If all gates in an airlines' designated international boarding area are full, passengers will board or deplane from the opposite international boarding area.
At times, aircraft have to wait until one of the two gates open up or passengers have to deplane on the tarmac via airstairs.
This allows passengers to deplane directly aboard and be carried to the main terminal.
Boarded passengers move with the plane until they are deplaned, which can occur individually in our variation.
