How to make your Avios go further

If you're based in the UK then there's a way to make your Avios go even further, and that's through a Companion Voucher. I've written extensively about these amazing vouchers. They're not free in that you have to spend at least £15,000 on an Amex Card, but they're absolutely worth it. Read my guide on is a BA companion voucher worth it? to understand how to use a 2-4-1 voucher. On top fo that, you can also use a Barclays Cabin Upgrade voucher to reduce the number of points needed. You can get these by either being a Barclays Premier customer, or by hitting a spend level on a Barclaycard.

How can you search for reward seat availability?

BA offers a number of ways to search for reward seats: their "Reward Flight Finder", their in-app "Reward Flights" section and just making a dummy booking. There are also third party tools that you can use, although I've managed to find plenty of seats without having to pay for a platform. I wrote about the best (and worst) ways to search for Avios availability. If you're looking to book seats to a popular destination then planning ahead is critical: seats become available 355 days before the flight date.
