Have to agree with Faire DÍncome ...I pass through LHR T1 several times a week and have to say it is appalling. The poor old BAA staff do their best , but are dealing with a lack of investment in infrastructure (unless you count the duty-free shops) Queues everywhere, long walks to gates through badly lit and unfinished corridors, with wires and cables hanging out of ceilings. Doors slammed in pax faces, as "sorry mate, incoming pax coming through here...not allowed to mix the two" In short , it seems badly organised. Walking through Mexico airport the other day, I marvelled to the other bloke " how come Mexico can afford a decent airport and we are still in the dark ages?"
