Flight delays at Heathrow but London airspace closure has little effect on US
FAA says it was not asked to hold any flights departing from the US to the UK, while Delta and United report few adverse effects
A computer glitch restricted airspace over London for more than an hour on Friday, but little adverse effect was reported on US airspace.
While some US-bound flights departing from Heathrow were delayed, airports in the US reported little impact from the air closure, which was sparked by a system failure at a national control center.
