I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

They lost my bag and I still haven’t received it yet

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Boarding was a disaster being moved by Air France by bus to the plane. The plane should have been at the right gate.

Flight was late over a hour just like the first one. WiFi was down.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

They charge me for luggage which is was included on the ticket

Lost luggage, 2 bags were badly damaged and one of the bags came open.

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.

Economy seats a bit small but other than that it was all good.

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.

The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.

Flight was delayed 3 hours. No food on plane besides snacks

Nice plane, with TV, comfortable seats and leg room. Updated regularly on time changes

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

Boarding was easy, the flight left on time and even landed 20 minutes early. The food was plentiful and really good! The crew was kind & helpful. Overall it was an exceptional experience!

The flight was safe, confortable and convenient. Thank you. I hope to come back soon!

temperature was too cold there should be free blankets, seat are very uncomfortable, entertainment is limited.

Even in the premium economy, I found the seats incredibly uncomfortable. I hated that booking through Kayak, it wasn't clear that it was a Level flight, not Iberia. Everything felt cheaply made and not at all worth the airfare we paid.

I wish they could put the pre-tsa check on the tickets or global entry.

We upgraded to Business class paying approx. $1,300. Despite the upgrade, we were still required to pay an additional €70 for a checked bag. Furthermore, we were informed that another €70 would have been charged for our carry-on bag, as it was 3kg over the limit. To avoid this, we had to move clothing from the carry-on into the checked bag, which was both inconvenient and frustrating. Given the significant amount paid for the Business Class upgrade, we found this treatment to be quite appalling and disappointing. We expected a higher level of service and consideration for our luggage, and this experience did not meet those expectations.

The staff on our flight from Charlotte to Boston were very friendly.
