Potentially flying SFO-EWR-YUL-CDG on UA/AC with a 1:45 connection in YUL. Will be in J and have GE. I browsed this thread, but didn't see any recent posts. Is 1:45 enough to connect? It'll be a single ticket with luggage checked through. Is there an airside transfer in YUL, or do I have to collect bags, and enter Canada to make my onwards connection to CDG?
