In my review of Singapore Airline's First Class Suites recently, I promised I would tell you all how I earned enough airmiles to buy a First Class Suites ticket from Sydney to New York City (40 hours total flying time). So here we go! Now, you can definitely earn those miles purely from credit card sign-up bonuses (key ones are the SPG Amex and AMEX Gold Card), however I did earn a lot of my miles through my normal flying. I earned 120,000 miles within one year, and then a further 65,000 in the second year, totaling 185,000 Singapore Airlines Krisflyer miles. This post is mainly aimed at residents in the UK and Australia.
