Airline reviews

Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."

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 !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Pros: "Christina brown was amazing at gate"

Cons: "The main economy seats were far too narrow."

Cons: "It was a Great flight. I always enjoy flying Delta"

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: "Flight was delayed and completely packed so our family could not get seats together"

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

Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

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

Pros: "Flight crew was ok"
Cons: "Missing my connecting flight due to Delta incompetence and spending Christmas travel in ATL again."

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."

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: "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: "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: "In a pinch they were able t"

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: "Check in lines were crazy long"

Pros: "Love the inflight entertainment and the usb plug for phones. Flight left on time and go in a little early"
Cons: "Did not love getting charged $2 for headphones and the girl sitting next to me getting them for free. Super annoying"

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: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

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: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

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"

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: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."

Pros: "Very professional and caring."

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

Pros: "Crew was great."
Cons: "turbulence"

Pros: "1st class flight attendant sat through the entire flight (except for offering drinks and food early in flight). There were passengers NOT wearing masks through the flight but she wouldn't know that since she never left her seat"
Cons: "just about everyting"

Cons: "IFE was not streaming movies, WiFi on but not loading"

Cons: "Spacing people out until this covid is over"

Cons: "I can’t believe with all that’s going on American doesn’t care. The terminal was packed with people. Terminal B Charlotte airport. Packed!!!. I had no choice. In the future Jet Blue. I know it’s all about making money the flight was packed. Logan airport Delta every other set has a sticker don’t sit here"

Pros: "The crew was great. I showed up to early and they were able to adjust my flight so I wasn’t sitting at the airport all day. Best service."

Pros: "Everything was great"
Cons: "Nothing"

Pros: "Appreciated the pilot keeping us informed re: turbulence and avoiding it"

Pros: "I loved everything! Best flight experience in a long time. Really easy, on time, great window seat, thank you"
Cons: "Me probably. You guys were excellent!"

Pros: "The gate crew handled the delay as best they could."
Cons: "Seems that a crew timing out could be better anticipated."

Pros: "Nothing"
Cons: "Not allowed unleashed dogs to take my seat or be in my flight"

Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."

Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Pros: "Overhead bins were newly done with plenty of space since carryon can be placed vertical on side. Decide holder built into the seat was very nice."

Pros: "Nice staff"

Pros: "Pleasent"

Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."

Pros: "The plane looks like new. Great seats, phone and tablet holders at the seat back, USB outlet and a smooth flight."
Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."

Cons: "3+ hour flight with no TV/ entertainment"

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Pros: "They got us there quickly."

Pros: "Ahead of schedule"

Pros: "Seats were too tight and too close together."

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."
Cons: "Airline misplaced my boyfriend's checked back with our duty free Portuguese wine in it. It still hasn't been delivered to him the next day. They had three hours to get the bag on the flight."

Pros: "Nothing in particular"
Cons: "Outlet did not work"

Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."

Pros: "Same"
Cons: "Same"

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Wonderful, again. Will fly American any chance I get!"

Cons: "No tvs!!"

Cons: "the new seats are awful"

Pros: "Tv and power outlets"
Cons: "This one attendant didn't get her name but was very cold to me"

Cons: "Long delay"

Pros: "Crew"
Cons: "Small plane"

Pros: "Good serice,"
Cons: "Good service to switch flight pattern from greenville to new bern but still a delay that cause a 2 flight connection. Lots of on-line issues with check-in, overall a stressful day, hopefully it will all work out!"

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "Everything"

Cons: "The flight was 3 hrs late, of which 1.5 before boarding, and almost 1.5 stuck in the plane."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "It was quick"
Cons: "No drinks handed out."

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 cabins are very cold and the seats stiff. Food was just dry pretzels and soda, coffee etc. Landing was smooth. I just wish more information was given as to why we were delayed etc."

Cons: "Seats too small and the gentleman next to me was a big guy so crowded over into my seat some."

Pros: "Very friendly staff"

Pros: "The plane was new on the interior and comfortable."

Pros: "I liked sitting next to my friends."
