British Airways (BA) typically releases its flight tickets for booking 355 days in advance of the departure date. This applies to both cash bookings and "Reward Flights" (seats purchased with Avios). This nearly year-long window is one of the most generous in the industry, compared to the 330-day window common among many U.S. carriers. For savvy travelers and members of the Executive Club, the "355-day rule" is critical for securing popular routes during peak times like Christmas or school holidays. BA guarantees a minimum number of reward seats (usually 8 in Economy, 2 in Premium Economy, and 4 in Business) on every flight the moment they are released at midnight GMT. If you are looking to use Avios for a high-demand route like London to Sydney or New York, you often need to be online exactly 355 days out to snag those seats. For standard cash fares, while they are available this far out, the "best" prices are often found 4–6 months before departure rather than the very first day of release.
