Delay after delay.......they are awful Delayed because of cold wx really!!!!! We live in Canada

My one complaint was that while we boarded using the standard enclosed gangway, when we arrived at SEATAC, the ground crew were slow to hook up the stairs. After reaching the tarmac we had to walk up a long ramp all outside in 35° weather. We just came from Bali and did not have warm weather clothes. This was in addition to having to collect our bags in Vancouver, take them through security again and then having to show our passports 4 more times all within the Air Canada section.

So we didn't actually go. We were hoping to go for the Inauguration of the first female president. When That Guy got elected, we bailed. Unfortunately, we got basically none of our money back, despite having travel insurance. Would not fly with Air Canada again unless I had to.

flight was delayed, there was open communication about the delay the delay pushed way past the posted delay time and

Ok Did not like that the second leg of flight was moved earlier making it a rush to make it

This was my first time flying on Air Canada and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

This was my first time and the experience was good and pleasant enough, great crew members and the price I paid was amazing,

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

Air Canada is not only the worst airline in the business but the worst business in history.
