LHR Check in time, security, etc
Evening all,
Haven't done LHR for a while.
Daughter flying BA to Berlin from LHR - 0715 in the morning soon.
Taxi driver (me) meant to be working late night before driving her there next morning.
What's the timing for LHR check-in, security, etc. BA state 2 hours before flight time?
In other words Auxtank pleads to know what time is reasonable time (leaving a respectable margin) to be walking into T5 if flight is at 0715.
With thanks.
