Group 0 boarding executed about as well as it could be given the circumstances of the "boarding pen" at LHR T3.

I didn't make there on time for what I presume was a group 0 call into the pen - but the separate groups 1-3 (well, 0-3) queue for the BP scan point allowed me to skip the long groups 4-9 queue.

Group 0 diligently called first when the jetbridge door was opened to commence the wacky races - allowing me to board first

An ex-BMI steed with moveable armrests and extra bulkhead legroom to boot, so I'm a happy camper. Well, apart from today's niggling delays.
