Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Cons: "The main economy seats were far too narrow."
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"
Pros: "Love the fact that the head rests move to support your head better."
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."
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: "Boarding was quick"
Cons: "No entertainment, plane was small"
Pros: "Good entertainment selection and great crew"
Cons: "Seats are more uncomfortable relative to other airlines"
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Pros: "Flight crew was ok"
Cons: "Missing my connecting flight due to Delta incompetence and spending Christmas travel in ATL again."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
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: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
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: "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: "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: "In a pinch they were able t"
Pros: "Everything was perfect !! Staff friendly"
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: "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."
Pros: "free texting and entertainment!"
Cons: "our flight was delayed half an hour."
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 boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."
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"
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"
Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."
Pros: "The staff of the flight were very friendly and attentive. They were great!"
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: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "Attendants and entertainment"
Cons: "Delays for no explained reason"
Pros: "plane had individual movies for free with each seat!"
Cons: "There are too many announcements on the screen before you can start watching entertainment. It takes about 15 minutes."
Cons: "Short flight, would have appreciated if when asking for pretzels the flaggt attendant didn't hand me the spare bag of his pockets."
Pros: "Really enjoy flying first class."
Cons: "Excellent"
Pros: "Good entertainment choices."
Cons: "Uncomfortable seat with insufficient legroom wouldn't recline. Inadequate overhead storage (full flight)"
Cons: "The seat went back three inches. I was about to spasm after 4 hours. No movement whatsoever. The flight crew could have moved me but I suppose they were told not to as I had a cheap ticket."
Pros: "It was standard AA service"
Cons: "After flying in Delta Comfort+, American’s forward economy section is just nothing."
Pros: "Crew was tight, friendly, flight comfortable & painless."
Cons: "Sat waiting for gate for 30 min"
Cons: "There was literally no entertainment for over three hour flight and our flight was delayed an hour while we were on the plane."
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: "The crew was polite and professional"
Cons: "At Miami check in, American had 40-60 automated terminals available for self check, but only had EIGHT open for use. Caused a needless bottleneck and the transition from there to the bag drop was also poorly laid out and did not provide a logical nor efficient route from one to the other. fix it!"
Pros: "On time flight. We were even a little early."
Cons: "Those seats are just crammed in there aren’t they?"
Pros: "The notifications regarding my connection and baggage claim."
Cons: "Nothing."
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."
Cons: "American Airlies no longer partners with T-Mobile for free WiFi. :-("
Pros: "Crew was good, flight was on time"
Cons: "Old plane, no TVs"
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."
Cons: "Flight was delayed so had to drive to connecting city just to make it home."
Cons: "My bags were not checked all the way to my destination, I had to get them re-tagged and checked for this part of the trip and the American Agent was EXTREMELY rude and made us pay oversized bagge fees even though our baggage was within the Qantas allowance, the main carrier for our flight."
Pros: "Love FLIGHT WITH AMERICAN AIRLINES."
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: "The sound on the entertainment system in my seat didn't work well. Also, the flight was really late getting in to Denver."
Pros: "Friendly crew"
Cons: "Tight seating leg room non existent."
Pros: "Fine for a domestic flight. Normally, American Airlines offer a small snack to go with the drinks. But on this particular flight, they went the United way and offered nothing but drinks. Crew was pleasant enough during the flight, although they didn't greet half of the passengers entering or exiting the plane."
Cons: "Flight was a little late taking off and therefore getting to Denver. But there was no announcement about it. There was one announcement from the captain, but it was so soft that I couldn't hear anything. Upon landing and arriving at the gate, we stood there for a while with no lights on and seatbelt sign on, but no explanation of what was going on. There was no welcome to Denver message either. Maybe their announcement system was down."
Pros: "Landing and deplaning"
Cons: "Literally everything else"
Pros: "Our plane was given to another group going to Orlando so we were delayed almost 4 hours. This after a 5 hour layover."
Cons: "Gate lady was funny about being pissed about the delay."
Pros: "Great service in first class"
Cons: "N/A"
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."
Cons: "Flight was delayed by 90 minutes because the incflight mint flight was late"
Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."
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."
Cons: "Food"
Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."
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: "The onboard entertainment selection was excellent; great movie selection, wifi connection, and flight details. A winner! So much so that I chose to binge watch movies and not sleep!!"
Cons: "Long delay"
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!"
Cons: "I can't rate it because they canceled my entire itinerary without so much as an email. I did not take my flight to Wilmington via my original flight. I had to book another flight because the change fees were too expensive. I did not know that my return flight to Denver had been canceled until I was checking in a few hours before my flight. I was told my ticket had no value. Awesome! It really stings that I then had to book a new return flight, and because I am a teacher who makes about $23,000 a year, I had to book the cheapest flight, which was with American. I do not plan on giving them any of my hard-earned money in the future if I can help it."
Pros: "No excuse on a night flight does the temperature to be 80 plus degrees on the plane."
Cons: "The plastic seats and extreme temperature was brutal. They shut the AC off of down somehow."
Pros: "Entertainment."
Cons: "We sat on the runway for 3.5 hours while the crew cleaned up a fuel spill and we waited for a different co-pilot."
Pros: "I fly this route with American pretty often. The cabin crew was good. Everything else seemed sub par."
Cons: "Our take off was delayed, officially due to fueling the plane, but if the plane wasn't fueled ahead of time, someone failed to do their job properly. Also, while I'm starting to think that A320s just suck mechanically for landing (they always seem to land harder than a 737), this one seemed a little extra rough."
Cons: "Unexplained delay in leaving but only arrived about 10 min later than scheduled. Took an hour from pulling into the gate for bags to arrive though which caused me to miss my shuttle. Never had to wait more than 15 min for any other airline at DIA."
Cons: "They did not check the toilets before we left so we were diverted to St. Louis and I arrived in charlotte 3 hours late"
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: "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."
Cons: "When your on your honeymoon it sure would be nice to have a seat next to my husband like we requested."
