Here is another one for you....my plan is to arrive from a domestic flight in T1 and then take a BA international flight out of T1 (LAX). Say I am at the gate and I get bumped off - how easy would it be to get back from T1 international to T1 domestic arrivals and from there back through to T3 for the Virgin flight??
I don't understand, why would you want to go via T1 Domestic? T1 International to T3 goes through the FCC, but you would have to clear connections security.
