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.

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.

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.

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.

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.

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.

Had to wait over an hour in line for a Jet Blue agent to appear at the the counter. Ended up a customer service agent from another airline lines helped to check us in, and boarding pass,

I propose enhancing the legroom across the entire cabin seating area and expanding the snack selection. The airline companies should prioritize customer needs over the extravagant and unjustified salaries of upper management.

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Staff was very responsive and nice. Long delay because of mechanical issues was a problem.

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!
