Search for all four seats from your first search, in the cabin you want, on the dates you need. Then work out what the trip costs per person, counting Avios and cash. Children aged 2 and over pay full Avios. A BA Amex Companion Voucher covers two seats for one person's Avios, and two vouchers of the same type can go on one booking, so four people pay two people's Avios. Either way you still pay taxes, fees and charges for everyone. Reward Flight Saver fixes the cash on eligible BA flights, but the long-haul trips here may not qualify, so read the charges on screen. Have fallback dates ready, because school holidays are the busiest weeks of the year. If four seats won't show together and you split the family across two reservations, put an adult on each. Each reservation can still be changed, cancelled or rescheduled on its own, even if BA links them, and the second pair of seats can disappear before you finish paying for it.
What we'd do first: open ba.com's Reward Flight Finder, enter 2 adults and 2 children (or your real party), choose economy, and look across the whole holiday, not just the first Saturday.
Why four seats is harder than two
A search for one seat tells you nothing about a second, third or fourth seat on the same flight. The engine only shows what's free for the party size you enter, so enter all four from the start.
BA publishes a minimum number of reward seats on its Heathrow and Gatwick flights: "at least" eight in economy, two in premium economy and four in business (BA Reward Flights, checked 13 Nov 2026). That's a minimum at release, not what's left by the time you search. Note what it means for a family of four:
- Economy: the minimum allocation is eight, so four is possible if you search early.
- Premium economy: the minimum is two, so four seats depend on BA releasing more than the minimum.
- Business: the minimum is four, so a family of four would need the whole minimum allocation.
The CAA's trip-planning advice points out that prices tend to be higher in the school holidays and suggests being flexible with dates where you can (CAA: planning your trip, checked 13 Nov 2026). Reward seats aren't priced like cash fares, but the competition for them is just as real.
Where BA flies: Orlando and the Caribbean
- Orlando: "British Airways flies direct to Orlando International Airport from London Gatwick" (BA: flights to Orlando, checked 13 Nov 2026).
- Barbados: "We fly to Barbados from London Heathrow and London Gatwick" (BA: flights to Barbados, checked 13 Nov 2026). Two London airports give you two chances to find four seats.
Both pages say families travelling with younger children can check in one car seat and one fully collapsible pushchair, on top of the normal allowance.
If you're not in London: Virgin Atlantic also flies to Orlando, from London and Manchester, with its own Virgin Points rewards. Our Virgin Points Upper Class guide covers how Virgin prices seats.
How the Companion Voucher works for a family of four
The BA Amex Companion Voucher lets the cardholder book a second seat for no extra Avios. The member pays "the Avios for one person and the taxes, fees and charges for both". The free BA Amex card's voucher is for economy only and lasts 12 months. The Premium Plus voucher works in any cabin and lasts 24 months. You must apply the voucher when you book; it can't be added later. Full rules are in how the BA Companion Voucher really works.
For four people, there are two ways a voucher can help:
- Two vouchers of the same type on one booking. BA's voucher terms say: "A maximum of two Companion Vouchers can be redeemed at any one time on the same booking e.g. 2 Avios reward fares plus 2 Companion Voucher tickets" (clauses 9 and 15), and that "Only Companion Vouchers of the same type can be combined" (clauses 10 and 16). BA's FAQ adds that two vouchers of the same type "will allow a maximum of 4 passengers to travel (excluding infants under the age of 2 years old)" (BA Companion Voucher terms and FAQs, checked 13 Nov 2026, 21:26 Lima). So four people can travel for two people's Avios, paying charges for all four. Each voucher's cardholder "must travel" (clauses 7 and 13), and BA's examples describe one cardmember holding both. If the vouchers belong to two cardholders, such as both parents, we couldn't find wording confirming they can share a booking: check before committing.
- One voucher plus two full-Avios seats. We couldn't find BA wording that confirms a booking with one voucher can also include two more passengers paying the normal Avios price. This stays open until BA confirms it. If the search won't let you add them, you'd need a second reservation, following the split-booking rules below.
One more check: Reward Flight Saver with a voucher. BA's Conditions of Use say BA may decide that Reward Flight Saver can't be used, in whole or part, with Companion Vouchers. Read the charges at checkout, not the RFS price you expected.
Supplementary cardholders don't earn a voucher (clause 2).
Children: the rules that change your booking
- Children under 14 must travel with someone 16 or over. BA's Conditions of Carriage say: "We will not carry you if you are aged under 14 at the date of travel and are not travelling with someone aged 16 or older on your booking or on a linked booking." (BA General Conditions of Carriage, clause 5d4.) If you split the family across two reservations, put an adult on each.
- Seats together aren't guaranteed. BA "cannot guarantee that you will be able to sit in any particular seat" (clause 5e2). The CAA says airlines "should aim" to seat children under 12 in the same row as, or no more than one row or aisle from, their accompanying adult.
- Children aged 2 and over pay full Avios. The British Airways Club terms say: "Children (2 years of age or older) and infants who require their own seat will be assessed the full Avios for the relevant destination" (British Airways Club Terms and Conditions, clause 15.4, checked 13 Nov 2026, 21:26 Lima). There's no child discount in Avios, so a family of four pays four lots of Avios unless a voucher covers some seats.
- Lap infants pay 10%. The same clause says infants under 2 "will travel for ten percent of the Avios required for the member's flight reward if they do not have their own seat". avios.com adds that the infant pays "applicable taxes, fees, and charges" and can be added by phone more than 24 hours before departure (avios.com help, checked 13 Nov 2026). Infants don't count towards the four passengers on a two-voucher booking, according to BA's voucher FAQ.
What a family of four pays: worked example
Two adults and two children (aged 2 or over, so all four pay full Avios), economy, London–Orlando return in the school holidays. The prices are hypothetical, not BA quotes: 60,000 Avios + £200 per person return, and a cash fare of £900 per person. We value Avios at an assumed 1p each.
| Option (four people, return, economy) | Avios | Cash | One number at 1p | Per person |
|---|---|---|---|---|
| Four reward seats, no voucher | 4 × 60,000 = 240,000 | 4 × £200 = £800 | £2,400 + £800 = £3,200 | £800 |
| One Companion Voucher (two seats for one Avios price) + two full seats (one booking not confirmed by BA; may need two reservations) | 3 × 60,000 = 180,000 | £800 | £1,800 + £800 = £2,600 | £650 |
| Two Companion Vouchers of the same type on one booking (2 Avios reward fares + 2 voucher tickets) | 2 × 60,000 = 120,000 | £800 | £1,200 + £800 = £2,000 | £500 |
| Cash fare (hypothetical) | 0 | 4 × £900 = £3,600 | £3,600 | £900 |
The voucher doesn't cut the cash, because everyone pays taxes, fees and charges. It only saves Avios. The cash is the same in every reward row. To check whether the Avios are worth using at all, run the two-number test in when cash beats Avios. Peak and off-peak dates, and Avios + money options, are explained in Avios pricing explained.
How to search for four seats, step by step
- Enter your real party. Two adults and two children (and an infant, if any) before you look at dates.
- Search the whole holiday. Use the Reward Flight Finder's date range, and check both Gatwick and Heathrow for Barbados.
- Search each direction separately. Reward flights can be booked one way, and peak and off-peak dates can be mixed. If outbound works on Saturday and the return only on Monday, that may still suit you.
- Add the voucher (or two of the same type) at the start. It must be applied when you book.
- Write down what you see. Flights, Avios, cash per person and in total, plus the date and time you checked.
- If you must split, do it last and be ready to pay for both. Search for all four first. Only if four won't show together, split into two reservations with an adult on each, and pay for the second as soon as the first is done: the second pair of seats can disappear before that purchase is complete, so accept that risk before you start.
- Book straight away. Seats can go between search and payment. BA lets you book "up to 355 days ahead of the departure date" (BA help), and the school-holiday dates are known well before that.
When four seats won't show: fallback options
Change one thing at a time:
- Move by a day or two. Search the days either side of your first choice, including midweek; a different day can have seats when your first choice doesn't.
- Switch airport. For Barbados, try both Gatwick and Heathrow.
- Switch island or city. Search the other Caribbean islands BA flies to, or Orlando instead of the Caribbean (or the reverse).
- Mix cabins by direction. On BA reward bookings, "You can combine cabins within your booking", for example economy out and a higher cabin back. Price both and decide whether it's worth it.
- Split the family into two reservations of two. Only after a search for all four has failed. Put an adult on each reservation. Be ready to pay for the second reservation immediately after the first, and accept that the second pair of seats could disappear before that purchase is complete. You may not sit together.
- Book at release. Plan the holiday 355 days out if you can.
- Have a cash plan. If no reward seats appear, compare the cash fare, or keep Avios for a different trip.
Two reservations is a trade-off: more chances to find seats, less protection. Even if BA links them, each can be changed, cancelled or rescheduled independently, and each person pays the fees. BA charges £35 per person to change a reward flight, up to 24 hours before departure, and £35 per person to cancel, with the Avios returned (avios.com). If the second pair of seats goes before you've paid, or one reservation is later cancelled, the other stands on its own, so you could be left with half a holiday. Decide in advance what you'd do: cancel the first (and pay the fees), or look for two more seats on another flight.
Reward Flight Saver: what it covers and what it doesn't
Reward Flight Saver (RFS) is BA's fixed-cash option on selected BA-operated flights. To be eligible, you must have earned at least one Avios in the 12 months before you book. RFS covers selected BA flights only, not partners, franchises or codeshares, and its prices "may vary by date". One-way bookings pay 50% of the return price, and if the actual taxes are lower you pay those instead (BA Conditions of Use, checked 13 Nov 2026).
Whether a long-haul family route is covered changes over time. Read the cash for all four passengers on the payment page and don't plan on a figure you haven't seen. For short-haul family trips from outside London, see Reward Flight Saver from Manchester, Edinburgh and Belfast.
Family trips on Avios: FAQs
Can I use the voucher for the children?
The companion can be anyone travelling with the cardholder on the same flights and in the same cabin; see our voucher guide for the exact clauses.
Do children get a discount in Avios?
No. Children aged 2 and over, and infants with their own seat, pay full Avios (BA Club terms, clause 15.4). Lap infants pay 10% plus their charges.
Can two vouchers cover a family of four?
Yes, if they're the same type: "2 Avios reward fares plus 2 Companion Voucher tickets". If two different cardholders hold them, check with BA first.
Should we split into two reservations?
Only if a search for all four has failed. Put an adult on each reservation (BA clause 5d4). Even if BA links them, each reservation can still change, be cancelled or be rescheduled independently, and the second pair of seats can disappear before the second purchase is complete, so be ready to pay for both immediately and accept that risk.
Is a BA holiday package better?
Sometimes, especially when reward seats are scarce. We'll cover it in the BA Holidays Avios guide.
