Flew in first class. It received service and attention that would be considered poor even by economy standards.

Flew in first class. It received service and attention that would be considered poor even by economy standards.

Great quik boarding, friendly gate agent and crew. Let early

Breakfast before landing was a reheated breakfast “calzone” which was not good, at all. Otherwise, food was good. Crew not very attentive for taking trash from passengers being a little slow in eating.

Surprisingly the coffee was pretty good and they had a gluten free bar handy!

Gate agents call groups one and two and give about 3-5 minutes for each group to board, then the call groups three and four together and it causes a bottleneck in the line. Give each group 3-5 minutes to board before calling the next group.

The captain was running late from landing from a prior flight. We all boarded then had to sit and wait for like an hour for him to arrive. I don't understand why you would have us board knowing that we would have to all sit and wait on the captain for an extended period of time.

We sat at the gate for over 30 minutes, with no indication as to why

I didn't really interact with any of the crew since we had a bumpy ride and no refreshments were distributed.

It was delayed over an hour and a lot of announcements disrupting movie.

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

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,

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

Paid relatively a lot of money for a not comfortable seat. I would not take this service again until seating is improved. Food also not up to standard for price paid.

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.

KUDOS TO ALL THE CREW PROVIDING ASSISTANCE WITH PASSENGERS ON A WHEELCHAIR. ON BOTH FLIGHTS THEY HUSTLED TO TAKE MY RELATIVE TO CONNECTION ON TIME. THEY DESERVE A LOT OF CREDIT!

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.

Good experience. Flight was on time staff was pleasant. One of the airlines I would highly recommend

Boston sucks. Everything after 4p is delayed. AA switched planes on us so we ended up being 1.5 hours late (plus the delay at Logan). Not sure why the airline says it is on time until 1 h before the flight and then it becomes a rolling delay when they knew the incoming flight was arriving after our scheduled departure time. The crew was great as were the gate agent and ground crew. Just operations that sucked.

Food was horrid. In my opinion inedible. They did offer some sorbet and one small dish of fruit. Stewards were super stingy with water, coffee, etc.

Flight was delayed significantly at take off and landing. Confusion of gate assignment with back and forth. Overall, makes for a very unpleasant experience that appears to come down to inept operational management.

My experience was excellent for a business trip. I like the smaller jets because everyone gets either a window or aisle seat and the boarding and de-planing goes much faster. I really like the schedule American Airlines has between Atlanta and NY - lots of options. Crews are great and very accommodating. Sometimes the flights are not full and they let people move around once the boarding doors are shut to spread out.

It was delayed a lot longer than 10 minutes because we arrived 45 minutes beyond our original arrival time. We sat on the tarmac waiting to take off for a very long time. The seats and entertainment options on American were not good and very limited. The ability to text via WiFi for free was nice, but that seems to be standard on mainline flights. Also, gold status really does not do anything for you anymore.

Primary flight attendant in FC wasn't that engaged throughout the flight. All other aspects of flight were good.

We waited over 30 minutes for a gate in Chicago and more than 15 minutes for the doors to open. Cookies were missing from the menu.

On-time, direct flight is great. Having one bathroom out of order was unfortunate.

I sat in seat 22D near the back right of the plane. My phone battery was getting low, so I plugged my charger into the power outlets below the seats in front of me. They did not work. When I asked the flight attendant whether this was the case for the whole plane he said, "No. It's only this one. It hasn't worked for months". This should be noted to whomever services this plane so that maintenance can fix this for future passengers. I was on Flight AA5614 from Grand Rapids to Philadelphia on Wednesday, September 23, 2026.

Check in was easy. Flights were smooth. Flight attendants were courteous and friendly.
