British Airways has said it is ‘disappointed’ at having to cancel some services to the US over concerns that 5G services being rolled out near airports could interfere with aircraft radar technology, with Boeing 777s believed to be particularly at risk.

The airline cancelled some flights from Heathrow to Boston, Chicago, Los Angeles, New York, and San Francisco on Wednesday.

A BA spokesman said: “Safety is always our priority and although we had to cancel a handful of services, we’ve done everything we can to minimise inconvenience for our customers.

“We’ve changed the aircraft operating some of our flights and rebooked those on cancelled services onto alternatives.  

“We’re disappointed that, like other airlines, some of our customers’ travel plans have been disrupted.”

Other airlines, including Emirates, Lufthansa and Air India have also cancelled flights.

Japan Airlines and ANA said they would resume Boeing 77 services on Thursday, after being assured there was no safety issue now the US networks have agreed to delay rollout of 5G towers that are close to airports.
