Airports in the capital are resuming normal flight schedules after dense fog forced two days of substantial delays.

The news comes after the cancellation of more than 120 flight departures as well as 104 arrivals at busy Heathrow airport since Sunday evening. However, the disruptions are beginning to flee; the fog has lifted but travellers are still advised to check with airlines and tour operators before heading to the airport.

Heathrow handles a whopping 1,300 fights every day; a spokesman for the facility told reporters that all flight restrictions had been lifted and that the fog had cleared.

Disruptions also had spread to other London airports; Monday saw 13 arrivals and 18 departures cancelled at London City. A spokeswoman for the terminal said early on Tuesday that there were no current delays but that travellers should check with airlines nonetheless.

Numerous passengers were stranded at the airports amid the passing fog. Some were provided with hotel accommodation and Heathrow officials said that some passengers with bookings for regional destinations were transported by coach.

The ordeal also caused backups at UK Border Agency checkpoints. Some travellers complained of ‘inefficient’ management amid queues lasting in excess of one hour. A spokesman for the Border Agency said they had quickly brought on extra staff and that officers had worked as quickly as they could to handle the problem.
