How does the year work?
Say you achieve the 100SP in January does that mean you have Qantas gold February 2025 to January 2026 (achieve 100SP in February Qantas Gold March 2025 to February 2026) ?
If so then the best is to achieve 100SP in April 2025 so you effectively get QC January 2025 to April 2025; Gold May 2025 to April 2026 ?
