Pros: "I always have a consistently good experience on Delta. Everything was great."
Pros: "Everything ok. I was hoping to buy food but glad to see almonds as one of the free snacks. Delta seems to be upping its game a bit lately."
Cons: "No US carrier seems able to master smooth boarding without standing waits."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Cons: "1.5 hour delay...no reason given!"
Cons: "Flight was delayed and completely packed so our family could not get seats together"
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
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: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
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."
Cons: "Very little leg room."
Pros: "JFK to Denver the flight Attendants were once again great. Lots of entertainment choices again. The usual rough air coming into DIA."
Cons: "From JFK to Denver the seats were to close for leg room by an inch or two. The temperature was hot most of the flight."
Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."
Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."
Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."
Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"

Pros: "In a pinch they were able t"
Pros: "Great in every way"
Pros: "Excellent piloting and cabin crew."
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: "Check in lines were crazy long"
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: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."
Pros: "really helpful and friendly service and nice seats."
Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Cons: "Excellent service excellent pilot"
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."
Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"

Cons: "Everything. Had to sleep overnight in airport and was late coming home."
Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."
Pros: "Wonderful, again. Will fly American any chance I get!"

Cons: "Watched a very weird interaction between Muslim (with a hajib) women with a kiddo and desk crew. She wanted to sit next to her child on the flight and needed to switch seats to be able to. Woman was very gracious and understanding that she was asking for an accommodation. Ends up her flight to Philly had been moved to a different gate after they had found a volunteer to switch seats. Volunteer was totally unfazed but Desk crew made it seem as tho the Muslim mom was at fault for the time and trouble they had had to go through to accommodate her. She apologized profusely and was very appreciative for the trouble evernote had gone to for her. . As she walked away the crew looked at each other and shook their heads. Pretty crummy way to treat customers!"
Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."
Cons: "Uncomfortable seats Crying child"
