AA status when booking, no status when traveling - seat selection, etc.
I was targeted and have singed for AA platinum status. I rarely fly AA and my status will expire in December. I plan to travel on AA in Feb 2020 and supposedly I could select complementary MCE seat when booking right now. However, will there be issues when I travel as non-elite in Feb? Will AA take these complimentary seats away as soon as my status expires?
