Thinking about Using the non-US passport to travel domestically for a US citizen got me wondering.
Most large airports handle a mixture of domestic and international flights. These flights typically use the same parking stands and the same jet bridges, but passengers are discharged into different areas depending on where they have arrived from.
It seems it would only take a simple mistake to discharge a planeload of passengers into the wrong concourse. Presumably there are procedures in place to make such mistakes unlikely.
Is there any information on:
- Whether this has ever actually happened?
- What would happen to the passengers, in particular what would happen to domestic passengers who had been inadvertently mixed with international ones and who may not have travel documentation.
