Service will be offered to customers in economy, business and first class alike from next month

Passengers on British Airways flights will be able to access fast wifi onboard at no cost after the airline’s parent company signed a deal with Elon Musk’s satellite company.

The carrier said the free “reliable and lightning-fast” wifi from Starlink would be available to customers flying in economy, business or first class from next month.

BA’s owner, International Airlines Group (IAG), said it had reached agreement with Starlink to provide internet connectivity on more than 500 aircraft across its carriers, which also include Aer Lingus, Iberia and Vueling.

BA said the rollout of the technology was part of a £7bn “transformation” and would provide lag-free internet access to passengers from boarding to landing, even when they are flying over oceans or remote regions. Passengers will be able to connect multiple devices and they will not need a special login.
