Flights are CNX to BKK to MUC (overnight in MUC) then MUC to YUL and on to YYZ. Would like to short check bags to YUL, clear customs then carry on bags to YYZ. Anyone have input to this approach? Have overnighted in MUC previously with no checked baggage issues but have not changed from checked to carry on in YUL. Would you have to clear security again in YUL? Thanks for any input or tips on this approach.
