Airline reviews

Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."

Pros: "Good experience"
Cons: "Better snacks"

Pros: "Quickly moving through the airport."
Cons: "Take out old planes. It was really run down."

Pros: "Delta crews are very friendly and helpful. Seats are 'good' on the E175 plane - better than the cramped CRJ200 on some other short flights. We boarded early, left a little early and arrived early. Nothing to complain about, except maybe a crying baby behind me, but that's not Delta's fault. :)"

Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."

Pros: "Entertainment was awesome. Although airlines are stingy with snacks, Delta had a good overall selection and very generous."
Cons: "Something that cant be changed overnight, however, there should be a little more Aisle space for folks pass through as my shoulder was getting beat up after every passing person and cart."

Pros: "Crew was friendly."
Cons: "Wish the seat was more comfortable. Landing was jittery and bumpy."

Pros: "The flight attendant from IAD to MSP called Bernadette was wonderful!"

Cons: "Delayed"

Pros: "Super comfortable seats. Lots of movie options."
Cons: "Food was not very good"

Pros: "Flight was smooth, arrived early..crew was prompt and courteous."

Pros: "The food and the treatment"

Pros: "Crew and entertainment options were great."
Cons: "Cabin was very loud, with jet engine noise. Could not block it out. Seats were not comfortable."

Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Cons: "staff wasn't very friendly"

Pros: "The last time we flew Delta, we were underwhelmed. Our flight was delayed several hours and there was nothing exceptional about it when it did finally leave. That was 5 years ago, and there's been a lot of changes. There I'd now in-flight entertainment, reasonably comfortable seats, and everything was on time."
Cons: "Virtually no food options."

Pros: "Fly attenden alwas with a beautiful smile"

Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."

Cons: "2 1.5 hour delays for things that Delta messed up"

Pros: "comfortable seats in comf+ but no pillow or blanket for 4 hr red eye? Come on delta"
Cons: "Gate agent was the worst in two years..never smiled, never thanked anyone and didnt call me by name or recognize my diamond status. Boarding was a fiasco with the pillars in too small of a gate. FA had too much coffee they kept main babin lights on way too long and kept loudly asking if anyone wanted extra drinks snacks....this is a redeye, people want to sleep!!"

Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Cons: "Tv"

Pros: "The chekc in person was very helpful."
Cons: "The plane was too hot and the pilot did not accommodate the passengers request. More than just me made the same request."

Pros: "That I landed safely"
Cons: "1st class was horrible."

Pros: "I was able to pass the time with ease. A+++ in flight experiences. Great airline staff and awesome food."
Cons: "No complaints whatsoever."

Cons: "I have traveled with my luggage plenty of times through airports and the flight from washington to jacksonville, my luggage came back to me cracked and broken. I was surprised that Delta handling was worse than any of the cheaper flights I normally take and will not be checking any baggage with Delta again."

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

Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"

Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."

Pros: "My flight was canceled but Delta rebooked me on a flight leaving at about the same time as my original flight, which arrived just a little later than originally anticipated"
Cons: "My original flight was canceled"

Cons: "Delayed two hours"

Pros: "Got to my placs"
Cons: "Lol put the two fattest people next to each other"

Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"

Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."

Cons: "There delay"

Pros: "The crews were very friendly and everything went as planned. It was a nice flight."

Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."

Pros: "We did eventually get there"
Cons: "What should have been a 90 minute flight took over 4 hours! Between mechanical failure, overbooking and waiting for gates and sky bridges we missed our connection. Then when they rebooked our connection on a British Airways flight, BA couldn't pull up the tickets and we wasted yet another hour while Virgin Atlantic and Delta both passed the buck as to who was responsible for correcting it so we could get on our rebooked flight, which we BARELY did with only 2 minutes to spare!"

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

Cons: "paying extra for leg room and checked bags"

Pros: "Smooth flight and always a plus to see a beautiful smile throughout the trip from our Flight Attendant Stefany!"

Pros: "The crew were very friendly; service was good Trip was pleasant Plane was clean and comfortable."

Cons: "Delta cancelled the flight after midnight on Friday morning, and never rebooked me. I still haven't heard from them. In not even sure why I'm getting alerts about baggage claim."

Pros: "staff was very good."
Cons: "The flight was bought through Virgin Australia and without much notice, the flight was switched to Delta. The seats were amply smaller, amentities were not good (blankets and pillows). Food was terrible and was not as promised when the purchase was made through Virgin. Seats were so bad that my back and butt hurt after a couple hours. I would rather pay a couple hundred dollars more to have a quality flight experience."

Pros: "Nothing"
Cons: "Being scammed by the Chinese, China Southern"

Pros: "Smooth flight, fairly comfortable seats in economy with adequate legroom (and I have long legs), flight attendants actually smile and are polite."

Cons: "First class seats were uncomfortable for a 6.5 hour overnight flight."

Pros: "I am 6'6" 300 pounds ... So I regularly book first class for trips over 2 hours in length ... Delta remains my #1 choice for both value and overall experience in first class. The difference between Delta and all other domestic carriers is just overwhelming. United and American/US Air could learn a lot from Delta. I could have flown this trip direct on United, but chose to fly through Atlanta on Delta for less money and a better experience from the baggage check to the gate to the in-flight experience."

Pros: "Everything"
Cons: "Nothing"

Cons: "Worst shittiest experience! Delayed by 3 hours"

Cons: "The flight was canceled and was given another longer flight and had to pay for the luggage twice. Totally disappointed."

Cons: "Ok"

Pros: "Excellent customer service"

Pros: "Crew, leg room, and entertainment."
Cons: "We had to be redirected because the plane's instrument landing system (ILS) failed. We were redirected to another airport where they had to make repairs and then fly back from Geneva to Zürich Switzerland. It made for a very long flight."

Pros: "No e service"
Cons: "Food was not included entertainment was not include at that price"

Pros: "Rebooked me a nonstop flight to my destination!"
Cons: "Delays. O'Hare. United. Storms and air traffic control. Looking all across the board, it didn't look like anyone was leaving Chicago anytime soon."

Cons: "loudspeaker was way too loud - my hearing was fine before the flight...."

Pros: "I was returning from an international flight, and had carried my smallish rollerboard +1 personal bag all through (including outbound) with no problems. Just on the last leg, IAD to RDU, the gate agent forced me to check the bag, even though the flight was not full, and the bag could easily fit in the overhead bin. I was in Group 3."
Cons: "Forced to gate check rollerboard for no reason."

Pros: "every seat come with tV"
Cons: "Disappointed that few come with closed caption. Lousy choice of menu"

Cons: "Extremely noisy inside the smaller jets. Can't hear anyone or anything."

Pros: "My daughter was given assistance when needed."

Pros: "No delays, everything went smooth"

Cons: "I bought tickets for a Lufthansa flight with a Lufthansa flight number and confirmation notice, only to wait in line to find that it was a United flight and United didn't list the baby's ticket number that was in the Lufthansa confirmation! lost an hour resolving ticket issues. When I pay for Lufthansa tickets, I expect to have a Lufthansa flight with their great service."

Pros: "Did a good job of keeping us hydrated during the flight"
Cons: "The seltzer water is plain not lemon flavored as advertised in the magazine"

Pros: "nothing"
Cons: "1. Delayed flights- I took a round trip SFO-IAD. Both my flights were delayed by 3 hours each. Reached my destination at odd hours and was never compensated. 2. Not apologetic !"

Pros: "Nothing"
Cons: "Flight delayed in Washington, then after we boarded sat on a hot plane for an hour while flight crew did "training". United never apologises for delaying flights, seems like they don't care for the customers at all."

Pros: "Ease of purchasing ticket online"
Cons: "The $230 change fee for a ticket that cost me $70. No recourse but to lose the money completely."

Pros: "The flight was on time and everything ran smoothly."
Cons: "N/A"

Cons: "This flight was cancelled and it became one of the most chaotic ordeals to get from Newark to Seattle."

Cons: "Late full lounge bad food"

Pros: "Crew was great and accommodating due to hour delay"
Cons: "Late delay. Slow boarding. Sat on plane for hour before actual take off."

Cons: "It is outrageous that those seats and that legroom is legal. Something has to change!"

Cons: "Flight was delayed 3 hours. In 15 minute increments so we kept thinking we were leaving and then it kept getting delayed. Almost missed my brother's graduation from basic training. Not pleased. I would like some kind of compensation for this. Also I am flying back now and my flights have been very delayed and I will arrive at least seven hours later than planned."

Pros: "I didn't like anything. The only positive was the polite crew . The flight was terrible. The conditions was very bad."
Cons: "Bad conditions. Bad flight. Delayed and the airport is terrible . Thank you for the safe flight. But please upgrade the services"

Pros: "Dirty, tired airplane. This (and every other flight going out around our gate) was "oversold"- egging travelers to give up their seats"

Pros: "On time, happy and efficient crew."
Cons: "No food, but beverages offered, understandable due to the quick flight."

Cons: "Gate crew was rude and I'm helping boarding process was terrible unorganized chaotic snacks were terrible only soda for drinks seats were terrible hard cramped no leg room very poor conditions no entertainment onboard systems did not work crew on board complaining about United Airlines"

Cons: "Late departure."

Cons: "Besides taking off late, the worst part was the new seats are the smallest ever. I could not sit without my knees jammed into the seat in front of me, and on both legs, Ithe seats were narrow that the people next to me and I were overlapping shoulders - that was a first. Unless its flights in the future are significantly advantageous, United's losing my business. It's not worth saving a few bucks to me to be so uncomfortable."

Pros: "Ground and flight crew were all pleasant and professional"
Cons: "This flight is always fully booked - book your seat early if you can."

Pros: "Very comfortable plane. 2 seats on a side, 5 thumbs up."

Pros: "Great and on t time"

Pros: "Never got on"
Cons: "Never had a chance to find out if I would like it or not."

Pros: "Flight departed and arrived on time. Flight attendants were courteous. Boarding was quick."

Pros: "Everything went smooth and on time"

Pros: "Everything"
Cons: "None"

Cons: "Service"

Pros: "I loved how quickly we departed and arrived at each destination!"
Cons: "The boarding process was terrible. People forgetting to even stand in line for their boarding groups getting to cut ahead of those whose group is currently in the process of boarding. That should not be allowed. It's rude and disrespectful to other passengers/customers."

Cons: "Maintenance delays and rerouting caused me to miss my reserved ground transit in LA... United claimed on the phone I would be reimbursed for a taxi, but changed their mind when I sent them a receipt a few days later."

Pros: "same comments as above"
Cons: "same comments as above"

Cons: "Tight aisle"

Pros: "I love United. They're now my go to airline. I love the pet friendliness as well as every employee through United I met today from the bdl check in crew , to especially the flight crew on flight558 iAd to phx who I believe was from Houston and their Texas roots truly shined. Every crew member was Sooo attentive professional Cleanly pleasant and always smiling and happy to come around. Other crews could learn from this crew please take notice !!! I have never been so impressed (and I am a frequent flyer )"
Cons: "Flight tracker wouldn't work on screen or on phone disappointing"

Pros: "Blanket for lap"
Cons: "No service /selections. Paid for movie and fat child continually shut off TV w his fat arm on my armrest Boarding is very poor no assists as flight attendants virtually unattentive LAX dirty disgusting and no shops seating or restaurants No mvmt to allow stiff swollen legs all cramped in tiny seats. I pay bag fees while others get free checked bags at the gates. Many people are able to carry huge extra backpacks w no enforcement from staff Slows the whole trip down"

Pros: "Due to my late connecting flight I almost missed this flight. Thankfully they waited at the gate for me and the other people who almost missed it."
Cons: "My seat wouldn't lean back at all."

Pros: "Fast, friendly, on time"
