If you are checking bags or travelling in a group you should allow more time. Always consult your airline for check-in in desk and bag drop opening hours.

If you are flying soon, please be aware that it might be very busy at peak periods, so allow yourself plenty of time to check-in, go through Security screening and allow time to go through US Preclearance before your USA bound flight.
