I reckon that anybody going airside must go through the same process as the aircrew, not the other way around.
Sciolistes has it in one here. We all know, anecdotally, that the rules and procedures are not applied uniformly.
Until there is a will at political level for change, then nothing will change.
Aircrew only have themselves to blame for this situation arising. We
should be very concerned about these disparities but until all crew members are on a united front little will change.
A day of action (or inaction) would force the issue. On a parallel if you told the train drivers and railway signallers that they couldnt take yogurts to work Bob Crowe at the RMT would have called an immediate strike, the network would have ground to a halt and it would have all been sorted within 24 hours!
Finally, the western world needs to ask itself the question as to what we are doing (and have done!) to cause "terrorists" to want to put bombs etc on aircraft?
