it is a useless offer unless someone needs to top-up on an award ticket they most certainly know exists. even for a domestic ticket, for instance BOM-DEL when 10,500 miles needed (8400 under the 20% off scheme), you get to buy 8400 miles for 7500 rs. i'd rather buy a ticket for 5.1k (Y) and get one extra tier point.
C'mon A2A, don't be a party pooper... More JPMiles! More Advantages!
