LHR - BIO on 19 May
Closed gate, had two old school lanes for ticket and passport checks. All bundled into the same waiting room.
Babies and wheelchairs called first.
Then Group 1. Didn't see what happened after that
BIO - LHR on 23 May
No lanes but a long queue of people to one side with another shorter queue in front of the entrance to the jetty. We must have arrived just after the announcement had been made and simply followed a couple we saw in the lounge. So, can't report at all on any attempt to follow the new system.
