Delta is one of the best airlines I have flown

10.0 ExcellentKellie, Apr 2024ANC - SEA
Read more about Delta reviews

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.

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

The boarding was one of the worst I’ve ever experienced. The fault lays on Ohare Airport and not so much the airline. The waiting area by the gate was the size to accommodate a regional flight for 20-30 people and right next to a busy walkway. When you cramped nearly 300 passengers into that space is was unbearable.

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

Loved the check-in experience. Very friendly staff and not crowded. I did wind up with a middle-middle seat, which was quite uncomfortable. Always appreciate the very professional staff on TAL.

Paying for reserved seats and never received the seats I paid for !! Just fake and a surprise out of their " box "

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

First class payment but wife’s seat broken, would recline but not lay flat. On previous flight, delays and ground crew malfunctions connecting jetway made us miss flight to Houston. I asked twice for a cart to assist us getting across the massive Istanbul Airport, but was denied. We are both over 70.

My flight had two legs. When checking in at the first leg the agent offering for a deal to upgrade the leg to first class for $199. He then claimed I would be able to upgrade the second leg once I got to the next airport. I declined and when I inquired about upgrading at the second airport, the cost was $1,300. I also had an issue at the airport lounge. I am allowed one guest in the lounge. My friend came in the lounge for less than 5 minutes and left when she couldn’t get a sleeping suite. I wanted to bring in another friend. The airport staff first started acting as though they didn’t understand English and then became upset when I asked for their names so I could file a complaint. As an elite member I knew they could do more but were not. One of the agents started over talking me and walked away mid conversation dismissing my request for assistance. A man claiming to be the manager said you were asking for her name. He also never tried to assist me or see what was going on. He claimed the interactions were recorded and management would see everything. I’m not sure how that would assist me days later. I am sure it didn’t help that I was a black American woman.

Better attitude training for staff at airport, better training for flight attendants, better food, don’t put us with all the crying babies that cried nonstop for 12 plus hours.

Crew announced boarding started and they asked passengers to form a queue. Actual boarding didn’t start and queue was not moving for around 40-50 mins. Very poor management.

It was a terrible airline. The air hostess and the people in the flight, just very rude.

Crew on this flight was terrible. Especially one practicular female , she was harassing us and other families with children. Flight was good overall, if not her being rude and aggressive

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
