greetings all...i have a question:

this is my first year as a silver, and i've already hit the miles qualifier to be silver again next year (haven't hit PQD and probably won't, but i have a large purchase upcoming that i'm putting on my united card to hit the waiver). in mid-november i'll have a flight where i'm flying with both fiancee and my mom...is there any way (via call-in or otherwise) to get in E+ for both of them at check in? or am i stuck with only getting E+ for myself plus one of them?
