Domestic and international flights form Air Transat can be checked in using the internet. The online check-in for the two forms can be done 24-hours to 3-hours before the expected departure time. Moreover, the online service is not available in some U.S. Airports, thus not recommended for passengers checking in through the U.S. Airports. Passengers willing to check in on the internet need to visit the Air Transat website and fill in their details such as name, address, flight number, date, and destination. Afterward, they can print a boarding pass or barcode to be used during the airport check-in. In addition, they have to put their Credit Card and pay for the excess check-in items. Customers with accessible mobility and other special passengers should check in at the airport.
