I was all set for the MR, then logged into ba.com and realised there had 40 more tier points that I thought...so rather than needing 60TPs I now only need 20TPs. I currently have 1360 TPs, with 3 further flights LHR-MAN-LHR booked for the next 3 weeks, so that takes me up to 1480.

I thought there may be a cheaper option that the LHR-CDG-LHR MR, but at £202 it seems like the best value.
