I went through security at Stansted this summer without waiting - I
was past security within five minutes of having got off the coach.

I did and waited over 45 minutes, like usual. Luton can be as bad but
at least if you're in a hurry there is the facility to pay for fast-track.

Er, as there is at Stansted. (£5)

That talks about booking it - is it also available on the day (for
example if your train was late).
