You EARN miles with credit cards and you SPEND them on flights. So that means you focus on credit cards that transfer to a number of different airline programmes, which gives you maximum flexibility to find award space.
There's no point earning miles based on what an award chart looks like today. Tomorrow it could be devalued...
