I'm one of those infrequent flyers that collects miles almost exclusively from credit card spend and buying miles.

At the moment, I have 500k plus Avios, collected mainly through Amex Platinum spend and bonuses (inc referral bonuses to and by hubby and the 100% Amex transfer bonus in the summer which was too good to resist). Plus about 150k DC miles, almost solely from MBNA Mastercard spend, plus 500k+ US Airways miles, mostly bought or from the brilliant Grand Slam promo.

I have an Amex Platinum, so no concerns about lounge access and as I pay to fly infrequently, status is not important to me. I also have a SPG Amex and put everything I can on that as that is a route to more US DM, holding them until SPG have transfer bonuses.

My main priority is being able to fly in premium cabins between London and Sydney and, to a lesser extent, other longhaul flights. I'm content with using LCCs in Europe having tried BA Club Europe last year and found it a complete waste of money.

Availability of award flights to Australia on BA is negligible and there are of course fuel surcharges, so preference so far has been using US miles on *A partners; I was saving to do the same using DC miles eventually but there are no plans for a trip until 2013 now so too late for DC. But even that seems to be getting harder with LH now blocking its premium cabins until too close to departure for me.

Basically I accrue BA miles because it is so easy to do in the UK, although I don't actually have much use for them (and object to the fees). From what little I know about FF programmes, *A seems to be much more my natural home.

Really what I would like to know is if I should be doing anything different/looking at different FF schemes etc. I presume I will need to find another non-Amex card once the BMI one gets scrapped, but other than that do you have any suggestions being in mind my objectives?
