Flights from New York, Boston and Philadelphia have restarted after blizzards caused chaos after Christmas causing disruption estimated to cost airlines £64 million.

Airports and airlines are struggling to work through the bag log due to the cancellation of 7,000 flights after more than a foot of snow fell on the US north east coast. 

On Monday New York’s JFK, La Guardia and Newark Liberty International airports, Boston’s Logan and Philadelphia International reopened. In scenes reminiscent of those seen at Heathrow before Christmas travellers slept on terminal floors as flying schedules went into meltdown.

The airports were force to close on Monday after what was described as a “monster storm” swept across the eastern seaboard.
