Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

they made me check my carryon. There was space in the overhead bins.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

The flight I was connecting with waited for me even though my 1st flight was late. I really appreciated that.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

There was no entertainment at our seats. The flight was comfortable and we had leg room. The snack we had was really good.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

The original connecting flight from Vancouver to Portland was canceled and then delayed. I ended up waiting for almost seven hours instead of three.

My flight has been canceled and I had to cancel entire trip.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

There was no food on this flight. We had less than 1/3 full plane and were not allowed to spread out. Staff gave the story of the plane had to have all of us up front for 'balance.' Total bs.

There were changes to my flight with many email and very difficult to keep up with details of changes. I consulted Air Canada website that said I was to depart Casablanca at 9:35 but when I got to airport that take off time was delayed by 2 hours. That's 2 hours at an airport instead of bed. I don't understand why Air Canada website didn't show the change in take off like they showed the change in transfer. Do better.

I was delayed from Montreal to Tokyo for 3 hours and they didn't compensate anything

Flying Business on Air Canada is wonderful. With ultimate destination in US, you get the Lounge. Only problem is there was no lounge in YQB so it had to wait until connector in YUL. Flight itself is only about 30 min like the old DC-NYC shuttle so there was no service other than almonds and the bottle of water that was at your seat upon boarding. Would have been nice to be offered a beverage and there was enough time to do a quick pass for the 16 seats. That and having a lounge in YQB are only complaints, but that's very first world complaint. The FA were cordial and professional if not warm. It was a good flight and I'd do it again. But, word to the wise, it's a very different experience doing border check in YUL than YYZ. Long walk and had to go through full screening (including taking off shoes and having to chuck the bottle I had just gotten not knowing there was going to be a frull screening since there was no warning) at YUL even though never left the terminal after landing. YYZ was just a passport check. This is not A/C's fault, but travelers should be advised/warned in advance so they know what to expect especially since you land and have access tot eh terminal and it's stores and food before you get to border check. If you have mobility issues, the distance can easily be a problem and there is no warning of how long it is until you have reached the end. My mom would not be able to navigate it and someone like her may not be able to stop in the middle of an empty long corridor to ask for mobility help. A sign offering how long (10 Min, etc.) the walk is like at new LGA terminals goes a long way. Also can be stressful if you're tight on time for a connection.
