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

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.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Terrible. Waited on runway for 1+ hour after landing and then was brought to wrong terminal

My experience with Delta started with my luggage being found ripped open with items missing. The baggage office told me to bring the bag, and I wanted them to see how I found it. The agent refused, so I carried my bag into the office myself. The agent was nice enough to fix the zipper and gave me a red card with a number to call. I followed the steps; first one department, then the baggage department took over. This took more than two hours on the phone. The return flight was okay. The flight lead was checking her meals and then asked if we wanted anything before departure. However, throughout the flight, I had to ask for things because she was reading her book;which I have no issue with if she had been more attentive. At the end of the flight, the pilot appeared annoyed with the flight lead for not following his instructions regarding a meal he had requested; a chicken sandwichand said, "I asked for that for the flight." On the positive side, my work event in Vegas went well, and now I'm home relaxing.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

Flight was delayed multiple time and for more than 1 hr. My onward flight from BOS to MCI was also delayed. These delays have caused me so much inconvenience and Delta does nothing to ensure flights take off on time. No one knew why the inbound flight was delayed and what was the issue.

This flight was originally delayed by ~45 minutes; which is fine. However, there were additional delays due to late offboarding of the prior flight, unclear issues with the boarding process, delays on the tarmac, and exceptionally long taxiing. None of these issues were communicated proactively. Additionally, the flight had exceptionally rough turbulence, which led to a very uncomfortable flight and no traditional beverage service. Again, this is understandable, but it was not communicated up-front by the flight team.

My flight was delayed by 4 hours in 30 minute increments. The gate agents were amazing but the communication was not. We were told that there was a maintenance issue but they didn't know what it was. That didn't inspire confidence. Then they said they found it and it was fixed and the pilot just needed to sign off. Then the pilot needed to talk to the other pilot from the arriving flight and we'd be fine. Then we were waiting for the pilot to call back. Then the maintenance issue wasn't fixed. Then they decided we were getting a new plane (why didn't they decide this earlier??). Fine. But then they announced we were changing gates AND terminals. And we were boarding in 20 minutes. So we all had to run to the new terminal gate. We could have taken off at that time, but we then had to wait for all the people who rebooked on a different flight to book this flight again. That took 30+ minutes because there was only one gate agent. When everyone ditched this flight, I saw it as an opportunity to upgrade to comfort. Delta, the greedy jerks they are, charged me $121. After their delay, their fault, their issues, couldn't even discount an upgrade. They only handed out $12 meal vouchers for the delay. I can't even get a snack from starbucks for that.

If you cant travel Delta One, Comfort Class is the next best thing!

Arrived early, comfortable seats (Comfort+). Mediocre food, poor wifi (intermittent).

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.

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.

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.

Better food than other airlines and the flight staff was very attentive and nice.

It was fine. Not worth the premium price. Overhead bins were so high I could barely reach and no crew offered to help me. Average food. Lounge in Dublin - 51st and green- absolutely appalling. Plagued with hordes of flies, dirty, meager food and beverages. Shameful.

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Very good flight that left on time and arrived earlier than anticipated, which was a plus! The crew members were very welcoming and helpful. However, the temperature on the flight was very cold - almost to the point of extreme discomfort. Additionally, requiring passengers to pay $8 for headphones to access the JetBlue entertainment was disappointing. Those earbud jacks are not used with most technology and would not be able to be used. There was no option to use Bluetooth for my own earbuds. Beyond those inconveniences, the flight was good.

From Edinburgh to Boston was pretty good, actually! From Boston to DCA? Not so much. More food offerings for those w/gluten issues please! I don’t do well w/wheat OR legumes so neither the pasta nor the lentils would have been good for me (or pleasant for those around me on a 6+ hour flight!). Staff on the Boston to DCA leg were brusque compared to those on the other 3 legs of my trip. Also, I paid $19/seat to select 2 seats on the Boston to DC leg and we didn’t get those Row 8 seats but were sat in ROW TWENTY-FIVE😕 Someone owes me $38!

Check in and passport control were seamless and efficient. Plenty of room in overhead bins. Our original seats were separate but crew at the gate put us together in finer seats. I also had left my phone on board and the Jet Blue staff were so helpful in retrieving it after I had left the baggage area

Flight was delayed. But my finances flight with JetBlue a week before same route was extra delayed and then cancelled at 2am when his flight was suppose to take off at 7pm was never provided a hotel or anything. Came back to airport and his rescheduled flight was cancelled again for 2 days later. Was told since it was a weather issue they don’t do refunds. But that’s a lie because I booked him on another airline at the same time and they were able to take off perfectly fine

Separated a pair of family members(father and teenage daughter) on all legs of the flight that were booked together, just to create an upsell. Food was horrible and only catered to vegetarians and gluten free crowd. I’d rather give more of my money to another straight shooting airline.

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

For whatever reason, I could not check in online. Kept getting the "It's not you it's us" message. Even when we tried the kiosk at the airport - same results. The check-in person had a very difficult time getting our boarding passes together despite the fact that we could show confirmation on the jetblue website. After a very long time we finally got boarding passes. The only other issue is, my vegetarian meal featured chicken.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.
