Just be mindful that if your CX sectors are CX-coded rather than BA codeshare, you'll get a disappointing drip-feed of Avios. QF is marginally better but still rather tightfisted with Avios if in Y.

If your TA are doing the bookings, make sure all sectors are BA codeshares to allow for UUA or at least split the booking if you're feeling brave about unprotected connections.
