I had been looking at Qatar's
Book with Confidence Policy on the idea of booking a ticket for travel before Dec 31 and being able to change the destination & dates without a paying the fare difference. Anyway, I noticed that IAD<>BEY is super cheap, and IAD<>GOI is almost just as cheap (and covers more of asia with the 5,000mi change radius if that's what you're interested in)
Pretty wide availability this summer through next year
