Security delays
I think posters are missing the moot point here.
Paying for fast track is rewarding failure.
A failing security system generates additional revenue by forcing time restricted travellers to pay a hefty additional premium for a service they have already paid for.
The UK should adopt the policy of the Irish DoT where airports are fined if they fail to meet agreed performance standards.
Last year Dublin Airport was fined €700,000 for exceeding Queueing performance standards on 4 (four!) occasions, once by 8 seconds in excess of the 30 minute maximum!
Without some form of oversight by the authorities airports will continue to treat their customers with disdain.
