Well I would tend to disagree with the above statements regarding WW being desperate, selling 11 months in advance. BA also allow a very long advance booking period. IMHO their being smart, as most other LCC's won't release schedules and seats that far in advance, the punter might think thats a good fare and just book.
So I really do think it's a wise move for them but if they start chopping and changing schedules and timings, it may cause alot of headaches.
My 2 cents
