When I saw the title of this thread I genuinely expected a different subject. In this country "Travellers" is a euphemism for gypsies and tinkers.
I detest business travel of this nature and I have to do quite a bit of it at the moment. Worst by far is that many domestic routes are dominated by British Airways, the world's worst airline.
I am a founder member of ABBA - Anyone But BA - and my idea of sheerest hell is a Monday morning (or Friday evening) spent at Heathrow Terminal Five - the shopping mall with a runway alongside.
