'Dozens of planes' scattered around the world as Heathrow resumes operations - travel expertpublished at 07:32 Greenwich Mean Time 22 Marchpublished at 07:32 22 March

A little earlier our colleagues at Radio 5 Live heard from travel journalist Simon Calder.
He says that British Airways are the worst-affected airline from yesterday's shutdown and have "dozens of planes" scattered around the world "from Reykjavik in Iceland all the way to Bavaria".
He explains that overnight British Airways cancelled half a dozen long-haul departures, as well as the corresponding in-bound flights. That's affected routes to destinations including Chicago, Boston and Dubai.
There has also been a number of short haul cancellations - but not as many as British Airways was warning might happen last night.
Globally, he says, around 10,000 passengers are affected today on top of yesterday's total. For those experiencing delays, Calder says the rules are "clear" - passengers have to be rebooked "as soon as possible".
The travel expert adds: "it’s costing the airlines £100m just in lost revenue - but on top of that you have the emotional cost which in incalculable".
