I am in a similar position - yesterday I was unable to work from 1445 until 2230 because everything I needed had to be put in my hold luggage.... Normally I would have managed 5 hours paid work in that time.
Next time I'll probably drive to Lake Constance and back, since the company pays for travel.
54 flights so far this year - thnigs must change soon or there simply won't be any UK airports..... I wonder what the total loss of business in the airside UK duty free shops has been over the last few days?
