Swiss are using their own a/c on all Geneva flights in the Summer so that frees up a bmi a/c for the Basle.
GVA was operated on an A320, BSL will be operated on an A319. This A320 will be used for LH flying from BHX/MAN.
As I see it the LHR BSL and MAN BSL requires 2 aircraft, one from the LHR GVA and the other.......??????
The BSL flying programme only requires 1 A319 as the MAN flights will be operated as a W-pattern with the LHR a/c.
