Yes, you can combine Avios and cash through a feature known as Avios & Money, primarily offered by British Airways, Iberia, and Qatar Airways. This option allows you to reduce the total number of Avios required for a Reward Flight by paying a larger cash portion, or conversely, to "top up" your Avios balance if you don't have enough for a full redemption. When booking a flight on the British Airways website, you will often be presented with a sliding scale of options (e.g., 10,000 Avios + $100 vs. 5,000 Avios + $250). This is particularly useful for travelers who earn Avios slowly but want to benefit from the program's value. It is important to distinguish this from "Avios Part Payment," which allows you to use small amounts of Avios to get a discount on a standard cash commercial fare. In 2026, the value of these redemptions varies, so it is wise to calculate the "cents per Avios" to ensure you are getting a fair exchange. Generally, using Avios for a full Reward Flight (only paying taxes/fees) offers the best value, but the cash-plus-points option provides essential flexibility.
