The recommended arrival time is 3 hours before scheduled flight time. We advise you to arrive earlier to be able to pass at the check-in counter and deposit your luggage on time.
Kindly note that YUL Montréal-Trudeau International Airport is open 24 hours a day, 7 days a week. However, each airline sets its own hours of operation which is based by its flight schedule, therefore please contact your airline directly to determine how early you may check-in for a flight.
