A. Moving through the terminal

Getting from the terminal entrance to the boarding area can be a voyage in itself. Boarding areas may be far away. Many terminals publish maps of their interiors on their Web sites so you can chart your own course ahead of time.

There may be long lines at check-in counters and security checkpoints. If you can't stand for long periods, you can ask for an alternative such as a chair while you wait your turn. The terminal is also expected to provide seating in and between entrance and boarding areas for people who find it difficult to stand in lines or move around.

1. Finding help

Inside larger terminals, you will probably find a help desk near the entrance where you can get information and help. Some terminals may have automated information kiosks or information dispensers. These are expected to be usable by travellers with disabilities.

If you had arranged for a friend or family member to help you get through the terminal ahead of time, your transportation company will give your escort a temporary pass through secure zones.
