Whilst on the subject of LHR-TLL-LHR, has anyone challenged BA for showing all the AY codeshare flights to TLL via HEL as sold out in J for every flight when trying to book on ba.com 355 days in advance? They seem happy to sell Y on AY metal but it's not very "One Worldy" of them. Has anyone tested booking Y in the hope of a POAG at a decent price?
