I've been through Heathrow Terminal 4 quite a few times recently. Every time it has taken less than 25 minutes to get from arrival at T4 (by the great Woking Railair bus) to past security.
Is this abnormal?
From the press, I should be stuck in huge queues and have my bags lost.
But that's BAA's fault, even though it appears to be BA's problem.Touch wood, so far BAA and BA have worked together very well.
