Betty girl,
Your thanks are welcome indeed. Doing crew support was important for two reasons: (1) as a deterrent to anyone who wanted to create trouble (2) to provide reassurance to crew travelling to or from work.
Volunteers were stationed at the crew car park, crew buses, Arora International, Cranebank, landside departures and arrivals at T5, baggage store at T5, airside arrivals at T5, CRC. There were people doing crew support at LGW as well.
However, the shifts were mostly boring, but volunteers did the shifts as they felt that this was a job worth doing. So, any thanks make the shifts feel that bit easier.
