Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Too many oversized carryon baggage. If carrier reduced checked luggage fee this could be avoided. The staff were friendly and helpful, very professional.

Nice smooth flight with pleasant stewards. Slept most of the flight, they could have slowly turned on the lights to make it more pleasant. Otherwise a good trip.

Great! No food was available during the flight due to the catering service strike but snacks were given throughout the flight which was nice.

I wish that seats closer to the front of the plan were available, but when I booked the flight the seats were VERY expensive so I did not book seats at that time. The day before flying only seats at the back of the plane were available. It takes so long to board the plane and empty the plane on arrival due to SO many roller bags.

Crew was rude.didn’t even say hi or welcome to board

Good flight. No I’m seat entertainment. But my phone worked just fine on the west jet app.

Nothing special. Unacceptable wait for baggage on arriving in Calgary

Departure delay on a late night flight. Made us even later. Tired but got home.

Westjet forced me to put my carry-on baggage in check-in probably because I was assigned seat 23A (the last row seat), which had no cabin space, which is unfair. I wanted to carry on my luggage so that I don't have to wait at the airport for my luggage. Also, because there was no cabin space, I was forced to keep my laptop bag under the seat, which I didn't want to as I was carrying 2 laptops and charger. The airline should basically tell people that if you are assigned a last row seat, then you are not allowed a cabin baggage or a personal item.

Easy processing, flight time was quick and staff was professional and kind.

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

Food offerings need to be more plentiful and beverages need to be more healthy.

The crew suki/zuki is very rude. The zoning is only being announce once and there’s no way we will know what is currently allowed to board. I’m zone 5 (currently it was zone 3 but hich I didn’t know coz i went to the restroom). I saw a guy (zone 4) start boarding also. Then my husband (zone 5) started boarding also. But when it’s my turn, he said that i have to wait coz it’s still zone 3 and I questioned him why was my husband allowed when we are both zone 5 and i pointed to him my husband who’s boarding already and he told me to be attentive next time. And i told him he was so rude u like the other lady staff who is nice. The lady is the one who allowed the man (zone 4) and my husband to start boarding. There were 2 lines (the lady and suki)
