Ah was going to mention what Alfursan was but think you made an edit. I'm only signing up with them as I have two buisness class flights with them. And will possibly book another for next year.

Sorry yes maybe my misunderstanding but I am sure one of the alliances you mentioned I had to sign up also. I understand I need to collect points or miles with each FFP, but I thought the point of the alliances was that you could combine/earn points with various airlines within each alliance to create airmiles. Maybe I misunderstood that too..But I guess it makes more sense to fly with just one airline, as the replies suggest to earn more miles quickly.

Getting my head around mike runs and airmile cards so i'm just at the beginning of understanding all of this. I understand you suggest AF/KLM because I'm UK based appreciate that.

Sorry Alfursan I think have other benefits if you sign up to their membership I know this is nothing to do with a FFP or alliance. I hopefully will be using the lounge as part of my flight so not looked into that yet, just saw there was something else to sign up for

Thanks so much
