Saw this on an ad:
Join KrisFlyer, the frequent flyer programme of Singapore Airlines, and earn KrisFlyer miles for flights, seat upgrades and more.
What’s more, sign up using JOINKF2017 by 14 April 2017 and you’ll receive 500 miles instantly!
I was looking forward to using SQ miles for UA flights, but since their award space on premium transcons to LAX and flights to HNL has gone to crap, well...
