BA lets you book reward seats "up to 355 days prior to departure", and on its own flights to and from Heathrow and Gatwick it guarantees at least eight economy, two premium economy and four business reward seats per flight. That isn't a promise of seats on your date: BA's terms say it "cannot guarantee that a Member will be able to make a Reward booking on any specific flight regardless of the time of booking", and reward bookings "cannot be waitlisted" (British Airways Club Terms and Conditions, clause 15.11, checked 13 Nov 2026). So search for your whole party, widen your dates and airports, set an alert if nothing shows, and only move points once a bookable seat is in front of you.
What we'd do first: open ba.com's Reward Flight Finder, set the number of passengers to your full party, and look at a whole month in your cabin. Write down every date that works, with the time you checked.
When BA reward seats open
BA's terms say reward bookings "may be made up to 355 days prior to departure" (clause 15.11). In practice that means a seat on a flight 355 days away is the earliest you can book it. If you want a specific date, put the 355-day mark for both the outbound and the return in your calendar. Because the outbound and return "must be booked at the same time" (clause 15.10), your return date opens later than your outbound. If your trip is a week long, you can't book the return until the return date is 355 days out, unless you start with one-way searches to see what's there.
BA also publishes a minimum. On its own flights to and from London Heathrow and London Gatwick it guarantees "at least" eight seats in economy, two in premium economy (World Traveller Plus) and four in business (Club Europe and Club World). From London City it guarantees two in business and two in economy (BA: Reward Flights, checked 13 Nov 2026).
What BA doesn't publish is when those seats are loaded, how many more are added later, or which flights get extra. Anything you read about seats appearing at a particular time of day, or a second wave close to departure, is observed behaviour, not BA policy. The Companion Voucher FAQ says only that "Reward seats could be made available at any time so keep checking" (BA Companion Voucher terms and FAQs).
Step 1: search ba.com for your whole party
BA calls its own website "the best and most up-to-date place to find all our available reward seats" (BA: Reward availability, checked 13 Nov 2026). It offers two tools:
- Reward Flight Finder: "Browse and compare availability for up to three destinations at once", searching by date range, city, country or continent. It finds British Airways flights.
- Search and book: "Check all availability and prices, including partners, for specific dates", including connecting journeys, with prices.
Use them in that order. The Finder shows which dates have seats; Search and book shows the price and whether you can actually book.
Search for the full party. If you're four, search for four. A date that shows one seat may not have four, and BA's minimums are per cabin per flight, so a family can use up most of a business allocation on one flight. If four don't show, try two plus two only if you're prepared to book separately, and read Avios for a family holiday in the school holidays first, because splitting a booking has its own risks.
Be flexible on dates. Look a week either side. Peak and off-peak dates cost different Avios, and BA lets you mix them on one booking (BA: Reward Flights).
Try nearby airports. Heathrow, Gatwick and London City each have their own minimums, and some destinations have more than one airport. If you live outside London, check whether a connection is available; Reward Flight Saver from regional airports explains how connections are priced.
Try one-way searches. A one-way reward costs 50% of the return (clause 15.8), so search each direction separately to see where the gaps are. BA's FAQs say you "can combine cabins within your booking", for example economy out and business back, depending on availability (stated on BA's Reward Flights page in its Avios-only flights FAQ).
Step 2: check partners when BA shows nothing
When you search, BA says it "will show availability on British Airways first", then "availability with partners for this flight and on destinations we don't operate or have availability". Partner reward seats are "subject to the availability determined by the airline partner" (clause 15.11). If you need help with a specific partner, BA says to call its contact centre.
Some airlines that use Avios have their own reward searches, and these can show different seats or different charges:
- Iberia, Qatar Airways, Aer Lingus and Finnair run their own programmes using Avios. Our Iberia and Qatar for cheaper fees guide explains how to move Avios between them and the time limits, such as BA's rule that an Iberia account must be at least 90 days old before you can combine Avios.
- Don't move Avios on a hunch. Moves between programmes can't always be reversed. Confirm the seat in the partner's own search first.
Step 3: set an alert
ba.com doesn't let you waitlist a reward ("Reward bookings cannot be waitlisted", clause 15.11), so if nothing shows, your choices are to keep checking yourself or to use an independent alert service. These services aren't run by BA. They check availability on their own schedule and email or message you when they detect a change. Their results can be out of date, so always confirm on ba.com.
Two examples, as each describes itself on its own website (checked 13 Nov 2026, 21:01 Lima; Credit Club has no affiliate arrangement with either):
- Reward Flight Finder says it shows "the full year of availability for any British Airways and Iberia route in one Search" and covers "all direct flights operated by the airline chosen". Its pricing page lists a free Bronze tier (economy only, one alert, checked daily), Silver at £3.33 a month billed annually (five alerts, hourly) and Gold at £6.66 a month billed annually (20 alerts, "Instant"). It says you book with the airline, not through the tool.
- seats.aero says it is "Not affiliated with any airline" and that its "Data is periodically refreshed and might not be up to date". Its home page says searches and alerts for flights in the next two months are free, and that PRO, at $12.99 a month, opens up to a year of availability.
Prices and features change, so check the provider's own page before paying. We haven't tested whether either tool catches every release, and neither can guarantee a seat.
If you'd rather not pay, a manual routine works: set a calendar reminder for the 355-day mark, then check the Finder for your dates at different times of day for a week or two.
Step 4: what to record before you move any points
When a seat shows up, don't transfer points straight away. Write down:
- Flights, date and cabin for every passenger, both directions.
- The Avios and the cash shown on the payment page, for the full party, and whether it's a Reward Flight or an Avios & Money option.
- The date and time you checked (screenshots help).
- Whose account is booking. BA's terms say reward bookings "can only be requested by the member who holds the account or an individual nominated" under clause 3.13 (clause 15.3). In a household account, rewards can only go to household members or people on the Family and Friends list (clause 18.1.15).
- How long your transfer takes. Amex UK says transfers to BA happen instantly, but your first transfer needs your account verified, which Amex says can take "up to 14 days". See Amex Membership Rewards UK transfer partners.
- The voucher, if you're using one. A Companion Voucher must be applied when you book; it can't be added afterwards.
Then move only what you need and book straight away. If the seat vanishes in between, read BA reward seat shows but won't book before moving more.
BA reward seats: FAQs
Can I book the outbound now and the return later?
Not as one return reward: BA says outbound and return "must be booked at the same time" (clause 15.10). You can book two one-way rewards, each at half the return price.
Is there a deadline close to departure?
Yes. Reward bookings must be made "no less than 24 hours prior to the intended day of departure" (clause 15.5).
Do alert tools book for me?
No. Reward Flight Finder says you book with the airline. Check the seat and price on ba.com.
Is a seat guaranteed if I have enough Avios?
No. BA's terms say it can't guarantee a booking on any specific flight. See how Avios pricing works for how prices change by date.
