Need to add segments to DTL-AMS-BOM-AMS-DTL to maximize BIS miles. I am going to BOM for 3 weeks on some personal work from Aug 3rd week for 3 weeks. Currently I am getting DTL-AMS-BOM-AMS-DTL for $1450. Can the veterans suggest adding more segments to maximize BIS miles for little more or no cost than $1450? Currently DTL-AMS-BOM-AMS-DTL yields 16,000 miles.
