If you are a BA flyer and are in the executive club:

You can top up your Avios points by converting your Tesco Clubcard (TCC) points, and Shell Drivers Club (SDC) points into Avios.

TCC's always seemed pretty pointless and barely worth the bother until I found out I could do this, it makes them massively more valuable than just getting vouchers for your shop.

Same with Shell, I work in Staines but live in Stourbridge in the Midlands so my diesel consumption is quite high and this is making a big contribution to my Avios total. You can opt to transfer TCC and SDC points automatically, they magically appear in your Avios account some time later.

Not everyone's bag, but I thought I'd mention it in case anyone was unaware.

Cheers,

Paul.
