The GB S08 MAN routes are on sale now on BA website, and will remain so until the aquisition of GB is complete at the end of Jan ?
Therefore, I take it that if seats are on sale tomorrow on EZYs website then either A) GB is theirs early and it is the GB routes or B) Its not GB routes yet, but a selection of other new routes. You decide...or better still wait till morning
Happy New Year
