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.

More on using Avios for Miami flights

Miami is a popular destination from London which is why BA use their oversized A380 twice a day from Heathrow. That means a large Business Class cabin (97 seats) however they are the old style Club World seats and not the new Club Suites. That means a poorer experience in that cabin. The aircraft also has a large first class cabin, with fourteen seats. The sheet volume of seats on the A380 means that this is an easier route to grab availability for if you can book well in advance. Generally there are a reasonable number of business class seats available, whilst First availability is more limited. At the time of writing there are no first class seats available for the next twelve months, and if you're looking for a premium experience you'll want to be in the First cabin rather than the dated Business seat. What is interesting is the changes that will take place on this route. BA has just launched their new Miami lounge, which has been a long time coming. It's an attractive space, and a big upgrade on the contract loung they were using. An even more singnificant change is the upgrading of the A380, which starts mid-2026. That will bring a brand new First cabin (the A380 will be the first plane to get this) and the Business cabin will have all the seats change to the new Club Suite.
