BBC article today says, in part:
Heathrow airport in London and Frankfurt airport both said on Wednesday morning that they were working to return operations to normal.
Heathrow's operator BAA said that both runways were now open.
It said it planned to run two-thirds of scheduled flights but warned: "Airlines are currently operating a significantly reduced schedule while they move diverted aircraft and crew back into position."
British Airways said that in line with a directive from BAA, it would operate only a third of its normal flight schedule at Heathrow until 0600 GMT on Thursday, Reuters reports.

"Officials at Frankfurt airport said early Wednesday that 70 flights were cancelled out of a planned daily total of about 1,300, compared with 500 cancellations on Tuesday.
Airport spokesman Thomas Uber said there was a backlog of about 3,500 passengers, including about 600 who spent the night on emergency cots."
and
"Eurostar said nine of its 52 trains would be cancelled on Wednesday, but the affected passengers would be reallocated seats on "one of the next available trains".
On Tuesday, thousands of people were queuing in freezing temperatures at London St Pancras station, waiting to be checked-in for a restricted service.
German rail operator Deutsche Bahn said it would change its timetable from Wednesday to 31 December and add extra trains to cope with a surge of demand due to air and road travel disruptions."
