Have 1 Million AMEX points and want to fly family (total 4) round trip

Hey guys! I've been accumulating Amex points for a while now and I have just a little over 1 million.

I want to book business class for my whole family, round-trip from either Newark or JFK to Bangalore, India, in August.

I was wondering what is the best way to do this would be.

Doing it through the Amex travel portal seems totally not worth it because it's asking for a lot of points.

What are some good transfer partners for this route that have a good business class for relatively fewer points?
