit. Recommended!

Always like Jet Blue! It seems, however, that people are getting bigger & seats are getting smaller! We had a very full flight and I couldn't get an aisle seat like I always do. I wish there were more leg room. People sitting next to me were very nice though so it was fine to disturb them if I needed to use the restroom. Otherwise the flight was fine but a bit long.

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 Palm Springs to Chicago O’Hare was on Time and Palm Springs airport is easier navigate. As our connection was only an approximately 50 minutes, we asked staff for insights for the Chicago airport in terms of transferring into the other terminal from which our flight left, and they were unhelpful. However, the United App was very helpful in terms of notifications and even providing directions. The Chicago to Detroit flight was significantly delayed which we all know does happen. However, there were very few updates or notifications as to why this was happening when we would actually arrive. It took nearly 30 minutes for bags to make it to baggage claim. We arrived nearly 1 hour late on a 40 minute flight.

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

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

We are gluten free, there were not any available complimentary gluten free options.

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.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

They stuck us with multiple extra fees. I will never fly spirit again

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.

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!

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.

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

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.
