Dear flyertalkers,
After reading the forum for quite some time, the time has broken to post my first q.

I'm currently doing a trip in Thailand/Malaysia/Singapore. After quite some research and calculations and choosing the interconnecting flights in the right booking class, I will be qualifying for oneworld sapphire when returning home next week. I'm hooked up to Qatar Airways Privilege Club, and with some upcoming flights on QR I will benefit from the given Qcredits/upgrade credits.

When finished my flight back home, two days later I will be going to Honolulu with BA/AA. I noticed it takes quite some time for Qatar to process my status points and miles on other oneworld carriers, therefore I wonder if there is any way to prove I'm eligible for the sapphire benefits while doing the trip to HNL. Should I take my former boarding passes with an excel-sheet to prove I'm sapphire? Are the oneworld-lounges employees able to check my actual status, even if my account hasn't updated yet? I'm travelling with a friend, would be nice to let him benefit from these perks as my 'guest'.
