We will be travelling to India in December and want to use miles for business class tickets. There will be 3 adults travelling. Is 280,000 miles per ticket reasonable for this time of year? Is February better for lower miles? What is best route from Seattle to Mumbai and back from Delhi to Seattle? I would like lie flat seats. Korean is a skytrax 4 star airline and I would like to fly to Mumbai there and AF back. Any other suggestions?
