Here's my goal. I live in the BWI/IAD area. In 3 yrs = 2018, I'd like to travel to Asia. My question is about my return trip from Singapore. I dream of flying in luxury on Singapore Airlines. I hear they have 3 levels (First/Biz/and an upcoming 3rd level). Presently, I frequently fly on Southwest, Delta, United and AA/US Airways. What is the best strategy to obtain this dream without paying cash but with points? I'd love to fly in luxury going to Asia too but I think that would be a little ambitious and unattainable, perhaps? I am currently using the Hilton & IHG cards to harvest hotel points for the trip. Thank you.
