Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

Everything was pretty good. I would like to have more drinks (water) during four hours of the flight.

This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

Connection flights should be spaced out farther because too close I missed my connection.

The flight was way too HOT! And the plane did not have any in-flight TV entertainment.

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The boarding agent and checked bag agent were both rude. It only takes a second to be kind. However, the flight crew was amazing. I got a turkey sandwich and it wasn't bad---not great but not bad. The internet was my biggest problem. This was a work trip and I REALLY needed the internet to meet a deadline but it didn't work for 80% of the trip. Very disappointing.

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Jet Blue sevice was good. Just don't understand why they charge for earphones to listen to flight entertainment. Other than that, everything was excellent.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The crew was not nice this time. I asked for a drink one time and the girl didn’t say anything to me and just got me the hot drink while walking super fast to the back. We were sitting in the back and she wasn’t doing anything except socializing. She was upset I asked for something and she had to do her job. I also didn’t fully have it in my hands when she handed it to me so it was dangerous. She was abrupt and rude. She wouldn’t allow for people to spread out like previous flights we had been on if they were empty, and there were empty rows. It was strange and she enjoyed being angry at us.

They lost my luggage and refuse to help. Terrible airline. I've never experienced worse customer service in my life. Pretty much just told me too bad that I lost all my luggage, not caring that I am stuck in Europe for 2 weeks with absolutely nothing.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

As with all airline's seats, a little more padding would appreciated. Especially on longer flights.

It was a late flight; crew was invisible. Zero air flow - the tiny plane was a sauna; the left the lights on for 1/2 of the flight; there was no water. Never again.

What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.

Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.

Smell of jet fuel was overwhelming from inside the plane while on the ground at take off and landing. Gave me a sore throat and a headache. During boarding, de-planing, taxi-ing, waiting in line for take off, etc. Also, the vents didn't have enough cool air coming out (yes, off course I opened it all the way) so the whole flight was hot and stuffy. But just my vent - all the vents.

The flight had a 6 hours delay. This should not happen to anyone. Airlines should provide an alternative with no additional costs.

Seat comfort was poor (no lumbar or lower back support).

Pilot navigated severe weather/snow storm with skill. Described his intentions clearly

The American flight was a connecting flight to an international flight. The international flight has a 2 check bag rule. Despite being informed of this, American would only check 1 bag and wanted 100 to check the second (basically a 3rd carry-on) to NYC. Subsequently tsa took a sealed container of maple syrup and a few other things that couldn't be in carry-on plus I had to lug around 3 pieces of luggage for the entire trip. The American reservation was made with the international and American actually checked the one piece the entire way to China. This is one of the reasons that I will avoid American airlines if possible in the future.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

It was a good flight. Of course it was full, but it went well.
