Axis gives similar 5:4 transfer to both Marriott and airline partners. While Amex has 1:1 transfer to Marriott but 1:0.5 for airline partners. Considering this to maximise the value of reward points does it make sense to transfer Amex only to Marriott and use Axis Edge for airline transfers? Any reason one should use Amex points to transfer to airline (assuming you also have Axis edge points)? Discussing normal transfers here and not with bonus offers.
