I plan on signing up for a oneworld program.

The majority of my awards would be from NA>Europe RT. Are the programs all mileage based or are some zone based? I was looking at AAdvantage but it was a bit confusing as they had a bunch of different charts. That program looked appealing to me because of the AASaver awards which are half price of a normal award. I saw NA>Europe in F for 62,000 points on one of the charts?? Crazy cheap.

My main concern is with redemption rather than accrual. So whichever program is best for NA>EU redemptions would be best for me.

Anyway any input would be appreciated.
