I have a good friend who's flying (in AC on J) from DEN-YUL, then connecting to a flight on LH from YUL-FRA. The inbound is scheduled to land at YUL at 5:09pm, and the connection departs at 6pm.
That seems awfully tight to me - but I don't transit YUL that much. Thoughts? I'm assuming that OSS will help; will all AC inbounds be automatically cleared for OSS, or is there anything that my friend should (could) request on departure from DEN?
