Weynand,

I usually find it difficult to book award tickets during the school breaks in Europe (July/August) but fairly easy during other times, especially upfront.

Also, people are afraid that there won't be any Swissair / Crossair successor after March 31st (or at least none flying their route) so there shouldn't be too many bookings on SR/LX.

On the other hand I could imagine many people tapping Qualiflyer's contingent of free seats on partners (CX, QF) because of that fear.

So I'd suggest you either book early on a partner or wait until SR/LX has published their summer schedule and then book there.
