I only wished they had tv monitors. The flight and the crew were excellent!

Make sure to check the airline delay flights rate and if you have important commitments choose another airline.
JoshuaFlew with Air CanadaYYZ-DENApr 2024
Toronto's customs was one of the faster experiences I've had. They opened four more lanes to expedite the process when the lane got too long, to ensure we would all get through within around 15 minutes. The public transportation within the city is also top notch, in my opinion.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

Internet on both flights was sketchy. Thus in flight entertainment was non- existent on MN - Balrimote leg.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

It took 30 minutes to check in with the Westjet rep. They didn’t have enough seats and she needed to make a call… I am always “randomly” selected to be checked at security. Their “randomly “ selection system may need some updating. They treat people like criminals. It is not appropriate behavior.

Found the seats very crowded—too close together ! And waited a long time for our luggage All staff at both ends were excellent!!!

Flight cancelled and Kayak switched our return flight to a red eye. Ridiculous.

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

Lost my luggage. Filed a report and there is no response. Received a phone call from another airline that said they had the bag and they did not know what to do with it

Very good over all , would have been nice to have entertainment on the flight

Absolutely the worst airline I have ever taken. They lost my baggage and told me my bag tags had been cancelled. When my bags arrived days later I had to pick them up at 3:15 am. My return flight was delayed another 6 hours and they broke my bag. Westjet does nothing to try and make it a better customer experience and all the customers services representatives I spoke with were useless and incompetent. Never flying westjet again.

Easy self checkin and baggage drop. No in seat entertainment, but wifi and app worked well

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

I paid for a comfort class seat and was seated in economy.

My plane was cancelled and had to be rebook for the evening was not happy.

The flight was cancelled and we had to rebook on Porter to make our cruise the next day. Air Canada has not compensated. We won’t be flying with them again. This is the second time this has happened. Also the return flight was delayed 2 hours who knows why.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline
