My flight from Montreal to Vancouver was initially booked on AC 309 which was scheduled to fly on an Airbus A330. The A330 features the classic pod (which I have reviewed here) in a 1-1-1 configuration, similar to that of the 767. Few months before my flight, I was switched to AC 307. Although the flight timing is better (5pm instead of 7pm), I got downgraded to an A320. The A320 uses the domestic recliner seat instead of the full flat seat. I tried to change my flight to AC 311 which uses a Dreamliner but I had no luck even up to 1 week before travel.
