Question

Is Timatic the only database that airlines use to check documentation requirements for passengers?

Answer 1

There are two main systems used by airlines to check travel documentation requirements such as visas/etc.

The first of these is Timatic as you've mentioned. This is by far the most popular, and is used by most airlines.

The second is TravelDoc from ICTS which provides a similar service, but is less common.
