Airline reviews

Cons: "Not delayed"

Pros: "this is the airline"

Pros: "You know what you are getting with Delta"
Cons: "The economy seats were really tiny, this made the flight fairly uncomfortable"

Pros: "The crew was very friendly. The plane was very quiet (except for noisy crying babies)."
Cons: "Unless you can afford the higher priced "comfort class" or first class seats, the seating is very, very cramped on Delta's 757s. It's a good thing the flight was only 5+ hours (but that's not long enough to get any decent amount of sleep on this flight scheduled as a redeye)."

Cons: "Better allergy aware food."

Pros: "Friendly crew"
Cons: "We reserved exit row seats and when they changed the plane they gave our exit row seats to others."

Pros: "N/a"
Cons: "The crew members were very rude and they called me an IDIOT!! Yes they did because the forced me to check my carry on bag and i didnt want they are racists"

Pros: "I was in Comfort+ so there was a bit more leg room than standard economy"
Cons: "Even with Comfort+ things are tight."

Pros: "room and services"
Cons: "can't think of anything"

Pros: "We left early"

Cons: "they let someone get off the plane and it delayed the flight an hour and a half which caused me to miss my connecting flight. I now have to sit for a 5 hour layover"

Pros: "wonderfu crew... very helpul`"
Cons: ".."

Pros: "The selection of movies was great."
Cons: "The food. No herbal or decaf tea. No decaf coffee. The regular coffee and regular tea was awful; I like strong coffee and tea but on the plane it was terrible. The was not a vegan option for dinner. I thought the pilot announced complimentary beverages; soft drinks, coffee, tea & alcohol. Perhaps I was mistaken or maybe he was. I like the seats (reclining back with the seat bottom moving forward) except the seat bottom is entirely too hard and was bad for my back. The hot towels are a welcome touch. The ride was smooth, the pilots did a very good job."

Pros: "Everything went great. Flight left a little late but was fine and only arrived a little late. I like the side wings on head rests really help."
Cons: "Seats are always hard on long flights."

Cons: "After we boarded and were already sitting in our sits the stewardess came and removed our bags from the overhead compartment for another person with a larger bag! We ended up storing our bags under the sits in-front. The way it was done it was rude and with no consideration for our comfort."

Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."

Pros: "Easy and quick"
Cons: "No complaints"

Pros: "on time, good food, good films enough space to sleep in economy."
Cons: "the stewardess only went up one side of the plane offering eye shades and when i asked for one she seemed really miffed."

Pros: "Great service throughout. Friendly attendants and easy boarding/deboarding processes. Would fly international with them again in a heart beat."

Pros: "The flight was ontime, boarding was okay. Disembarking seemed a little slow."
Cons: "Seats have gotten narrower and closer together and it was a new plane which seemed to have more slope to the wall which meant even less room in the window seat. Too warm in the plane"

Pros: "We didn’t order food and there was no online entertainment"

Pros: "Delta flights run one time and their fleet seems newer than most with comfortable seating. Having free movies in the seat back ahead of you is a big plus with a good selection of movies. Snacks are good and crew is always friendly and accommodating. We fly almost exclusively with Delta for the aforementioned reasons."
Cons: "Boarding is a hassle no matter the airline with few exceptions. You would think someone could figure and efficient method to get people on the planes. I suppose it could be the public that is the problem. Not a problem with Delta they run a good airline."

Pros: "Nice people. Very helpful."
Cons: "LOST MY BAG IN BOSTON BEFORE EVEN TAKING OFF!!!! Did not make it, and then won't deliver it when it makes it to Kathmandu! This is most distressing."

Pros: "The overall flight was good."

Cons: "Jet airways sucks"

Pros: "The only positive of this leg is that it was less infuriating than the flight from RDU to Boston"
Cons: "Delta's partnership with Go Jet seriously compromises the legacy carrier's reputation. I am a Delta fan - although flexible enough to use other choices when necessary. I will no longer fly a Go Jet operated leg when other choices are available. For my trips to Boston, that means Jet Blue. Sorry Delta. I'll see you back on a true Delta route."

Pros: "Great crew and passengers"

Pros: "Entertainment offered, USB charging options."
Cons: "Too much food offered."

Pros: "Within Europe KLM short flights are very good. They give you a snack and something to drink without charge."
Cons: "Seats,are a little tight but like most other airlines."

Pros: "Nothing."
Cons: "Reservation. Checkin. Seating. Flight."

Pros: "It was a really good flight minor turbulence towards the end. Flight was on time, smooth flight. NO tvs on this one."
Cons: "I wish they had more snacks like JetBlue but all was fine. TVs on every plane would be nice."

Cons: "The process of checking was very poor. One line was serving all of the Delta flights. Agents were very slow. Even when they started to serve my flight with priority still no impruvment. The agent who served me was so lost that he could not find the page with my picture and name in my passport!!!"

Pros: "It doesn't matter how good all of the above were when one of our bags did not make the connection in Atlanta and when it was delivered late at night to my home and it has been torn beyond repair"
Cons: "Bag did not make the connection and it was damaged beyond repair"

Pros: "On time, leg room, entertainment, service."
Cons: "N/A"

Pros: "The speediness if the crew to get the flight boarded and in the air, entire process form boarding to unboarding was about an hour."
Cons: "Plane was loud and very stuffy, but the flight being so shore made it managable, overall good flight."

Pros: "Overall flight was nice, but almost miss my flight!"
Cons: "Almost miss my flight due to Delta being short staffed at the ticket counter in the early am. Had a small issue to validate my passport in the automated cheek-in botths and waited over an hour to get them to personally validate. terrible experience. There were several of us with the same problem. I chose Delta given their prestige for great customer service, but they definitely need to do something about some of the folks at Logan's terminal."

Cons: "Old plane Zero entertainment First class seats worn thin and uncomfortable. I've been flying AA quite a bit lately and thought I'd give Delta another try. Too bad, it's clearly not up to today's standards"

Cons: "Seats don't have wings to rest your head on. The distance to the seat in front of me was of course way too small making it nearly impossible to use my computer."

Pros: "Smooth flying"
Cons: "The entertainment units were terrible. Touch screens effectively impossible to operate in this 737-800."

Cons: "I left my wallet on this flight. It was extremely frustrating that I was unable to speak to a live person to find out if the wallet had been recovered. I filled out the form online and now have to wait 2 to 3 weeks!"

Pros: "Boarding was efficient and easy. For the first time on any airline, the crew was over-the-top friendly and my special meal request was excellent."

Pros: "It's what I didn't like....as a Sky Miles member I should get a free bag. Small aircraft for a FL trip."

Pros: "I liked nothing, because the flight was 4hrs late and had 20 on standby."
Cons: "4hrs late, 20 on standby, missed connection, had to travel a day later and spent 14hrs in the airport."

Cons: "I'm just glad that we got to the airport 2 1/2 hours early because we needed it. We had to check a dog so we had to go through the special needs line, they had 2 out of 20 of ticket lines open. My wife also needs a wheelchair and after 45 minutes of standing in line, I spoke to one of the idiots that are supposed to be there to help and he went and got a wheelchair which I had to push my wife in the wheelchair through the zig zag line with 2 large suit cases and a dog. It took us an hour and a half to get tickets and then they called for someone to push the wheelchair and we where told to wait for them there. We waited for 10 minutes for someone to come but no one came so I started pushing her towards the Sercurity check line and finally someone came to push her and he stayed on his phone the entire time. When my wife got to the point where she needed to walk through the metal detector she was having a little trouble getting out of the chair so they told her to just stay in the chair and they would push her through in the wheelchair. When she got through, they almost strip searched her and patted her down like she was a criminal. That took another 25 minutes!!! They the guy pushed her to our gate and insisted on taking the chair back with him, so 5 minutes later they asked if it was anyone who needed assistance getting on the plane. I went up and told them that my wife needed a chair to get on the plane so they had to call and get another chair which took another 10 minutes and finally we got on the plane. It took us 2 hours and 15 minutes to get a ticket and go through Sercurity!!!! Very very very unprofessional!!!"

Cons: "Free streaming movies on WiFi did not work (the system was broken on this aircraft according to the customer support). We had 3 people flying together but did not get the seats assigned in one place. Yes, we did not pay extra for confirmed seats but since we were buying 3 tickets I think 3 seats close to each other (if not in one row) should be expected."

Cons: "make me sleep in the airport unexceptedly"

Cons: "They lost my duffle bag, and when they found it, my bag was in a whole different state, and once I finally received my duffle bag my items were wet and damaged."

Pros: "Why did my seat assignment have to be done at gate. I booked early and had picked a seat on eac flight."

Pros: "The staff was pleasant and very caring. I traveled with my sister who was in a wheel chair due to he ability to walk long distance and they were just outstanding. And I want to Praise Delta for their understanding and most caring and assistance in assisting me on changing of my return flight due to my husband had a stroke on Thanksgiving Day. I was able to leave out on Friday (11-27-2014) with no problem."
