as to the OP:

where is your citizenship?

if you're American, for instance, authorized users on your card back in the US.

when i am in asia, i have my sister doing MS for me back in the US when she's able. mom's a bit too old, so she's done except when she needs to generate a ticket to visit my sister, she jumps back in to top off a miles account. since i provide support for both, i pay their rent and other bills via bluebird accounts i set up in their names. BB raising the account limits has helped, but i wish i could load more than 5k/month. the reality is, in good health or not, hard to get people to play the game for you. we deal with the hassle of running to stores buying cards and liquidating them. after a couple times, others are like, 'hell no!' lol
