I received the double miles promo from Cathay (I believe it's targeted) good Feb 7-Apr 30. F, A (First Class), J, C, D, I (Business Class), Y, B, H, K, L, M and V (Economy Class) are eligible to earn Double Asia Miles. It seems like a nice promo and they have some decent rates during the dates. I'm not sure why I was targeted. I haven't flown them since late Oct. and I didn't make status with them last year so not sure if one of those is the reason. Tempting offer.
