I am in a similar kettle of fish. Between 25 July and 20 September I have 8 Business class flights (OK several are with AA) on 2 different PNRs. All within EU and also USA and Canada. I have been getting notices from BA of schedule changes and of flights from LHR being done by Finnair instead of by BA. Uncertaiiiiiiiiiiiinty as 25 July creeps nearer.
It does not bode well as I need all 450 TPs to maintain Silver. Starting to wonder if my *A status will be better to maintain...
