Great overall experience and use of the Delta One lounge was amazing!

Great overall experience and use of the Delta One lounge was amazing!

The gate attendant was not clear w message on flight delays.

Amazing, delta One is extraordinary. Worth the money. They took our bags at the door when our driver dropped Us off at Heathrow.. the Virgin CLUBHOUSE lounge was wonderful and the flight was great. Service food our little pod all near perfect.

Great flight. Thank you for the upgrade to first class.

I liked one of the movies ( which I'm not a movie person" but this was so funny. I had to keep my laughter out loud to a muffle.! I felt too squished in my window seat and the man next to me was not big and bulky or heavy. I like the option of only two seats together. It made it much better for bathroom breaks.

Flight was delayed and not a lot of communication on why until we got on the plane.

Horrible experience. Delta delayed the flight to 11pm which happens. Apparently the pilots were there but we were waiting for flight attendants to arrive from Detroit and they were delayed. They could have made arrangements but that’s fine. What was truly horrible was that at 10:50pm the pilot comes out and says the flight will be cancelled but hasn’t been cancelled yet in the system. It’s being cancelled because the pilots have timed out. As soon as that plane got delayed past 10:50pm delta knew it couldn’t fly. Yet they made us wait around for hours. When the flight finally got cancelled all the area hotels were booked and flights for the next day were unavailable until midday. All I wanted was to spend one day with my family before needing to fly abroad on another delta flight. That will be my last flight with them. I’ll take my 800k miles flown and annual spend to an airline that isn’t so thoughtless.

got ahead of the schedule, nothing else to like. crew management of boarding when overhead bag space was virtually gone in the midst of their priority zone 3 should have been better. but they absolutely did not care. ryanair crew is better than this!

The crew were very respectful. And also they were welcoming.they did help us locate our seats.i enjoyed.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Easy process you definitely need 3 hours to get on board from Fuminchino airport

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

Didn’t have requested food and seats could be more comfortable.

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

Entertainment, clean plane and funny pilot over the intercom was excellent… however, gate agent was rude and was probably a Spirit employee before they went bankrupt… there were 3 flight attendants - 2 of them didn’t want to be there the other one was kind and nice… I want you to recognize how you have to compete with Delta or South West airlines or even American Airlines which would choose over you at any given day from here on out. Please treat people respectfully. If you hate working in this industry - go and work somewhere else. The flight was very empty and it shouldn’t be hard to crack a smile once in a while. Very disappointing… I remember flying Jet Blue back in the day from Dulles IAD to LAX and you guys were super cool and fancy and made flying fun again - truly elevated the experience. Don’t become the next most hated airline… you can do better . I want you to succeed…

Free wifi was almost impossible to get, kept dropping the connection

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

The whole experience at the airport in Istanbul should be made known beforehand. Four passport checks and a huge check-in line as I could not check in online made it a very lengthy and frustrating experience. The flights on Turkish Airlines however were just fine.

Late boarding, had to check the bag even though there was space on the flight and I was I row 7

Unacceptable pre-boarding ticket issues. Paid for and reserved Mint seat approximately a month in advance. Checked in to flight in Mint seat 24 hours before flight. Shortly before flight, was bumped out of Mint entirely, even though other Mint seats were still available and for sale. Was told it was "operational", however seats were still available/being sold. Got to gate and they could not explain it, but the gate agent was able to put me back into Mint (however to a different seat). Nothing proactive done by Jetblue, I would have been bumped had I not arrived at gate early enough to have a helpful gate agent rectify. No explanations from Jetblue.

Diana at the gate was unhelpful which was fine, but she was also rude which I did not appreciate at all.

Forced to check bag, even though plenty of space in overhead bins. Did not appreciate having to wait at baggage claim to retrieve suitcase.

They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.
