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

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

Compared to our Lufthansa flight out, it was pretty poor. Check-in was a nightmare trying to figure out if it was Lufthansa or United, the Kayak link kept sending us to a dead link with United. Then figuring out which code was United was a mess - it took way too long. On the flight, the seats were uncomfortable, they were out of all wines but red when the flight started, then out of red after the first beverage. The flight attendant said they never get restocked before they turn around to the US, so it happens all the time. The food was so bad we threw it away. For a long flight, it was pretty terrible.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

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.

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

Good- no snacks on a 4+ hour flight is painful but more painful was the lack of WiFi.

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

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.

It was horrible. My plane was delayed until the next day resulting in me losing a day of work. It’s absolutely unacceptable and I won’t be flying with you any more and I will strongly caution others to avoid your airline as well.

When we arrived we lasted 48 minutes to be able to get off the plane without air and the plane turned off more than half of the passengers because after they started to leave they realized that the bridge was defective

Pro: The stuff was great. Friendly, patient and caring. Our seat row was clean. The bath room was clean. Our flights were close to on time. Con: The leg room is too small. No blankets or pillows. No entertainment devices at all. I can’t remember to have a food choice. I would fly again with frontier for short distances.

Great option to American Airlines. Affordable prices when compared to AA. Prices in AA to and from Puerto Rico are like Fly Emirates to Kwait.

The flights were right on time. The issue that was the most difficult was the lack of legroom on the planes
