Sorry if this has been asked before. Currently, I'm a BD *G and decided to make a run for MP P and likely PE this year. I booked my first trip that will credit to my UA/CO acct. Its booked on CO metal. On the CO site it asked if I wanted to buy up miles, and it is making me buy the elite maximizer as well, its also asking me to use my CO One pass #. Just a few of questions: 1. If I purchase the elite maximizer, and buy the addtl miles, will that elite credit move over to my UA MP acct when I do a miles transfer? 2. Does the elite maximizer purchase also cover mile buy ups on united metal flights, or is there's a completely different platform for buying up EQM eligible miles? 3. Its offering me a first class buy up, if I elect it, does it become an "F" or "A" boarding pass for purposes of EQM multiplier or is it considered and upgrade and I only get my original Y miles? thanks!
