I have an up comming trip on Virgin - Qatar to India comming up. I am not sure which program i would like to put in my miles.

current status:

US DM - 20K
United MP - 12K (12.5K - EQM)
Delta - 15K
Continental - 1K


My itenerary is IAD -Virgin- LHR - Doha - HYD (rest is Qatar). (& return)
IAD - LHR = 3.7K,
LHR - DOH = 3.2K
HYD/BOM - DOH = 1.6K

Virigin -> seems to allow transfers to Continental (EQMs) / Delta / US
Qatar -> US (EQM) / United

My interest is either to get a free coach round trip to India / Canada. I use United chase, Amex Delta & Spg cards.

I was thinking of putting them in Continental & US or all of them in US. I fly out of Bos ... mostly to DC / PHL. Thanks for your help.
