British Airways opens bookings 355 days before departure, so if you wait for a big seasonal release you won’t find one. The window is the same whether you’re booking a seat to Madrid or a business class flight to Singapore. Here’s how the BA booking window works and how to use it.

The BA booking window: 355 days in advance
When does BA release flights? Every day at midnight GMT, British Airways opens bookings for flights departing exactly 355 days later. There’s no seasonal batch and no single date when summer 2027 appears all at once: each flight goes on sale 355 days before it departs, and the booking horizon moves forward by a day every night. Budget airlines work differently. Ryanair releases its schedule in seasonal batches, and its summer 2027 flights were already on sale by 4 October 2026. The same 355-day rule covers every kind of BA booking:
- Cash tickets
- Avios reward bookings
- Flight-inclusive packages through BA Holidays
- Short-haul European routes and long-haul flights to North America, Asia and beyond
“BA’s 355-day window rewards anyone whose dates are fixed. A Christmas trip, a wedding abroad or a school holiday flight opens at midnight GMT exactly 355 days before departure, and there’s no seasonal batch release to wait for. If your dates can’t move, work out which day your flight opens and book it on ba.com that night.”Kate Acaster, Chief Editor, Flight Tribe
How BA’s booking window compares to other airlines
The 355-day window is one of the longest of any carrier operating from the UK. Most budget airlines work on shorter timescales because they build their schedules closer to departure, though Ryanair now sells further ahead than BA. The table below shows how they compare.
| Airline | Booking window | How flights are released |
|---|---|---|
| British Airways | 355 days | Rolling daily: new flights open at midnight GMT |
| Ryanair | Up to 13 months (to 30 Oct 2027) | Two seasonal batches; summer 2027 on sale by 4 Oct 2026 |
| easyJet | Approx. 6 months | Seasonal route-by-route releases |
| Jet2 | Up to 12 months | Seasonal summer/winter programme releases |
| TUI | Up to 12 months | Seasonal summer/winter programme releases |
Booking with Avios: what the 355-day release means in practice
For members of The British Airways Club, the 355-day mark is the moment to act on reward seats. At midnight GMT, when a new flight enters the booking window, BA guarantees a set number of Avios reward seats:
- Four in Business Class
- Two in Premium Economy
- Eight in Economy
First Class Avios seats aren’t guaranteed but typically appear, sometimes close to the 355-day mark and sometimes nearer departure when BA wants to fill the cabin. On the most in-demand routes (peak summer, Christmas, school half-terms) it’s worth setting an alarm and booking at midnight. The BA website opens new flights at midnight, but calling the club line has historically been more reliable on busy routes.
How to work out your booking window today
Because BA opens flights on a rolling basis rather than in seasonal batches, there’s no single launch date to wait for. The furthest bookable date moves on by one day, every day. To find today’s booking horizon, take the current date and add 355 days. That’s the furthest point you can search on ba.com right now.
| What you want to know | How to find it |
|---|---|
The furthest bookable date today | Today’s date + 355 days |
When a specific future date goes on sale | That date minus 355 days |
How long until a new season opens | Count back 355 days from your target travel date |
The best time to book BA flights
BA uses dynamic pricing, so fares rise as seats fill. The broad rule is the earlier you book, the better your chances of a lower price, particularly on busy routes, peak dates, and long-haul flights where demand is consistent. That said, BA occasionally runs sales that can make fares cheaper than launch-day prices, particularly for travel 6-18 months ahead. See the British Airways sale dates guide for the full calendar.
| Strategy | When | What to expect |
|---|---|---|
| Book at 355 days | Day one the flight opens | Best availability, often lowest prices on popular routes. Essential for Avios bookings. |
| Book in a sale | Jan, Mar, Aug, Nov typically | Discounted cash fares for specific travel windows; often 20-30% off standard prices. |
| Book 3-6 months out | Mid-window | Good availability on most routes; fares may have risen on popular summer and peak-date flights. |
| Book last-minute | Under 4 weeks | Almost always more expensive. BA does not typically discount last-minute fares in the way some carriers do. |
British Airways sales: how to catch them
BA runs five or six named sales a year. The January sale is the biggest, typically launching in the first week of the new year across short-haul and long-haul routes. There’s usually a spring sale in February or March, a summer sale around August and a Black Friday event in November. Sales don’t change the 355-day booking window: you still can’t book beyond it. A sale cuts the cash fare for a set window of travel dates, often 6 to 18 months ahead. Our guide to British Airways sale dates has confirmed dates and what to watch for.
Everything you need to know about British Airways
Frequently asked questions
How far in advance does British Airways release flights?
British Airways releases flights exactly 355 days before the departure date. This applies to cash tickets, Avios reward bookings, and BA Holidays flight-inclusive packages.
What time do BA release flights?
New BA flights enter the booking window at midnight GMT, or 1am during British Summer Time. Avios reward seats are guaranteed to be available at this point on all routes.
Does BA release all flights at once?
No. BA releases flights on a rolling daily basis: each flight becomes available 355 days before it departs, one day at a time. There’s no single date when an entire season goes on sale.
Can I book a BA flight more than a year in advance?
355 days is BA’s standard limit, which works out to roughly 11 months and 20 days. Flight-inclusive BA Holidays packages follow the same rule; some hotel and car products can be booked further ahead by calling BA directly.
When do BA summer flights go on sale?
BA summer flights go on sale progressively throughout the preceding year, 355 days before each departure date. Flights for July and August go on sale around July and August the year before. There’s no single summer launch: routes open day by day as each 355-day window comes round.
Are Avios reward seats released at the same time as cash seats?
Yes. At midnight GMT when a flight enters the 355-day booking window, BA guarantees four Business Class, two Premium Economy, and eight Economy Avios reward seats. First Class reward seats aren’t guaranteed but usually appear at some point.
Is it cheaper to book BA flights on the day they’re released?
On busy routes, including school holidays, Christmas, and popular long-haul destinations, booking as early as possible usually gives you the best available price, as BA’s dynamic pricing means fares rise as seats sell. On quieter routes, prices can stay low well into the booking window.
When is the next British Airways sale?
See our regularly updated guide to British Airways sale dates for confirmed upcoming sales, typical timing for each, and what discounts to expect.
Does the 355-day window apply to long-haul BA flights?
Yes. The 355-day booking window applies to all BA flights, including long-haul routes to North America, the Caribbean, Asia, and Australia. On long-haul, the 355-day release matters even more: fares are higher and availability on popular routes fills faster.
