Delta is one of the best airlines I have flown

10.0 ExcellentKellie, Apr 2024ANC - SEA

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

Flew business class. Everything was excellent. No issues at all. Not very many “good” movies to choose from. But lots of mediocre ones

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

The best experience that I have had traveling with JetBlue!

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Crew was just ok. Flight was packed. On a 3/4 hour flight I would hope they would come around more than once to see if you needed anything further. Not very attentive.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

Nothing. Jet Blue is a great choice for me And I’m going to miss flying with them Since I travel to Lima Peru very often 😞😞😞

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

The flight was delayed due to weather issue…WiFi did not work and even though I wanted to pay for WiFi I couldn’t buy it. Overall very disappointing even though I paid and reserved Business class

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

Everything was really good but the seats are not very comfortable.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.

The boarding attendant was slightly rude when I asked about checking our stroller. Made me feel like I was bothering her.

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

Not much seat room, but that was unexpected. But the seat headrest was very uncomfortable.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.
