Great people making you feel great and pointing you in the right direction always

Delta was great because the flight was almost 5 hours so I had access to tons of movies news, etc. so it helped past the time by no other plane WestJet did not have movies so Delta was the best

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

Very bad multiple confusion and miscommunication which i ended up missing my flight.

There was no food, so :( to that one. The flight was delayed by 3 hours. Not Delta's fault. Not the crew's fault. Considering how tired all us passengers were, everything went surprisingly well. The flight crew were very helpful, friendly, and professional. I always fly Delta.

Delta is a perfect partner, offering the gold standard across the board.

Our flight from Detroit to LaGuardia on Thursday 8/20 was delayed from 555 to 910 due to storms and a ground stop at LGA. It’s never fun to be stuck at the airport but I thought the desk crew and captain handled it well and kept us informed. I especially liked how they referred to us as their “LaGuardia family.” I am a loyal delta customer and this is one of the reasons why.

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

The flights were on time; all went as expected which is a big positive! No delays! There was no food or drink service in any legs, which I understand due to the short flight time.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

DCA-LAX No screen on a 5 hour flight (almost) no food for sale on a 5 hour flight (practically) no wifi coverage or speed on a 5 hour flight I should have gotten my money back, shame on American

Delayed flight led to missed connection which led to new flight with 3 hours of delay so our family of 5 went from a 7pm arrival time to 1am Absolutely terrible yet again.

Flight was good, little delayed because of busy plane traffic

I had ridiculously long body search because I have knee and hip replacements

My luggage is missing. I haven’t received it. No one seems to know how I can find it

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

Old plane. Nowhere as compared to non US airlines like JAL.

Flight was on time. Boarding was smooth and orderly. Flight attendants were friendly and professional. Bags came out soon after arrival.

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

The series of delays were very unfortunately - first the captain timed out, then the new captain didn't show up when we were told he would, then the first officer timed out. Those delays were compounded by after boarding, weather came in - obviously that's out of JB's control but it was frustrating after all of the other delays that seemed avoidable.

3 hours late JetBlue flight made me miss my connecting flight to Nairobi Kenya, they did not even offer me hotel accommodation, I paid out of my pocket, they did not know where my luggage was, let say my experience with JetBlue was nightmare.

JFK is the worst airport and JetBlue is the worst airline

Crew at first tried to SELL snack boxes (for an hour-long flight?!?), and it was the only leg of four on which I was charged for a hard seltzer. 😕 Spent extra to select seats in Row 8 for quicker disembarking only to be seated in Row 25. Someone owes me $38 for that!

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!

My screen didn’t work, my seat didn’t recline, the flight attendant was rude and completely dismissive, the airplane was freezing, the seats are way old, slanted and uncomfortable. I payed for a full ticket and got a horrific experience, with a flight attendant who dismissed me even though I was calm respectful and polite.

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

Very poor help no one answering a question regarding seating. Very rude staff. They don’t care, as if it’s not part of their job. Flight was delayed for no good reason and no apologies given.

It was my worse flying experience. It was my first time and last time flying with Jet Blue.

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