Sygyzy: no harm, no foul. It's just that given the time variability with which a flight actually does close its door, and given the very long lines at landside check-in desks and with security, I would very much prefer to have the option of sorting out my issues (such as they may evolve) from the airside of the airport and not out by the street. In general, I would think that this would give me more options.
In any event, thanks for the heads-up. I shall not be dawdling landside when I next visit LHR.
