I'm sure that J* Asia will turn a profit one day.
I think it was last year rather than "one day", both second half of last year and first half of this year were profitable. Tiger is fairly profitable overall and it certainly isn't coming from Australia so Singapore must be doing pretty well. And if Tiger can make very good profits in Singapore it doesn't seem that difficult to believe that J* Asia is profitable.
As for aircraft acceptance in Toulouse, how many people does it involve and how much of the work relates to J*? (This isn't a rhetorical question, I am interested in the numbers).
