Boarding was a complete mess. The whole system went down. People got wrong seat for the first half an hour.

Boarding was a complete mess. The whole system went down. People got wrong seat for the first half an hour.

First time flying business class. Very comfortable for our long flight to Europe.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

Boarding time was delayed in more than two hours. Then another hour on the ground before take off. Wi-fi was not working throughout the flight. Business class in even rows by the window are not so comfortable. And space for feet always feel tight. Had a meeting in New York early the following day with multiple people and had to request a delayed start.

My flight was delayed so bad i missed u it so i just said never mind

Seats could be more comfortable, food was plentiful and good.

It was great. All the crew were professional and nice.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

I will NEVER fly with this clown show airline again. Idiots. All of them. Unprepared. Unfriendly. Miserable employees. NEVER. EVER. AGAIN

Boarding was easy. Provided drinks and snacks. Good aircraft and staff

Flight team was very courteous only complaint wS the boarding process and mandatory bag check

Disaster This is why I stick to delta You get what you pay for

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

After 14 hour delaybwith departure time changed 9 times then announcing the flight was canceled. Another later announcement said the cancelation was in error. Also after paying a higher fare to leave in the afternoon then departing at 4am was not right.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.

late lack information taney changed my sit even after i had checked i. a day prior and had been at airport checked in for 5 hrs. i have medical condition that i need to sit in aisle but changes to window. only apparent at boarding and they had no explanation why they changed my boarding pass and had no other seats. very bizarre, uncaring and disrespectful. Made my trip very challenging I should sue you. will NEVEr fly JB again. Ever. Would have blasted in social media but did not want to disclose my medical disability.

Theres several thing i will like to mention and please share this feedback with JetBlue. I was concerned that the food options were limited. Theres no vegetarian options on the sandwiches that they offer on board. Vegetarian options are limited to only cheese and crackers,. Specially on mid day flights there should be more options offered to people. Second comment is that during the flight I watched TWO movies without audio, I tried a few ear sets to listen and none of them worked. Its a shame that they were good movies however no audio. Maybe updating the auxiliary cable and making Bluetooth connections on media will be great. Finally, the bathroom on the plane looked like they needed an update, being remodeled or changed. They look dirty however they are not. Maybe changing, replacing some pieces and updating the air filters will be great. This is not an aesthetic recommendation however a necessary one.

No entertainment, no WiFi, not great seats. Crew was good.

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Plane and crew on board were fine. Everything else was terrible.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

Would be great if Frontier can Assign Seats together under one PNR

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.

food not having to pay for it, reclining seat would be nice, more leg room, HEAT!!!!!!!

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

Was left with many other passengers in SJU by frontier airlines due to delay caused by frontier. Worst experience ever and worst airline ever.
