I am looking at this with a laughing and crying face at the same time. On one hand I will no longer be able to use my BMI mileage balance to redeem LH F for cash and miles, on the other hand availability of LH F awards should improve even more, so I can use my huge M&M balance to redeem these flights.
As long as I can continue to redeem cash and miles on TG F or NH F, it's ok with me. (of course this is only in my case as I have a healthy balance with M&M anyway)
