I'm thinking of booking a flight LGA -> YUL -> Germany with a 1hr 15 minute stopover at YUL. Air Canada LGA -> YUL, Lufthansa YUL ->. Germany. Flight is on the same PNR, booked via United.

is 1hr 15 minutes sufficient? I do have Global Entry if it helps. I don't know if Air Canada will check the baggage through to Lufthansa, or whether I have to move it myself (which would almost certainly make 1hr 15 minutes insufficient).

Alternatively, there is another flight, PHL -> YUL with a 2:55 stopover at YUL. (less convenient for various other reasons, but that much time should be sufficient, right?

Thanks for any comments.
