I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

They canceled our flight and left us stranded to figure it out

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

Packed commercial flight was as comfortable as can be expected

My seat was very worn. Otherwise I had an excellent flight

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

It was good but I wished if they could have sign do not disturb if we did not wanted any meals . I was tired and slept through the entire flight and woke up just before landing .being hungry Too late to ask for something to eat before exiting the flight . Left feeling hunger 🙁

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

3 hr delay. No water given while on the plane for 3hrs.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

Flight attendant kept banging her cart into my aisle seat. Hard. Couldn’t lean seat back. Should be warned of limitations when booking seat

I will travel by BA only in future also. Only suggestion is they should give aisle seat in front near washroom for senior citizens
