1. With AF you will have 260k miles. You could get 2 award tickets in PE for BLR-MIA & JFK-BLR in that. The rest you will have to pay cash for. Or you could get 4 award tickets in PE for BLR-MIA (or on the return) and buy the remaining as one ways with cash. You could potentially use the UK miles to buy UA awards on the MIA-EWR leg but that would not be good value.

2. With UA you have 210k miles. You could get 2 award tickets in Y for BLR-MIA, MIA-EWR, NYC-BLR. And buy the rest with cash. This should cost you 176k miles or so. So you could use the balance to buy 1-2 MIA-EWR award tickets in Y if possible.

You will have to check which route economics and other factors work best for you. Depending on how you look at your miles - just to burn, or to extract X value etc. would be a personal choice. But these are the only options I could think of.
