Looks like we will be moving to Singapore. I am wondering if Singapore Airlines are so good that it would be worth working my way up their Kris Flyer scheme or should I stay faithful to BA? Obviously, I know what I am getting with BA (usually travel Club though sometimes PE with family). I will be flying LHR-SIN at least x3 p.a. plus a couple of trips to North America.

Is Singapore Airlines worth the switch?

Thanks!
