My wife and me are both Skywards Silver, each with circa 90k miles. We both got emails to say we have around 35k miles expiring at the end of the month. We have upcoming J returns GLA-MEL in December so I went into MAB and it says upgrades available but only on DXB-MEL and 140k each! Upgrade not feasible even using all the miles before the end of the month.

The next thought was spend 35k miles in Emirates High Street before losing them. We've both identified items we could purchase.

Before doing this I wanted to check that we will be left with 55k miles after the end of the month? I.e. we won't go down to 55k after purchase and then have 35k taken off on 31st? In essence are we spending just the expiring miles and not dipping into the balance remaining?

Thanks in advance for any advice.
