These belt wielding terrorists must also have been in action in Florida too. I was on a flight from MAN-MCO at the end of January - no belt problems but had to taste baby food in front of them. Two weeks later on the way back I had to remove my belt for scanning but baby food was fine.
I think they are rotating the threat to keep those wily terrorists on their toes. Funny though how BHX are making profit from the measures though although not as scandalous as 'offsetting' your carbon emissions which, yes, you've guessed it, costs money too!
Before we landed we were given a sob story about how the planet is dying but if you dig deep into your wallets (what a surprise) you can save it.
Maybe the next step is that you pay for extra security!
