I have the Cathay AMEX Elite & Citi Premiermiles, and need to find the quickest way to earn 60,000 AM in the next few months for a oneworld multi-carrier award. Are there any decent sign up bonuses apart from the SCB Asia Miles Mastercard? I am seeing a 40,000 bonus there - which really I'd get 15k out of since all my spend will be overseas, and anything over the first 7500HKD is only 1AM every 4HKD which is the same as the AMEX and Citi card anyway. I pondered too long over purchasing miles during Citi's promo, so missed out on that. Any help would be much appreciated.
