We boarded 20 minutes before the actual boarding time. The plane left on time and arrived a little early. Air Canada's crew served 1 drink service during a 4.5 hour flight, with no snacks. It's a good thing that I have access to lounge service.

Considering I cancelled the flight 2 months ago -- I would have to say the communication was poor -- since I continue to received updates. I say poor since Kayak seems not to want to respond to me to reschedule a flight -- they hold my voucher -- so I can not do it on my own --
