British Airways operates a fleet of 59 Boeing 777s, of which 16 are Boeing 777-300ERs. These are some of the workhorses of the fleet, and they are particularly put to work servicing BA's US routes.
Although replacements are on the way, the legacy carrier operates the bulk of the remaining aging aircraft type.
Thai Airways is set to announce the end of its rehabilitation plan, new products, and Boeing 787-10 deliveries.
