I am working part time for a large company in BSL. Yesterday there was a meeting between SWISS officials and my company because the company is unhappy with the current route network out of BSL.
However, SWISS confirmed that BA will take over the flights from Heathrow to Basle and Geneva and probably also between Manchester and Basle. SWISS gives the LHR slots to BA and receives 50 Mio. CHF. This is subject to the approval by the government because several airlines (EasyJet for example) do not agree with the slot deal. So I guess we will see these changes effective next winter schedule.
SWISS will only serve Heathrow out of Zurich then!
BA (and BOAC) has served Basle for more than 50 years and was one of the first airlines flying to Basle after the 2nd world war. They have dropped the route in the late 90s due to the Crossair competition (which had 6 daily flights to London).
Welcome back mates. We will welcome you with open arms.
