Seems that IATA thinks that UK airport screening only benefits the airport operators and doesn't improve security.
I guess this probably needs to end up tacked on a previous security thread, but for a few hours it's news of a sort.
"A particular focus will be the UK, where unique screening policies inconvenience passengers with no improvement in security.
"The only beneficiary is the airport operator BAA that continues to deliver embarrassingly low service levels by failing to invest in appropriate equipment and staff to meet demand. This must stop."
