Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Pros: "Great crew."
Cons: "As always, the seats in basic economy are as small as possible without actually being standing room only. I'm 5'7" and my knees are only about an inch from the seat back in front of me."

Pros: "Christina brown was amazing at gate"

Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Cons: "Great flight"

Cons: "crj900 from BUF-MSP is a wreck. worn out, uncomfortable seats, cold air coming from floor toes were numb for about 20m after flight. Flight delayed, missed connecting flight, lost comfort+ upgrade I paid for. No excuse for pitch in main cabin on 737-900 ER."

Pros: "Nothing remarkable"
Cons: "Delta was ordinary"

Pros: "Yes"

Pros: "The crew and entertainment options are great. Relatively comfortable seats by today's standards."
Cons: "Literally any of our flights could have been on time. None were."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Pros: "Love the fact that the head rests move to support your head better."

Pros: "The seat was great, I wish all seats on the plane were that comfortable"
Cons: "Nothing, everyone was great"

Cons: "No meal option and my video screen volume did not work"

Pros: "Boarding was easy."
Cons: "I am 6' 1" tall and weigh 220, so not out of the ordinary and I felt like I was stuffed into a sardine can."

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"

Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"

Pros: "Delta cramps people into these planes and forces you to put your bags under a seat because they stuff at the overhead spaces. They nickel and dime you for every single thing. There was even one person I saw who had to pay for his headphones to listen to the onboard entertainment. I think Delta should quit being so cheap with the profits they make and give it back to your flying customers. It borders on gouging."
Cons: "Delta cramps people into these planes and forces you to put your bags under a seat because they stuff at the overhead spaces. They nickel and dime you for every single thing. There was even one person I saw who had to pay for his headphones to listen to the onboard entertainment. I think Delta should quit being so cheap with the profits they make and give it back to your flying customers. It borders on gouging."

Pros: "Entertainment choices were excellent, many new movies available, so I was able to see movies is been meaning to watch. There were drinks available."
Cons: "The air vents barely trickle out any air anymore. No relief to be had. Airline crews say hi and goodbye but that doesn't make them friendly."

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Pros: "The Delta service desk was great! We wanted to get an earlier flight home and the Delta Rep got us on standby quickly and with a smile."
Cons: "Some chaos getting on the flight. The area they have set up for the different sections to wait before getting called weren't marked very well so everyone was bunched up and confused. Once they started calling the sections it was fine. Not sure why they even had the marked areas."

Pros: "My upgrade and breakfast were fabulous!"

Pros: "Staff very courteous and professional"
Cons: "None"

Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."

Pros: "Everything was perfect !! Staff friendly"

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "just about everyting"

Pros: "Entertainment on seats"
Cons: "I sat in seat 12A- the window was so hot it was burning my arm and I was extremely hot. Not sure if it’s from the engine heat or sun but it’s probably a mechanical issue that the 737 should address. Horribly uncomfortable trip."

Pros: "Same"
Cons: "Same"

Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."

Pros: "Nothing"
Cons: "The flight was cancelled. this is the third flight that has been cancelled to this destination. I waited for 7 hours in the airport and caught a flight on stand by. Because this has happended to me before I knew how to get a stand by ticket right away even though I was scheduled on a flight for later that day. Much later."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Pros: "The food"
Cons: "Crew and the fact that they lost my bag"

Pros: "Very friendly staff"

Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"

Pros: "Nothing"
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag.
