AMEX points for AVIOS
I have accumulated a nice chunk of AMEX Membership Reward points (about 700k) and there is currently an offer to transfer for Avios at a 40% increased bonus. I live in Texas and would like to travel from there to Europe occasionally in F. Normally I fly United, and have about 400k points with them, but AMEX does not partner with them. Given this, does it make sense to transfer for Avios now while the bonus is in effect?
