Flight got delayed But satisfied with the pricing of tickets

Flight was oversold. Seats assigned to multiple passengers. Delay 1 hour to sort out.

Good but I don’t received my bags yet is been 5days still no update

Flight cancelled. Major disruption to our travel. Do not use Air Canada from KC. To few flights.

Friendlier staff who are nice to the elderly who need assistance

Service was great. Flight was delayed an hour which made our connection very tight and stressful. But we fortunately made it.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

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.

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

Air Canada seems to be understaffed which caused delays at every point of the flight—delays at departure, delays in the air (circling), delay after landing, delays at the gate before disembarking. Horrible experience. And my son, who departed Toronto today, experienced delays because the passport scanning system was down and was told that he would not be able to board his flight. Toronto airport is a mess!!!!
