Brain hurts! Would folk please assist? I have a few questions, probably already asked by others. I am One Pass Platinum & matched to Mileage Plus Premier Exec. For SMD3 I will be doing the charter in PE. 2360 miles. Triple for PE, so 7080 EQM. For the optional European section on LH will probably be in Z. JFK FRA 3851 miles, FRA MUC 193 miles, MUC FRA 193 miles, FRA ORD 4343 miles. My calculations give me 12868 EQM. Will there be any difference posting to CO or UA? My thoughts are not, unless Platinum gives me more points / miles than Premier Exec. Second question, for flights SYD - USA, same question. My thoughts are if I post to UA then I will be more likely to get an upgrade, otherwise miles & points would be the same for the UA flight, probably in discount Y. I think all discount Y will post the same as each other. If I am on connecting flights within the US, do I get treated the same whichever metal is used, whichever site I book on & whichever programme I post to? If I book flights within the US separate to my international ticket how will it be treated? ie do I get treated the same whichever metal is used, whichever site I book on & whichever programme I post to? In the big combining of programmes at the end of the year will it look better for me if more of my travel posts to CO? What would you do? Thanks in advance for assistance.
