I do mainly european travel in discounted seats, so never really get any miles, but I have had trip to paris business class with BMI and a Uk domestic flight with BMI and i am flying to BNE from the UK with SQ with a bonus in miles on the MAN to SIN so around 26k miles to come in from that, I also have 26k delta miles, and around 150k Priority club points to transfer to miles.
Mrs Dino, is also traveling to OZ so if there is any way to combine her miles into what I want below

What I want to work towards is Gold level with a ff program
I will be taking the flights In europe.
Not to worried about upgrades though it would be nice, just want the lounge access really as I find it far more relaxing, and have paid for it on occasion.

So who is the best to join

Thanks

Dino
