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!

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.

The seats very Uncomfortable, no meal and no entertainment for a 4Hours flight. Smooth Flight, Great Take off and landing. Superb crew!

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.

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

Trip was uneventful which is good. Boarding took a long time due to many disabled/elderly requiring assistance which again is fine. Landing and take off were excellent. Food and entertainment were as expected, bring your own if you have preferences otherwise you get what you get.

Okay but not like typical first or business class. On domestic airlines

Our seats that I had paid extra for near the front of the aircraft were no longer available on this replacement aircraft. We were told we either had to accept the new replacement seats in row 27 near the back in seats E and B, no longer together, or sit in the very back in row 30 squeezed into E and F seats that do not recline or have trays that provide a flat platform for a refreshment. This is not what I had expected. However, again your flight crew did the best they could given the circumstances.

We were delayed by 3 hours and the turbulence was rough, nothing younger control over

Same as my Tulsa to Chicago flight, this one was quick and professional.

When I booked the ticket it said that it was ANA and once I paid it changed to air Canada.

Boarding was delayed 50 minutes. The flight going to Chicago was canceled, causing lots of problems and causing me to rebook and miss an event. I was traveling with a colleague, and he was unable to get on the same flight after 40 minutes on the phone, which meant I had to wait for him after my arrival. My flight down was delayed an hour before take off, had to sit on the plane, then 30 minutes after landing to get to a gate. No real food, only juice/ water offered for the 3.5 hours on the plane. Not a good experience.

Check-in was a nightmare. Wouldn’t let us board with our dog even though he has flown on anir Canada before. Only one of us could go. Will never fly them again.

Flight got cancelled and didn't get another flight til late and almost missed the connection because so close. We are still waiting for the bags to arrive the next day.

Overpriced. Exploitative price gouging. Appreciated getting bumped up to a seat with more leg room though.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

The flight is very short, may be a little snack can be offered

They canceled my flight last minute, no hotel provided and they rescheduled Sunday night, hope they refunded some money
