I am *G as a UA1K and AA PLT and have had the same dilemna for years...and still cannot decide. If it wasn't for BA being so restrictive and treating customer with a Continental european address in a discriminating manner, I mean by that that they are even more restricive as far as the type of fare eligible for miles, I might give more business to OW.

Talking about quality of service of the partners: SQ has a fantastic product in all classes of service. LH F-class is very good and as said earlier, the new J-class looks very promissing. AC, SK and BD have very acceptable standarts as well...and TG, despite the quality of the seats and IFE, more than compensates with the level of service provided and the quality of the meals. RG is alright if you fly on their new 777s, not worse than UA anyway. Finally NH is just one of the best airline in the world today and their new F-class and J-class seats are top of the line.
