IMO, other than from a marketing standpoint vis a vis codesharing flights, I dont see any financial benefit from any "alliance" such as one world or star alliance.
You are seeing the signs of financial pressure as mighty LH has cut the purse strings on the poor stepchild - Austrian Airlines. Austrian has to stand on their own feet or they will be dumped. The interesting thing is Emirates and Etihad are just standing back and will put money into these carriers such as Austrian and Air Berlin to gain a stronger foothold.

If BA cannot, what about IAG or OneWorld as a whole?
