Had something strange happen today. Wife & I are both 1K. We both booked Prem+ A fare tix on Intl Polaris flight in 2 days, with Plus Points applied many moons ago. When UG list became visible yesterday, I was #6, she was #7. Today I have moved up 2 spots to #4. She is still #7. No other changes to first 10 on list. Her 1K status comes from my MM benefit, and I probably have $25K spend on my cobranded CC, but why did this change today?
