Hi everyone, I am new here and a TOTAL newbie in the world of frequent flyer programs. I am super excited because I recently got a new job, in Amsterdam, which will allow me to visit clients all other the world (from Chile to the Philipines), but I have no idea how to get a maximum out of any frequent flyer program.
Tomorrow I'll be flying to my first client in Norway with SAS and I am wondering which frequent flyer program from Star Alliance should I join?
PS: I am already a Flying Blue member for my KLM flights.
(1) AMS
(2) mostly Y
(3) Around 25-30K
(4) nope
(5) free lounge access, easy parking
(6) mix
(7) KLM, Brussels Airlines, SAS, Lufthansa
(8) I'll gather most of my points for work, and I don't have the choice of Airlines
Please help me

*sad face*
