I have a Chase Sapphire Reserve and live in Hong Kong. I spent quite a lot of money on travel and dining (USD 3000-3500 per month) so I'm getting very good value from the CSR.

I often travel in Asia with whatever airline is cheaper and to Europe through Air France, Swiss, Luftansa, Turkish Airlines, KLM etc. Hopefully I can find an airline program that could give me discounted economy comfort or premium seats. I was wondering if I should get another credit card or if there was an airline program that would allow me to maximize my points? Maybe I could combine something with a hotel program for example?
