I'm going to travel with my wife.
I have some miles and my wife also (but less)
Can we book ticket for us using miles?
But: some miles (e.g. 75% of the total miles required) would be from my account, and some miles (e.g. 25% of total miles required) would be from my wife's account?
(or the only option is to transfer miles between account - which is very expensive way to use them....)
