Hi. I just got matched to United MileagePlus Premier Platinum. I am a newbie with all of this. I have a flight 2/7 – 2/21 to BKK from MCO. How do I request and confirm free upgrades to business/first class? I have a connection at NRT on ANA to BKK. How do I request my upgrade on the ANA Alliance flight? How do I know which Alliance lounge I can use at NRT? What tips do you have for me? Thanks for your help!
