Quoted from amputee's posting

"If the transactions were to Europe, I'd just jump on the next available bottom-price easyJet - despite their cocrete seats"

;-) Quick point on this.

You have to declare at customs if you are entering a European Country with more
than X amount of cash. I think the current value is 10,000 euros / £s. Not sure if you have
to mention anything when you leave the UK but you are asking for hassle if you have large
sums of money on your person or in your bag(s) as you go through security control.
