You can check in with Air Transat as early as 24 hours before your flight using the airline’s online check-in service. This feature is available for most domestic and international flights and closes 2 hours before departure. By checking in online, you can choose your seat, confirm your travel details, and receive a digital or printable boarding pass. This option is especially convenient for passengers traveling with only carry-on luggage, as it allows them to go straight to security without stopping at the check-in counter. For those who have checked baggage, online check-in still helps save time—after checking in online, you can proceed directly to the designated baggage drop counter at the airport. In addition to online check-in, Air Transat provides self-service kiosks at many airports, which open approximately 8 hours before the flight and close 75 minutes before departure. These kiosks allow travelers to print boarding passes and baggage tags, offering a fast and efficient check-in option. If you prefer to check in with assistance, airport check-in counters generally open 3 to 4 hours before your flight and close 45 to 60 minutes prior to departure, depending on whether it is a domestic or international flight. Boarding gates usually close 15 to 30 minutes before takeoff, so it is important to complete your check-in and arrive at the gate on time. Some passengers, such as those requiring special assistance or unaccompanied minors, may need to check in at the airport counter. Using the online check-in service as soon as it becomes available gives you a better chance of securing your preferred seat and reduces stress on the day of travel. Whether you choose online check-in, a self-service kiosk, or the traditional counter, Air Transat offers multiple check-in options to suit different travel needs. Checking in early not only speeds up the airport process but also enhances your overall travel experience.
