I think a bigger question is also what class of service as well? If Y, then OZ might be a better bet; if F/C, then BD/M&M are probably better bets and they offer the best accrrual for premium cabin miles by far, in addition, M&M has agreements with SQ and is the only other program besides SQ's KF that can redeem for 77W F and C on 345's, 77W's, and 388's.
