Understand the check-in details at International airports

In response to the relaxation of travel restrictions and the opening of formerly closed borders throughout the world, online check-in is been launched for some international flights.

When should visitors arrive?

The check-in time for your international flight will vary depending on the airline you are taking. On some flights, check-in closes 90 minutes prior to the planned departure time. Others are permitted to arrive one hundred twenty minutes early. If you are travelling internationally, you should check in in advance and allow plenty time for security screenings and immigration processes. Please keep in mind that unplanned delays can occur at any time, but especially during peak travel hours, when planning your travel.
After this period, check-in and the bag drop will no longer be possible. Allow yourself ample time to arrive well before the appointed time.
