And it's not just AFKL.

Google can find no airline that would sell you two such disparate routes on a single ticket (which, when you think about it, is entirely logical; the "normal" traveller isn't going to be able to, or wish to, make their way the 7,000+ miles from Spain to Singapore by some other means (or on some other ticket) such that any airline could reasonably expect anyone to actually be interested in buying such an itinerary)
