What's the most efficient way to collect airmiles?

[puffling]

Should I get a credit card that gets me airmiles? If so, what one?

I collect airmiles with my electric and gas, Scottish Southern Electric, or whatever it's called now. I've been collecting with them for years.

I recently got a Lloyds TSB credit card which I can collect airmiles with, it's been so good that I've collected loads in only a few months. It was brilliant at Christmas as I was able to order gifts on the airmiles website using my airmiles card which meant I got double the miles!

I have a clubcard but don't shop at Tesco very often.
