Hi there - each of my 3 kids (minors) have their own Mileage Plus account with around 50k miles each. I am wondering how I book award travel for them when the whole family is going together? I don’t want it set up as an unaccompanied minor ticket nor do I want to pay the fees to transfer their miles to my account. I know you can “link” reservations after the fact but that’s not the same as combining them. Any ideas ?
