Hi all, I joined Ba blue in Aug 2017, and my tier points collection year ends in Dec 2018, I took a round trip premium economy from LHR to LAX which is operated by BA in Nov 2017, and some other one world carrier flight in 2018, I am bronze and have 1000 Tp currently, and I will take QR from HKG-DOH-AMS and BA AMS-LHR roundtrip next month, so when all these flight complete, I will have more than 1500Tp and 4 eligible BA flights, will I be upgraded to Silver or Gold membership? Thanks very much!
