Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Onboard functioning wide-variety entertainment on a budget and having an open pantry is nice. Seats are not comfortable but go provide plenty of legroom for a 6'2" 260lbs man.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

Worst customer service ever experienced on the planet, dirty plane, no communication, and severe delays

Flight cancelled 2 hours prior to boarding. No explanation. No refunds.

Delayed by 1.5 hours. Terrible apologies, half hearted at best. It will be a LONG time until i book w Jet Blue again. Very disappointed.

My check in was stressful. I somehow lost my seat from my original booking, the plane showed no availability/no seat when it was time to check-in. I called and was instructed to try to get a seat at the airport. I asked if it was a full flight and the travel agent said the site showed some seating but was not able to secure one for me. Why not? On my way to the airport the app finally revealed one available seat towards the back of the aircraft that I was able to book. It ended up being an overbooked flight, so glad I wasn't stuck.

Flights with JetBlue from San Diego to Boston are a miserable experience. The flight was delayed about 1.5 hours due to “weather” supposedly but the flights for other airlines left on time so it just have been some kind of weather that only affects JetBlue. I had a small carry on - purse. The crew stored it in a bin 2 rows down from me because they were using the bin next to my seat for other people’s stuff. The TV screen in the emergency row seats does not work. It just was awful from start to finish. When we landed, we had to sit inside the plane for a very long time because the plane had to be moved to a different gate.

They made me check my bag and I didn't need to as there was overhead space available. I paid for a seat towards the front of the plane and it didn't recline. I requested a refund and they declined to give me one.

I have to congratulate Kayak (and Dylan the Chatdeal agent) because because when we decided extended our trip in Florida by two days, there were many direct flights oprions back to Boston available on the Friday we wanted to fly on the JetBlue website, but once I canceled the original JetBlue flight on their website, those direct return options disappeared immediatley! I think it's a game JetBlue plays. . Luckily, I checked Kayak and they had a direct flight that wasn't appearing on JetBlue's website and so I booked it, and we were able to fly home direct through the Kayak booking when JetBlue was offering nothing (even though I have been a True Blue member for 20 years, and also am a Mosaic member). So much for loyalty- their algorithm for booking is like a shell game. JetBlue used to be a good company but now they're worse than anyone. Also I was originally booked this trip to Florida, two months before the departure date, I booked the trip on JetBlue's website and then after the payment part, they said there was a problem and that I needed to do the booking again, so when I immediately went to rebook , the price had gone up 30%! I called them and it sounded like they had heard this so many times before and the guy told me to check back in 10 minutes and the price would be back to where it was when I was booking- it but it never was. How could the price go up 30% in one minute two months before the flight???? They're playing a game with their customers. Anyways, I booked a cheaper flight then at a less convenient time. So fast forward two months the night before the 7 AM flight, they sent me an email at midnight when I was sleeping to let me know that my flight at 7 AM had been canceled. The only thing they offered was a flight that night from from a different airport (Providence) to a different airport in Florida (West Palm Beach) or a flight two days later. No compensation, nothing. They couldn't of tried to get another plane to the Boston airport? They had all night to do it. I passed on their ridiculous options and flew with Delta and it was a great experience. Of course, I had to pay a lot more booking on the same day, but JetBlue doesn't care. I put in a lengthy complaint with the agent who assured me someone would get back to me by email within three days and I haven't heard a thing. JetBlue used to be a good company but now they're among the worst. The only thing they still have is decent legroom, but the corporate bean counters will probably start taking that away too.

We were made to wait in the airport for six hours for a flight that was ultimately canceled.
