I can't say as it was cancelled and rerouted to Toronto. I had an unexpected 10 hour layover there. A new delay every hour, Flights overbooked. Misinformation given from registration to help desks. A long exhausting day of travel on the way home.

I can't say as it was cancelled and rerouted to Toronto. I had an unexpected 10 hour layover there. A new delay every hour, Flights overbooked. Misinformation given from registration to help desks. A long exhausting day of travel on the way home.

Very Poor Even with the disruptions our flight was delayed twice then eventually cancelled. Subsequently we to this date have lost 3 days of our vacation. The situation still remains unresolved

Had to wait to clean snow at end of ramp.

My flight was delayed for more than 18 hours no accommodations was provided spent the night at the airport

Liked the lounge in Toronto. The filmed safety information featuring a tour of Canada was amusing, maybe confusing to those with out English or French, or flying for the first time. With a few exceptions, personnel were polite and helpful.

Horrible. Sat at the gate in the plane for 2.5hrs.

Planes were clean. Flights on time. Boarding very smooth. Flight attendants were great.

My screens didn't work on both my flights, while most of the cabin's did. Flights were OK, one took off over an hour late.

The seats for first class were so close together it was hard to get by one another to go to the bathroom. If I knew that this was first class I would have just paid and flown economy
