All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Couldn’t request a vegan meal somehow but I noticed other people getting them

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

Good food and entertainment options. Great Staff that were all welcoming and caregiving.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

There was a snafu with confirming seats at check which left us in limbo for the second leg of our trip. I believe the ANZ app is not well integrated with the systems at the terminal resulting in this disconcerting error.

Flight attendants are always pleasant and helpful. Pilot kept us updated.

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.

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.

The seat is too hard and my back and bottom are having servers pain

There was no lounge for passengers waiting before boarding the aircraft at F65, so passengers are just sitting on the floor or just spread everywhere the premises before boarding.

Great crew, friendly. Found the trip long just sitting with no onboard entertainment

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Cut off carry ons, had to check, got on and there was plenty of bin space. Disappointing.

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 .

Delayed 4 hours from Charlotte to Nashville. Could have driven there faster. Information provided by AA was sparse.

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?

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, soay e there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

American always delays flight so it stressful getting the next connection

On a 4.5 hour flight to Las Vegas there was no food/lunch provided only cookies and a drink. This airline is starting to look and act like Sprit/Frontier. Will start to look into other airlines to fly more comfortably

less delays; there was an hour+ delay on both flights. self serve check in kiosks weren't available for British Airways flights

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

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.

It was an enjoyable flight. I guess the airlines will never go back to catering, they save so much money.

Lovely staff for a short flight! Complimentary wine too made me happy.

5 delays to departure. Finally left 2 hours after scheduled time. Further issues with “paperwork” when we were ready to push away from the gate. Air Canada has a real problem with flights between Montreal and Toronto over the last 24 months. Of my 12 flights, 8 have been delayed or cancelled. With no compensation. I now drive between Toronto and Montreal whenever I can. At least I know I will get there when I planned to.

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

Terrible crew. Mediocre food. Terrible headphones. No Bluetooth connection for entertainment. Crying babies. Horrible experience.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Difficile quand le gate change, les deux fois. Quand on m'a changé les sièges que j' ai réservé, les deux fois. On m'a dit que j'allais être remboursé et rien eu encore

Air Canada continues to disappoint in almost every way. Probably the result of a monopoly, so NO need to improve anything

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

Everything was fine except that the ground personnel in Toronto wasn't able to operate the jet bridge, so that everybody was stuck in the plane after landing for 40 min, so I missed my connection.

J ai resté plus 5heures dans l attente du vol et je n'ai pas pu être à l'aise et le retards d'avion ça me dérange et c'était très dur journée pour moi malheureusement

They have more than 4 hours delay, and broken all my bags

FA’s were awesome, aircraft was beautiful inside and out. Best first class experience I’ve ever had.

I would be good to have more lead time between connecting flights. On the way into the country, there is always about 2 hours between landing at Munich and takeoff to Berlin. When leaving to return to the States, there is always only 45 - 50 minutes between landing and takeoff. This very stressful and I have missed a connecting flight home before. All it takes is for the first flight to be delayed for any reason and then you have chaos.

Very short flight so the limited space and lack of entertainment were no issue. Crew was friendly and the flight was very punctual. Baggage claim in Prague was lightning quick.
