Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

Could not make the flight. No one would help us at all

Decent entertainment although my wife was not offered any ear buds so couldn’t enjoy. Real issue was the appalling food. Presentation was unacceptable with cheap hard to open packaged bread, plastic cheese again in hard to open shrink wrap, main course in small cardboard box again hard to open, wooden utensils which lack substance making the whole experience poor. Surprised I didn’t cover myself or neighbour as the food moved all over the place. Breakfast calzone was dry and unappealing with the staff basically throwing them around. Very disappointed

The pricing was split into an ultra basic fare with a comfort seat upgrade. This is misleading. Never were we shown an ultra basic fare. What this did because the fare category was ultra basic we could not bid on an upgrade first class seat. All e mails from WestJet were for ultra basic category with my wife and I upset as we could not confirm this with anyone from your firm.The check in counter were not going to allow our carry on but after some checking saw we had ultra basic and a comfort seat upgrade. They could not figure out how this was done. Now we have to go through this again at the gate in Mexico. Unless I missed it - please let customers know the billing in future. Respectfully. Gary & Nancy Moughtin

I wasn’t checked in for the third leg of my flight, my bag was checked through to Dublin but when I went to the gate in Toronto they said I wasn’t on the flight and had given my seat away. I had to wait 24 hours for another flight and instead on the one I had booked it was now 2 flights.

The agents at the Kelowna YLW airport were really grumpy. Same with oversized baggage person. Staff on the plane were great.

The delays were never ending and we were never properly informed as to why. 1st and 2nd delay were handled well, but by the time we received our 7th delay, and then subsequently asked to willingly get bumped, it turned into one of the worst flying situations of my life. I didn’t get home until 2am which is roughly 5 hours later than originally planned.

Great flight, great landing, nice staff. Our seats were a little cramped.

No food, water, snacks.”beverages”. This was on Christmas Day. Upgrading cost $100, for what exactly?

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Crew at gate and onboard were just very OK, not very friendly and honestly seemed bothered to be there. I will give a shout out to still selling headphones for those who forgot.

Flight Boarded and departed on time. The Flight crew was very friendly and accommodating. The aircraft was clean and free from clutter and debris. I will be happy to recommend Air Canada to my friends and relatives for their flight needs. They were very attentive and responsive to our needs as Senior citizens.

Everything. The crew was so friendly, helpful & smiled. We had an excellent flight getting in earlier.

Complimentary food options could be better. There should be a little wait between people boarding with children under 6 and the rest of the boarding. There isn’t enough time to get yourself situated before take off.

Got denied my flight was told on Google that Air Canada was supposed to book me a flight back home because I never was able to go to my destination. They did not help me whatsoever. I had to book a whole new flight for that reason I would write this is zero

The plane was delayed an hour. Heard from other passengers that the Vancouver connection to SFO was never on-time.

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.
