Long layover between flights to Long Island from BWI - need better coordination between flights

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

An entire day of delays. Cost lots of money. Meals and a hotel.

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Pretty seamless, just a tad bit late in taking off and landing.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

Near 4 hour flight with only 1 service. Had to use call button to request water. Internet and power not working until into flight. Internet would stop working during flight.

My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.

If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.

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.

No included food for a 5 hour flight and the entertainment was only accessible if you had wired headphones (not provided). Otherwise though, great and smooth flying and customer service.

Friendly crew, efficient boarding and flight arrived early. Couldn’t ask for a better experience

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

Good. No issues except a slight delay. Crew came in late.

The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

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.

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

Flight got delayed for 5 hours no good explanation was offered ;(

There was no one at the counter to assist with our check in. The app didn’t work, so I arrived at the airport with time to check in and I couldn’t because no employees were there. When I finally got someone on the phone, it was inside the 60min rule and they said I could no longer check in and they could sell me another ticket. We had to scramble and pay an additional $800 for tickets and THEN AFTER (about 60 min from my original convo with customer service and 10min after original departure time) I had boarded my new flight, there was email saying my original flight from Frontier was delayed and leaving 2hr 50min later, but I STILL wouldn’t have been able to check in. Which means customer service should have been able to see it and let me check in because I was well within my check in time. When I call Frontier, they hang up on me. So their app didn’t work and they employees left and they take zero responsibility or assistance with their “customer service”

Everyone seemed to be in zone 1 for boarding. Maybe break it up a little. Otherwise, smooth flight.

The experience was good. No frills but I got there safe and sound and on time.

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.

After boarding and un-boarding twice over 6+hours, the flight was canceled.
