Similar picture with friends in the North. Some are looking at the Edinburgh to zeebrugge ferry, and then via rail around europe/contintental flights, and other looking at the Newcastle-Ams for week long business trips. The fact that absolutely everything including car key/phone/documents is 'put at risk' in the hold will make business flying pointless. Add in the extremely long queues etc... and we can be sure it will knock aviation hard in the UK.
I fully agree with tight security, but when the whole focus of BAA airport management is on 'retail opportunities', it is hardly going to get better in the short term.
Out of choice, I probably will try to avoid any flying in the short term, just because of the hassle, queues, and hand baggage restrictions.
On a more important point, can someone confirm if it is still the case that someone can work airside in an airport/airline for six months before security checks are complete?
