BA releases seats 355 days ahead at midnight GMT
There is no public British Airways “availability tool” that shows a live count of reward seats across every future date — only BA’s own Reward Flight Finder and specialist alert services can do that. What you can pin down with certainty is the single most important date in the whole process: the day the seats first become bookable.
Enter your departure date above and this tool counts back 355 days to the exact moment BA loads its guaranteed reward inventory. For the toughest routes, being ready at that moment is often the difference between a business-class seat and a “no reward seats available” screen.
Seats release at midnight GMT — which becomes 1am UK timeduring British Summer Time (late March to late October). Set your alarm for the UK-adjusted time, not just “midnight”.
On long-haul flights, British Airways commits to a minimum number of reward seats the moment the 355-day window opens. Knowing these numbers tells you how much competition you face.
| Cabin | Heathrow / Gatwick | London City |
|---|---|---|
| Economy (World Traveller) | At least 8 | At least 2 |
| Premium Economy (World Traveller Plus) | At least 2 | — |
| Business (Club World) | At least 4 | At least 2 |
| First | Not guaranteed | — |
These are minimums, not maximums — a quiet route can open with more. First Class is never guaranteed at release; see our First Class Avios availability guide for how those seats behave.
The British Airways Amex Premium Plus companion voucher unlocks an extra pool of Club World reward seats that never show on public searches. It is the single biggest availability advantage in the programme.

Once you know your release date, you still need eyes on the inventory. These are the tools that do the watching — the free official ones you book through, and the specialist services that alert you the instant a seat opens.
BA Reward Flight Finder & the Avios calendar (free)
The only places you can actually book. The Avios.com calendar shows a whole month at a glance for BA, Iberia and Aer Lingus — read our availability calendar walkthrough.
Reward Flight Finder, SeatSpy & Seats.aero (alerts)
These scan a full year of dates and message you the moment a seat appears — whether at the 355-day release or when a cancellation frees one up. Start on their free tiers.
Always confirm on BA before you act. Third-party tools work from cached data that can lag reality. Verify a seat is genuinely bookable on the British Airways site before you transfer any points.
Missing T-355 is not the end. BA’s reward inventory is dynamic, so seats reappear throughout the year. There is no waitlist to join — see our guide to the (non-existent) BA waitlist — so a standing alert is your best friend.
