The plane is old. There was water dripping fown from the air cooling system. The toilets were mot that clean

The meal tray was not usable it was completely uneven

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

The flight was mostly smooth and direct (although it was 2 hours late). The glow of the flight attendant’s phone was annoying as I tried to sleep on this midnight flight.

Everything about this flight was good except for the very end when I reached my destination. Everyone from the tune to the wheelchair escorts were great with the case were great but I miss you with people at the check in this at the very end. I need help from the chicken desk because I forgot my pillow on the plane The female worker at the chicken desk said that they found my pillow and she was going to retrieve it for me. She left a 30 minutes without any update and her so she saw me walking back and forth waiting for her and they didn't even bother calling her or radioing her for any updates. They were busy because they were behind schedule and they were overwhelmed but thanks because at least glanced me and try to give me an update just a quick radio check or phone call. I don't care about the pillow but if you tell me to wait, I waited for at least half an hour before I said something and I just left because they wouldn't bother talking to me so I could, so everything's going in the review. I took pictures of the two men that were left working at the check-in counter. The totally ignored me despite the signals I've been giving them. I don't see any offers in the kayak review to add pictures or screenshots so I'm going to post another review I don't know their name but I'm pretty sure Delta will find other names when they see the review. Google with pictures. There was another guy at the chicken counter bring an orange workers vest who finally left after telling me that the girl that was retrieving my pillow is working the gates now. That would have been if they just told me that's what happened. But I had no update. Make me wait for nothing. Thank you Delta airlines!

Crew was real good, flight was smooth and came in early.

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.

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

It was ok. Jet was ok but it lacked many convinces we have experienced on other airlines such as in seat entertainment. Space seamed more compact than other airlines. They did not provide the gate to gate assistance we arranged for for our mom who needed a wheel chair.

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

West Jet flight was cancelled and I was not notified. I found out when I tried to check in on-line. Spent 4 hours on the phone with West Jet and Just Fly trying to figure what happened.

We didn’t make the flight due to Delta’s check in line moving too slow.

Flight was delayed 3 times. Then cancelled due to pilot being timed out. They refused hotel vouchers. Gate attendants were very rude and could not help you at all.

Flight was on time. Online check in capabilities made things quick and easy. Zone boarding was enforced, which I appreciate. Everyone was not lining up ahead of their zone being called. Crew was professional and friendly.

The big lady was sitting right next to me and the button to recline my seat was blocked by her huge arm. No power outlet for chargers. No inflight Wi-Fi movies

Flight was delayed four hours! No on board entertainment fir a four flight. Minimal food

20+imite delay on the plane with no air. Part of our group had no seats assigned and took a long time to get fixed. Again no wifi and snacks were sad

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

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.

It was a small plane and difficult to put my carry-on bag in the overhead compartment. The crew was awesome and boarding was good.

Both legs of my flight were delayed and my luggage did not arrive at my destination. It was a very frustrating experience.

Flight from Toronto to Calgary was >2 hours late departing and was overbooked

The plane was two hours late and we got bumped. Instead of getting to our cruise ship at 10:30am it was 09:30pm. We also got bumped to Edmonton instead of Vancouver.

I like the friendliness of the crew. It could have been better being more on time. The flight from Detroit to Toronto was delayed two hours.

One flight was cancelled and air Canada rebooked new flight immediately for me. Checkin was awful at Detroit metro airport. No clear signage, I was directed to wrong line and found out after 15 minutes of waiting. Air Canada line was extremely long with limited checkin counters moving very slowly.

Have your eTA ready, printed or on your phone. They fo check it although it is tied to your passport

My 0600a flight was cancelled and I was notified the night before. It was cancelled due to another plane and its technical difficulties. I appreciate they had me booked on another flight and the customer service was excellent, but the switch was for 1:00p and that ruined an entire day of my vacation. Instead of arriving at 1015 I got in at 5:45.
