British Airways will fly from London Heathrow to Guernsey. It last did so 45 years ago, in 1980. The airport pair has seen various carriers over the years, including Air UK and Flybe, which operated for 12 months until March 2020. Elsewhere, BA CityFlyer also flew from London Gatwick to Guernsey until 2003. Of course, Aurigny already serves Guernsey to Gatwick and London City, although the latter route is at risk from BA’s entry.
