The depressing thing is the relentless predictability of it all. The interminable delays at security. The shuffling crowds in search of somewhere to sit as yet another flight is delayed. Worst, when you eventually escape you know the reprieve is only temporary. You will soon be flying back to broken travelators, long queues at immigration and mayhem in baggage reclaim. Welcome to Heathrow.

I could go on. I will. I have seen too much of Heathrow lately to feel anything but rage towards one of the world's busiest airports. Starved of investment, inefficient and understaffed, it is a veritable money machine for its owner BAA. For the rest of us it is a nightmare - the unacceptable face of monopoly capitalism.
