Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

Overall, terrible. Flight from SFO was delayed due to “air traffic control issues”, and we were all mislead about connecting flights. Told “you have 20 minutes to catch your connection”. Reality was 5. We got to watch the plane sit at the bridge. Won’t fly Delta with a connection again.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

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

The seats are uncomfortable and there was no power to recharge a phone.

Forced to check my bag which fit in carry on, boarded and then sat for over an hour waiting to take off with no explanation.

Very good as always, stand out airline. The passengers whom choose to stuff baggage that otherwise should be checked-in is a real bother but that's not the airlines doing. A real frustration that passengers just don't want to check-in luggage. This is a pet hate unfortunately.

It’s a two prop flight so I had problems with my ears on re- entering ! But otherwise fine

I love flying with Qantas. There was no onscreen entertaining on this flight, and only a snack provided (not a meal) but still better than Jetstar or Virgin (in my opinion) so still happy.

Wheelchair assistance to move through the terminals and to/from the plane door was excellent. No vegan snack on the flight, only something with salami and cheese in it.

The old Plane had not been cleaned properly in a long time.

Planes was old - business class seats looked like they were installed in the 80s

Our baggage didn’t arrive with us on the plane. Need I say more?

I got upgraded from economy to business, and the experience was outstanding

I have taken this flight many times. It is ALWAYS late. Every time there is significant delay (1-3 hours) before boarding. It’s very consistent. Even after boarding the expected landing time was delayed twice. The seats are very narrow and cramped. Food is barely editable. Considering an economy ticket often costs about $2,000 it’s one of the worst services ever.

Boarding was over 3 hrs late and we didn’t land until almost 1:30am

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Liked nothing. As per previous segment it was delay delay delay.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Most disapointing experience. We were rerouted to Toronto, after a 7 hours flight , where we sat on the tarmac for a little over 4 hours, in a full airplain with no air. We were given a tiny cup of water twice during that wait. After the long wait we taxi out of toronto to wait another 30 min. Many people missed their conections including my kids and I. We were promised a hotel room in Montreal on the aircraft and at the exit of the aircraft, then directed to a desk after custom where me and my two kids were told that we do not get a room for the night and that we were on our own, after a back and fourth and stating what was told to us, the agent at the counter says that we are right and that we should have a room. I ask the lady if she could look into a different flight for us for the next day as I was with two you g kids and wanted them to get some rest. The gentlemen next to her jumps in and said there wss nothing without even (pretending) looking at their system, I insist and say that they could look for the kids. They seemed to have trouble with our reservation so they gave up. I told them that I needed to talk to a manager, they said there were no managers and that no one can do anything, to which I responded that there must be someone that could do something and that it does not make sense for them to repeat the same think as we are not undestanding each other. She threatns to call security and says I am rude. I say I will go, just give me the vouchers and ger response is “ not giving you the vouchers because you are rude”. I was not rude. It is normal to want to talk to a manager. I even said that the people at the counter were not resoonsible for the long journey and that there was nothing they could have done. But to threten and himiliate someone just because they ask for someone else to talk to ? I understand they are overwhelmed, but you know the quality and calibre of a company in the bad times not the smooth ones. I ended up leaving and paying for my own room and board.

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

The free snack options are pretty pitiful for a 2.40h flight.

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Good experience but the snacks are not gluten free, so I cannot eat them.

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Paid for a window and was assigned to a middle seat with 2 very large people on each side of me. Flight was sold out and I feel I need to be refunded foe paying for a window seat and being put in a middle one..

Promised lounge access, gate agent didn't allow us entry.

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

I have been flying with American most of my professional career. But the airline seems tired and becoming more and more subpar with older planes than other airlines, dirtier and less comfortable seating, and less and less amenities. Their WiFi seldom works and their food is becoming more and more mediocre. How do you fly from LAX to PHL with only being offered one drink and as a platinum customer. I am exploring delta here on out for more of my flying.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

a321 business class not up to transcontinental & international flight standards

I can't say as it was cancelled and rerouted to Toronto. I had an unexpected 10 hour layover there. A new delay every hour, Flights overbooked. Misinformation given from registration to help desks. A long exhausting day of travel on the way home.

Bug wouldn't let me upgrade my 17 year old son to an exit row preferred seat even though conditions clearly stipulated 16 years minimum. Luckily no one else took the seat so a supervisor was able to force quit my son at the gate. Could have been a real problem had we been separated but all is well that ended well.

Chicken or pasta, served in a heated plastic. Pure poison and lack of imagination. For vegetarian option, can you please skip stupid pasta?

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved

Very good. I liked that I could go through US customs in Montreal

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Had to wait to clean snow at end of ramp.

Good day, I would have like to be able to pay for upgrade once onboard. There was 2 empty seat side by side in first class on AC949 PTP-YUL on Feb.07, 2025. I ask the flight attendant if I could pay to upgrade in those seat but was told that I had to do it when I checked-in and was too late now. I said that Air Transat does offer to pay onboard when first class seat are available. Maybe something Air Canada could look into in order to increase income for the company and get a better client satisfaction. Sincerely, Michel Spinosa

Smooth on time flight with standard AC service. As usual food options awful. Wish airlines could offer better quality food services

Boarding could be improved, no need to wait after a previous group is completed
