Before people start cheering, will non-transferring pax still be allowed to walk from the aircraft straight out the front door of the terminal without any interference from Border Security.
I wonder what percentage of BA passengers on the London routes don't transfer. I'd hazard a guess that the vast majority of those travel on EI or FR.
