British Airways is now offering Avios subscriptions, letting you buy a fixed amount of points each month. You can choose from different tiers, getting you between 20,000 and 200,000 Avios annually.

Why should you care? Well, if you're based in the U.K., you could snag Avios for as little as 0.99 pence each with the current promotion. Even better, U.S. members might be able to get them even cheaper. It's a good idea to check the math for your specific situation.

The big question is: is it worth it? It all boils down to your travel goals and how you usually use Avios. If you've got a specific redemption in mind (think business class to London!), crunch the numbers to see if subscribing saves you money compared to buying Avios outright or earning them through everyday spending. Just be sure to compare the pence/Avios ratio against typical redemption values.
