British Airways is among the airlines cancelling flights to the USA because of 5G safety concerns.
The action is in response to fears that the activation of the C-band strand of the mobile phone service near US airports on Wednesday could disrupt planes’ navigation systems, with Boeing 777 jets thought to be particularly at risk.
The introduction of the technology has been halted in some parts of the US but is going ahead elsewhere. The UK’s Civil Aviation Authority (CAA) said it has “issued safety advice” to airlines.
