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!

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

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

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

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.

Terrible. Delta delays caused us to miss our flight and they did nothing to fix it.

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

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

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

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

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.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

Paid WiFi was only available for a few minutes. Avoid at all costs.
