Our flight was delayed by over 4 hours due to a maintenance issue. They announced a new plane was on the way. We were given a $12 food voucher ( airport food is quite expensive You can’t even by a water and a small snack for 12:00. 4 hours later we boarded and landed in Atlanta at 10:20 ish pm. Of course we missed our connection and we were given a hotel voucher and another food voucher ! We didn’t make it home until 11:00 the next day ! Unacceptable

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

Much better than I expected for such a long flight.

Good - better than other airlines in terms of food and seat comfort.

Experience was great. My only advice is to have a pasta dish on the menu. Otherwise everything was excellent.

Flight LA to Sydney was first moved earlier by 2 hrs from 10:25 pm to 8:25pm roughly a week before departure. Then on actual departure date, it was delayed 2x, and needed up leaving close to 10 pm. Then entertainment for the whole flight wasn’t working for most of the seats including ours. The baby crib at the middle isle was being taped to the wall to keep it tacked in using a packing tape while passengers were walking by looking for their seats. Not projecting good confidence. After a few minutes after take off the whole crib fell off. Good the people seating next to it wast hit or got scared. At arrival at Sydney, crew handed the customs forms as we were getting out of the plane. So passengers had to scramble to find a place to fill up the forms along the corridor going to immigration. So no one is available to help from Qantas to fill up the entry forms. Not a very good experience for a flagship carrier.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Smooth flight. As always dinner could have been more generous. Breakfast was great.

Moody attendants that can barely look up at the passengers. I’m all for people having an off day, but you can tell some Untied Airlines Employees have lost their zeal for their jobs

Great checkin experience and flight crew were very friendly and helpful

Staff did not care, and very clearly did not want to be serving passengers. Requests were ignored repeatedly. Toilets filthy. Bins were just trash bags hung around the place that were never emptied. It was a challenge to even get a glass of water on a 14 hour flight.

Got automatically assigned a middle seat, unless I fork out extra money for seat assigment.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

I was traveling alone abroad for the first time and the staff was not helpful and rude at times.

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

Baggage allowances are terrible and the experience of only being allowed one bag and paying so much to take sporting equipment to a known ski area should be addressed.

Bad food, small seats that didn’t recline. I thought I was buying a quantas ticket so I feel like I got scammed

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The food at Admirals Club was really great Pijamas were a nice feature The flight attendant was very nice and great attitude The aa.com does not work well specially internet service Overall a very good flight .

Flight a little late. Entertainment system didn’t work for first hour. Toilets dirty after 2 hours. Is there no one assigned to clean them?

Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.

Not enough electronic outlets for charging in the Air Canada waiting to board area but the Most important thing….the plane was booked to only 40% capacity and my row of 2 other seats were empty. My row happened to be one of the few rows that did NOT have raising arm rests. The flight attendant made effort to seat me in a different row. I needed wheelchair assistance due to a cyst on my knee and struggled to move from seat to seat to get to the row. Those 2 empty seats tormented me the entire 15+ hour flight as I had to be upright the entire flight and was not able to elevate my knee. Lots of other passengers were laying down due to the arm rest being able to retract. It is a shame that he couldn’t be gracious and find a row that I could move to.

Terrible. My brother broke his leg and couldn’t board the flight and air Canada couldn’t do anything about rescheduling his flight. Poor customer service and help all around

I Teall staff was great and helpful and communicated needs and special care for my granddaughters and family as well as others. Well done

Terrible experience! All flights delayed, staff had no idea of what they were doing, and at the end luggage lost for 2 days!

Flight delayed 3 times and also delayed again and by the time I reached Sydney, I couldn't get my Virgin Air as my flight was delayed and I was asked to contact here and there and asked to go to this and that terminal and was told there's no other flight as flights are all full to Melbourne. Thank God, at the very last minute, I was put into Qantas and didn't arrive till 7.30 pm in Melbourne instead of 2 pm. Will never use Air Canada again. Besides, the sittings is so tight and can hardly stretch a bit and eat without elbowing my side passengers. It was indeed a very uncomfortable flight.

Crew helped to find more comfortable seats for passengers. We never got tea or coffee on this trip even when we asked. Not even with breakfast.

Air Canada seems to be understaffed which caused delays at every point of the flight—delays at departure, delays in the air (circling), delay after landing, delays at the gate before disembarking. Horrible experience. And my son, who departed Toronto today, experienced delays because the passport scanning system was down and was told that he would not be able to board his flight. Toronto airport is a mess!!!!

I could feel the knees of the person behind me in my lower back for 15 1/2 hours. The. Seats were small and space was tight. People were nice. Coffee in the morning was in a small cup and half full and they never came around again.

THEY LOST MY BAGS. I WILL NOT GET THEM BACK FOR 2 WEEKS. everything was delayed. boarding, take off, everything. it was horrible. i am now without luggage for 2 weeks and they have offered me 0 compensation or help. i will NEVER fly air canada again and i suggest you don’t either <3
