Some airports with "international" terminals - like ATL and LAX- also have international flights leaving out of the regular terminals.
So, no, it's not as easy as just putting up some CBP booths on the other side of TSA to process foreigners heading out of the US. Since there is currently no constitutional requirement for US citizens to have permission to leave the country, there will never be exit controls on US citizens. So, there's zero chance that a system of international-only airport terminals will be built just to process foreign visitors on their exiting flights.
What a completely arrogant, inaccurate comment. What does having exit controls for international flights have to do with "permission" being required for US citizens? That's right, absolutely nothing. Have you ever been to an airport in most other countries outside the other US, whose citizens also don't need "permission" to leave their country? Guess what - many of them have exit controls.
In the US the issue is a logistical one, not a constitutional one. But it is not inconceivable that outbound international flights could be moved to a specific area, or set of areas within an airport, just as inbound ones are today. The simplest way of achieving this would be to nominate a set of gates at the end of a concourse as outbound international gates and put a series of CBP desks there. It could even be a temporary setup that was only activated for a number of hours each day.
It really is only a matter of time before a system like this is put in place.
