VS "offer" sounds like panic. Why would LH want to tie-up with Sir Dickie Jumper? They've got plenty of slots for their own Longhaul op out of LHR (especially when SAS is gobbled up) and can now have directional hub and spoke traffic i.e. going east then you transfer at MUC/FRA...going west then you go through LHR.
Times have just got interesting for the jumper and the leprechaun
