Beyond Dawlish

British Airways allows its passengers to make an upgrade to their flight after booking. They can do it through different methods, such as using Avios miles, paying in cash, or placing a bid on the airline. Passengers usually use the British Airways Upgrade with Avios option, as the miles earned by them may expire over time. If you need more information about upgrading with Avios, you can contact customer service or read the blog by Airlines Group Travel at the mentioned link.
