Okay I'm sorry if this is a stupid question, I did a quick Google but couldn't find the answer.
So I'm flying to the UK in July with Cathay pacific. As they are part of the one world group, do I earn FF points on both Asia Miles and qantas or I need to choose who I want to earn points with? I currently don't have either membership numbers against my booking so want to find out the best way before I add anything. Thanks.
You need to choose, you don't get both.
Really depends who's program you would benefit most from
