Unsinkable terminal sinks at grand opening, badly.
Even before the new Terminal 5, British Airways flights out of Terminal 1 were notoriously late and troublesome. Most of that owes to its success in an odd way. I can't recall the exact frequency, but, with something like a BA flight landing every 90 seconds, a minor weather disruption will hit the airline disproportionately hard.
Anyway, the new Terminal 5 mess has taken about 4 days to be news over here. You'd think it would travel faster than that.
Virgin Atlantic opened its new Terminal 3 a few weeks back and I haven't heard a peep about that having been a problem.
