They canceled the flight on us very close to the flight date .

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.

Flew SEA-CA, then CA-NRT. First flight was short but very uncomfortable, dirty, and had very small overhead storage space. The seats and fans were not cleaned and had visible dirt on them. Second flight was perfect.

My second flight ended up being through United and it was fine. Again, just frustrating that it was so late.

Everything went smoothly and as expected. We were on time and one flight arrived early.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Glad to see the staff of Air Canada take preference in protecting their customers from unruly passengers before they board. Well done

I appreciate the fact that the flight took off and landed on time What I didn’t like they never offer a snack eg nuts/cookies/chips

This website did not advise the prices were in $USD, when the flyer (me) was flying within Canada only and only a Canadian resident, and booking this flight in Canada. Furthermore, the area to board the plane was unusually hot and sweaty.
