Pros: "Quick and painless, and so appreciate Delta’s respect for social distancing while other flagship carriers have returned to booking full flights"

Pros: "The timeliness of the flight and the service during the flight."
Cons: "The tagging of the bags. The bigger bags should be the only ones tagged. Smaller bags that fit in the bin should be allowed in the cabin."

Pros: "The best"
Cons: "Nothing"

Pros: "Good seats"
Cons: "Flight was delayed and my luggage didn’t make the plane."

Cons: "Worst"

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: "DTW to FLL, plane was delayed coming from BOS to DTW 5 hours for BOS weather. The plane arrived & they announced they would turn it around ASAP. They started the boarding process & then stopped it stating that a crew member had timed out. Delayed hour to FIND one. Shortly after delayed overnight."

Pros: "The flight was on time the crew and captain was very helpful. They got us on and off quickly and safe"
Cons: "Nothing"

Pros: "Crew was good seats were too tight"
Cons: "better seats that come with a basic fare"

Pros: "The only thing I liked about the experience and flight was the Delta Sky Club"
Cons: "Everything"

Cons: "Taxied at ORD for 45 minutes waiting for a gate to vacate."

Pros: "Amount of food!"
Cons: "Quality of food!"

Cons: "First class seats were too close together. It was very difficult to get out of you seat into the aisle. Food was not what it should have been for 1st class There was no wall between 1st class and coach giving little privacy when I worked my laptop. it was in direct view of the middle seat in coach"

Cons: "No wifi"

Pros: "Flight attendants were very friendly."

Pros: "The seat was comfortable"
Cons: "Seats could be a couple of inches wider"

Pros: "We had exit row seat, most uncomfortable ever, video devices both broken. Will never sit in exit row again would have been better off in basic economy"
Cons: "Fix broken seats and tv screens"

Pros: "Chairs was comfortable"
Cons: "I had a kid kicking my chair the whole flight."

Pros: "Comfortable seat for a short trip."

Pros: "With all the competition among airlines and the cutbacks we suffer as customers Delta manages to make you feel like you matter still. Timely boarding, actual help with finding seats making boarding efficient (not just hurrying you along), updates from the cockpit that you could hear and understand, multiple choices in snacks-one even a healthy option, staff that was friendly and interested in making it a good experience not one that seemed bothered they had to work."

Pros: "Enjoyed the ease of check in the spacious gate and the cleanliness of the planes cabin"
Cons: "No complaints"

Pros: "Nothing - missed flight"
Cons: "Need to reschedule flight to tomorrow morning...."

Pros: "Not like"
Cons: "I have Sky Team Elite Plus Platinum but not fare anything!"

Cons: "My flight was delayed, which would have caused me to miss my connecting flight. The customer service person was not at all helpful, and told me there were no other flights available on any airline until the next day. However, I was able to go online and book another flight immediately...which means that she was either being disingenuous or actively undermining efforts to get me home in a timely fashion. Very disappointing and as a SkyMiles member would have thought there would be some level of common courtesy dealing with a non-weather related delay that drastically impacted my travel plans."

Pros: "The crew was very professional, hejpful and had good attitude towards the passengers. This made the flight easy and enjoyable."

Pros: "Our flight attendant was excellent. Service with a smile."
Cons: "We almost missed the flight sitting right in front of the gate. No announcements could be heard in the gate area and when we asked, they said they were already removing our luggage, Very odd. Food was terrible! Choices were pasta and cold chicken salad. I had the pasta, which was bland ravioli in two bland sauces. I was surprised, because I had experienced better food on recent international flights."

Pros: "Incredible service, great entertainment options, comfy seats"

Pros: "My flying experience with Delta was and has always been great. Always professional and courteous crew and employees."

Pros: "Small plane and a short flight, so just snacks and wifi, which was expected and was just fine with us. Crew was great."

Pros: "The plane had a ton of room."
Cons: "Then our connecting flight had extremely rude crew members who made us feel as though our experience was less important than the “sky members”. Super HOT on the plane as well."

Pros: "Staff is friendly and helpful"

Pros: "Everything was great, flight attendants were awesome"
Cons: "Nothing"

Pros: "Good customer service"

Pros: "Friendly crew."
Cons: "Minimal leg room; seat didn’t decline, delayed by 40 minutes."

Pros: "Crew was friendly and helpful. Flight smooth and quick."
Cons: "Gate change and departure time change not reflected properly on boarding pass. Problems with gogo in Flight."

Cons: "Sandwich for dinner"

Pros: "Great trips notifications"

Cons: "Every flight was 100% full. Inadequate overhead space. I felt I was being herded like cattle. It is NOT a pleasurable experience flying with Delta."

Cons: "I liked it all"

Pros: "The boarding agents were especially helpful and friendly to my disabled wife, travelling in a wheelchair."

Pros: "The staff are fun and friendly. One of the hostesses stepped into the vacant seat where I was sitting and stepped back further when people where pushing by. We were almost cheek to cheek. The closest I've come to a cute bum in years."
Cons: "The gratis food offering isn't healthy - those bread pretzels, versus the almond & tomato juice I had on the next flight, with ...can't remember the name."

Pros: "My Delta flight was a code share with Virgin Atlantic. A pleasant flight overall with my first impression being an airline with current popular music playing in the background and flight attendants cheerful. Since I was traveling alone, I opted to not purchase my seat prior to my flight date, instead I chose my aisle seat within 24 hours for free. I checked in my one bag and found out I had pre-checked so my security check went so smooth at the new terminal 2 at LAX. Looking forward to my flight back on June 15."
Cons: "Had a toddler behind me crying and screaming the last 40 minutes of landing into Heathrow because she couldn't sit on her mother's lap and made it quite unbareable for all of us in the vicinity. Wondering if there was an alternative way to handle the situation."

Pros: "Individual screens and earbuds for sale."

Cons: "Waited on tarmac at Laguardia more than 45 minutes after landing for gate to open up."

Pros: "Free food for all on this flight! Turkey sandwich was actually quite good! Great legroom, flight attendants, and pilot. Free great movie for all."

Pros: "Everything was smooth from start to finish, and the flight landed 10 min. early! Can't ask for more!"

Cons: "Amazing"

Cons: "Ended up stuck at Laguardia for 9 hours, tried to get onto earlier flight and wasn't able to because as I arrived as the jet bridge door was closing. The delta crew was pleasant, but I sat at the terminal watching to see how quickly that plane would back out to depart.... it sat there for another 45 mins, while I sat there wishing I was on it. My later/original flight ended up being delayed multiple times (not due to weather) and given no explanation for why."

Pros: "Seamless uneventful flight."

Cons: "Very crowded plane."

Pros: "Crew was efficient and helpful. Captain kept us posted along the way. They also keep air flowing when we were delayed to take off so everyone is comfortable inside the crowded cabin."
Cons: "Crew should try to wake me up for meals. Luckily my fellow passengers did. Otherwise I would have missed all my meals."

Pros: "Crew was very accommodating in light of the maintenance delay. Especially for those of us with small children."
Cons: "Look, delays suck. We fly about only once a year, and we ALWAYS have a delay. ALWAYS. Air traffic control at Newark will delay a flight for a hangnail."

Pros: "Emergency exit"
Cons: "Extra blankets as emergency exit is terribly cold Boarding"

Cons: "arrived 24 hours late. had to stay overnight in Newark. And United lost our luggage. The worst trip I have ever had."

Pros: "Good flight, decent crew. Food was okay."
Cons: "My entertainment set didn't work because the headphone jack was broken so that was a major bummer."

Pros: "Crew was great. Let me sleep and was pleasant and professional."
Cons: "food"

Pros: "Very friendly crew."
Cons: "This is a small airplane. I would like to see United insist that people check large bags."

Pros: "Fast boarding and helpful crew."
Cons: "Food was cold and soggy."

Pros: "The food was very good. The crew was very pleasant and accommodating. A bit late leaving but time was made up in flight. All in all a pleasant trip."
Cons: "Some of the entertainment screens were inoperative. The occupied light for the forward restroom (in business class) was not working so you never knew if it was free or not."

Cons: "the stewardess and steward bumped seated me continually when I complained she told me it was tight inexcusable"

Pros: "On time departure and arrival and a friendly crew helped keep this flight smooth despite some turbulence. The fact that there have been electrical outlets on this route for so long is a testimony to the Continental heritage."
Cons: "The seats in economy are just so tight that sleep on this short overnight flight was almost impossible. The lack of more recline (as in the recarro sears used on the LH/LX products) and short pitch make it hard to either work or sleep. The small plane size makes this sardine feeling worse and slows service to the rear of be craft."

Pros: "It’s existance. Informative capt."
Cons: "Late almost 3 hours. Sketchy bev service. 50 seat RJ."

Pros: "Nothing"
Cons: "Flight got cancelled again and again then call customer service but he doesn’t know anything about information. Totally ruined my day"

Cons: "3 hour mechanical delay"

Pros: "An early departure!"

Pros: "Pretty smooth despite high winds and on time."

Pros: "Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport"
Cons: "My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me."

Cons: "I only made it as far as Chicago, and my bag was fairly comprehensively lost as I did so"

Cons: "Person at ticket counter was rude did not want to wait in us when we was 1st in line. Did not greet and say good morning"

Pros: "AT THE TERMINAL IN PORTLAND THE ATTENDANTS WERE SUPER HELPFUL AS I WAS CONFUSED ABOUT GETTING MY TICKETS."
Cons: "JUST BEFORE BOARDING THOSE OF US PASSENGERS NOT ALREADY BOARDED WERE TOLD WE COULD NOT BRING OUR CARRY ONS WITH US AS THERE WAS NOT ENOUGH SPACE TO STOW THEM OVERHEAD. SO WE WERE TOLD TO SEND THEM DIRECTLY TO OUR FINAL DESTINATION. WHEN I BOARDED THE PLANE I COUNTED 7 OVERHEAD STORAGE BINS ON THE OPPOSITE SIDE TO MY AISLE WHERE I WAS SEATED WERE NOT FILLED AND THERE WERE SEVERAL SUCH BINS ON MY SIDE OF THE AISLE (I DID NOT HAVE TIME TO COUNT THEM BEFORE I SAT DOWN). I ASKED AN ATTENDANT WHY THIS WAS SO GIVEN WE WERE TOLD THE BINS WERE FILLED JUST AS WE BOARDING FROM THE DEPARTURE AREA. SHE WAS POLITE AND SAID SHE WASN'T SURE ABOUT WHO MADE THE ANNOUNCEMENT IN THE TERMINAL BUT THAT IN ANY EVENT MY CARRY ON WOULD ARRIVE SAFE AND SOUND IN VANCOUVER - IT DID BUT WITH MY BOOK FOOD SNACK WHICH i HAD INTENDED TO USE WHILE ON MY WAY TO CHI. AND VAN."

Pros: "First time first class flyer. It was great!"
Cons: "Being separated from my wife in seating when we booked before others that we talked to!"

Pros: "The flight attendants. Especially Meagan and Heather. Amber was a,sweetheart too. I had the same attendants 3 out of 4 of my flights that weekend. So cool. When they realized it was me again they spoiled me rotten. So good I feel like unless I have those 3 as my attendants I won't fly United again"

Cons: "Really awful, disorganized and unapologetic."

Pros: "Got through sucurity ar PNR barely in time to make flight."
Cons: "Even though I am a frequent flyer with a Global Access card, I was select for enhanced security check. I paid for the Global Accessmcard especially sofas to avoid this. United said it was a TSA thing while TSA said it was at the prerogative of the airline. Why did this happen? So much for TSA Pre or Global Access."

Pros: "The check in with united was rather disappointing. The staff working with united were not clear with instructions and rather rude. Checking in can be a rather stressful process when there are long lines and tons of people.... this person was just short, unclear and rude."
Cons: "Please see above"

Pros: "Usual United Corp mentality Overbook flites change your itinary leave you stranded with no connection spend nite in airport"
Cons: "See above"

Pros: "Arrived early"
Cons: "The plane dropped during decent."

Pros: "4"
Cons: "4 hours late, bad food, stressed staff."

Pros: "Flight did not happen"

Pros: "Not a single thing!"
Cons: "Arrived late"

Cons: "Kayak did not provide me with confirming email for flight in either direction and I missed my first flight to LA from Portland This is the second time I was not contacted via email from Kayak on flight reservations"

Pros: "nothing"
Cons: "it took me three days to get home. the first plane had a mechanical error. the second flight united booked me on was over booked so i didnt get a seat. the third flight they tried to send me on was also over booked. luckily someone volunteered to give up their seat."

Pros: "We stood in line forever to then be told the clerk couldn't ch we ck us in. When we tried the kiosk it didn’t work. Long story short we missed our flight due to their poor organization of the line and crowd."

Cons: "Seating next to the bathroom is gross"

Pros: "Friendly and polite! Crew."
Cons: "Middle seat. Space too small."

Pros: "Couldn't really figure out your Wi-Fi system so I just read a book"
Cons: "It's not really easy to set up your Wi-Fi system through the United app"

Pros: "It use to be, I could put up with the lack of comfort and services because the cost savings made it bearable. But thes days, the basic ticket costs are high and increasing despite ala Carter pricing. The flights are always full and the number of flights are down. Airline profits are at a peak yet very little is flowing back to improve the flying experience."

Cons: "No agent to check in when I arrived at airport. Only at gate. No advance check in or advance seating. Allowed passengers to have more than 2 bags. Flight was late. No help getting to next gate or holding aircraft. Absolutely uncomfortable sitting."

Pros: "That I got a refund, although that should be a given"
Cons: "Had to purchase new flight day of, as I was told of flight cancellation 5 hours before leaving to the airport. I then had to spend $500 on a new flight, and one of the connections refused to let me on the plane. Stil not home."

Pros: "Pleasant crew"

Cons: "Crew members were not helpful."

Pros: "made good time."
Cons: "they lost our luggage on the way back,Didn't make it to Portland. But it was brought to our house at 7:45. I think for 1600.00 for tickets you should provide pretzels. That would be great. Thanks"

Cons: "Canceled flight, booked me an impossible connection, put on stayby when I get the tickets months in advance. Offered no vouchers and made me fly out on a diffrent day. Hs aircraft delays on all flights"

Pros: "Nothing."
Cons: "Never flying United again. On my way to the airport in Portland I got a text from United that my flight to Newark had been cancelled and there was no way to fly me out of Portland to San Diego that day. My sister had to drive me to Boston so I could catch a flight to San Francisco, which took 6.5 hours because it flew over most of Canada for some reason AND had three babies that cried from start to finish. Oh and because I was a late addition, I had a middle seat. The second I turned my phone on after we landed I had another yet another text from United saying that my connection to San Diego had been delayed three hours and wouldn't take off until 11:15 pm."

Cons: "Cancelled and rebooked on a different airline with a long layover."

Cons: "Tried to get assistance at the United desk where my gate was located at and they could not answer any of my questions and would not assist me or many others who had the same issues."

Pros: "Nothing"
Cons: "Payed to upgrade seat was not comfortable and person next to me kept moving onto my side. Flight was 2 hours late so I missed my connection and had a terrible time to find a flight home. United staff was not helpful and kept telling me to go somewhere else for help. No food was served only tiny packet of way too spicy pretzels. Sat on the runway for an hour. Flight crew said 15 min and it was much longer. Crew seemed to be really confused."
