I would like to think they would take I-94 or whatever at that point ... it's not really an airline issue, is it?
It's not an airline issue, but the
TSA is not
CBP either. It also makes sense to take the I94 at the gate when scanning the boarding card because otherwise the passenger will have "left" the country before they've actually got on the plane. What would happen, in that case, if their flight was then cancelled?
