Preusmably everyone will have to show their face at exit checks, just like entrance checks?
I wonder how this will be introduced at airports. Surely they will have to either deploy UKBF staff to every international gate (rather than the spot checks they currently do) or rebuild departure lounges to include separate international and domestic areas?
Im not sure which is better. Option 1 would need a hell of a lot more UKBF staff but could be implemented very quickly and option 2 would cause huge disruption at airports as they work to rebuild their post-security areas, much like schengen and non schengen areas in Europe today, but they would have a single point of checks with limited extra staff numbers. Option 1 would mean faster journeys through the terminal until the gate, option 2 would mean that once security and immigration are done there is then no further delay.
