I would also expect reaction from Unions and travellers groups etc to be hostile, but really, you can use other airports if you don't like it. However, what has caught my eye is the response from the Easyjet spokesman:
Andrew McConnell, spokesman for EasyJet, the largest carrier at Luton,
"Service enhancements should not be at the expense of passengers who
have already paid for a reasonable level of security.
"The customer has already paid a fee to use the airport as part of the fare. This seems to us like double-charging. How many more staff have they taken on to introduce this?"
"It is part of a worrying trend which we are noticing at a number
of airports across the UK. If they are not charging for fast-track security,
they are demanding money for plastic bags in the case of Manchester or
additional levies for 'development'."
