U.K. Airport Traffic Chaos Takes New Turn on Heathrow Fog

Passengers flying out of London endured a fourth day of disruption in less than a week as fog caused delays and cancellations at Heathrow airport.

As least 200 flights were scrapped today at Europe’s busiest hub, spokeswoman Lizzie Humphreys said, while a larger separation was required between landings to ensure safety. Gatwick, south of the capital, faced minor delays and was accepting flights diverted from other airports.

Further north, London Stansted returned to normal operations after closing to incoming aircraft yesterday morning, when a Gulfstream G550 business jet damaged the airport’s instrument landing system in thick fog. Ryanair Holdings Plc was forced to divert at least 15 flights.

The cancellations at Heathrow extend a run of disruption that began at the weekend, when thousands of passengers were delayed at airports across Britain after National Air Traffic Services Ltd.’s Swanwick control center suffered a technical failure while switching from nighttime to daytime operations.
