Barabbbas, first thing, LM is truly fickle. Often when you select a specific airline it gives that dreaded message that "this route is unavailable with that airline", but even so, if you allow it to use "other" airlines, it suddenly lets you book via the same airline you tried in the first instance... Second thing, many LM award fares are only available either almost a year out, or in the next few weeks. I have found recently for my routes that Turkish is in the middle. And thirdly, and perhaps useful, is that some airlines will show availabilty as a multi-segment A-B-C when a simple search of A-C brings on that dreaded message. But if you go down this latter path you pay for individual segments, which is expensive.
