I am BA EC Gold, which earned me Emerald Tier status with Oneworld. I'm flying to from London to Phuket on Qatar on March 23 - while I am still officially BAGold/Oneworld Emerald. However, my status drops from Gold to Silver on March 31 (from Emerald to Sapphire). I fly back on April 3.

My question is, will I lose my ability to access the first class lounge at Doha on the way back? And does anyone know whether the Qatar lounge agent scanning my boarding pass will actually see that I lost that status on his/her computer? Thank you.
