Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

My business class seat was inoperable and unable to recline for 10 hour flight.

Purchased through 3rd party vendor which made everything difficult. Unable to check in online. Unable to get flight updates easily, tsa precheck information didn’t carry through, longer time to check in in person. Entertainment looked good but had to purchase conventional headphones to view.

Boarding was fast, easy, and we landed early. The entertainment system was very buggy and kept resetting throughout the flight.

Not having an assigned seat until boarding and then having to check my bag.

Boarding was done extremely poorly, with huge crowds gate loiterers blocking people from boarding, multiple lines of people trying to merge into one line. One of the male flight attendants who was doing drink service was not happy about having to let a passenger back to their seat and was unnecessarily sassy about it. I thought he was pretty entitled and not a great ambassador for JetBlue

Flight emergency landed in Chicago due to “Odor” in back of plane . Had to buy ANOTHER TICKET to get to Boston cash out of my own pocket . Then they would notchange my return flight time without a 400. Charge!!!! Insulting.

I purchased ticket so our daughter ( a minor) can sit next to her mother. No help at gate after kayak insisted that this could be done. She ended sitting by herself

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

we were an hour delayed after boarding and given no reason. Headsets cost money. Also there were openrows with no one setting in them but we were told we were not allowed to swtich.

Flight was smooth, amenities (entertainment options and power outlets) were good, sears decent)

Terrible. There was a lot of misleading information regarding ticketing, seat upgrades, & boarding group. I also expect my seat will recline. I have back problems & it is very painful for me of the seat doesn’t recline. In addition, when I choose a fare that allows me a carry-on bag, I expect to be able to carry it on. Not be forced to check it. Thos happened on my flight to MCO & back to Boston. Not sure I will ever fly JetBlue again. Further I bought the ticket through hat deal. I will NEVER do that again. They were incapable of providing an accurate record locator # for either leg of the trip. I had to call them before each flight with me VERY stressed about whether I would actually be able to get on my flight. Who does that? Who books flight & then FAILS to give an accurate record locator? Twice!

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

Poor... food was horrible, boarding very slow, service on board mediocre

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.
