That reminds me.. What's the general consensus on what's the better deal?
Amex&RBC-> Avios (1.5x promo on RBC, not sure if there's Amex promos?)
Amex->Aero (no more promos

) and RBC->AA (only 1.25x promos)
? I'm torn between Avios and AA... I'll be using it mostly for flights from YVR-ZRH so I can fly AA all the way by connecting through JFK (or CX for the awesome YVR-JFK plane)
(I live in YVR, my family in ZRH and I do the roundtrip once a year)
BA has worse award pricing than AA but better conversion value... Has anyone done the math on this or can tell me about some other factor I'm forgetting?
