im not sure if this has been discussed here...i searched around, looked at ual.com, couldnt find specifics.
is it possible to use my miles to upgrade a ticket for someone else? my sister is visiting me in about a month, and on her way home she is flying alone for the first time. i want to upgrade her to F so that she can be taken care of and relax, and end her trip in style and comfort. obviously, since she is returning home, i will not be on the flight with her. is this allowable?
