One thing everyone seems to be missing is the desperate use of "security" to drive up the cost/income.
Once they have got a suitable price hike, then we will see a drop in the need for security, starting with the stupid bits that don't really make life any safer in the skies. This will make BAA even more profitable.
The only question is whether BAA & the CAA are working in collusion to do this.
Its just an old trick rehashed.
