Here is a tricky one. Next week, I'm flying from FRA to LCY on a BMI marketed flight, operated by Lufthansa Express. My fare is a T fare, in economy. I use A3 for my *A points. I also care about BA points. With BMI in the midst of leaving *A, morphing into BA, what are my point options? I'm happy to earn points on either BA or A3...do I have a choice of either for this flight? Do T fares on BMI get meaningfully different credit amongst the programmes? Appreciate any thoughts.
