Flying With a Baby on British Airways: Everything You Need to Know (2026)

By BabyTravel UK Editorial Team · Last updated April 2026

Infant lap seat policy and fees

British Airways charges 10% of the adult fare plus applicable taxes for a lap infant. Unlike budget carriers with flat fees, this percentage-based model means costs vary significantly by route. A short-haul European flight might add £20–£40; a long-haul premium route could add considerably more. Always check the infant fee when you search for your fare — it is displayed at the checkout stage.

The minimum age to fly is 7 days old (one week), which is among the most permissive of UK airlines. If flying in this very early window, carry your baby's birth certificate and a letter from your midwife or GP confirming fitness to fly. You'll also need a passport for international travel — every infant needs their own, even newborns. See our guide to getting a baby passport for the process.

BA operates a one infant per adult rule. Infants under 2 must travel as lap infants unless you book and pay for a separate seat. There is a maximum of two infants per row, and infants cannot sit in an exit row.

Pushchair and stroller rules

British Airways allows compact pushchairs in the cabin as your cabin bag allowance, provided the folded dimensions fit within 56 × 45 × 25 cm. Models that meet this include the Babyzen YOYO² (52×44×18 cm folded), the Bugaboo Butterfly (54×45×23 cm), and the Joolz Aer+ (53.5×45×21.5 cm). Stowing your stroller overhead means you have it the moment you land — no waiting at the jet bridge.

Larger pushchairs must be gate-checked at the boarding gate, free of charge. BA will return the pushchair either at the aircraft door on arrival or at baggage reclaim depending on the destination airport — ask staff when you hand it over. Use our stroller airline checker to confirm whether your model qualifies for the cabin.

Bassinet / skycot availability

This is one of British Airways' strongest family features. Bassinets (sky cots) are available free of charge on long-haul flights at bulkhead seats. Key details:

• Maximum baby weight: 12.5 kg
• Seats: bulkhead rows only (varies by aircraft — typically row 17 on Boeing 777, row 11 on A380)
• Must be pre-booked — contact BA directly after booking or request via Manage My Booking
• Bassinets are allocated on a first-come, first-served basis and fill up quickly on popular long-haul routes
• Not available on short-haul flights

If a bassinet is important to you — and it makes a significant difference on an 8+ hour flight — book it as soon as your flights are confirmed. Don't leave it until closer to travel. For long-haul destination inspiration, our guide to long-haul destinations with a baby covers the best routes for families.

Car seat policy

British Airways permits both forward and rear-facing car seats in the cabin when your child has their own seat booked and paid for. The car seat must be an airline-approved model — check BA's current approved list before travelling. BA also accepts the CARES harness (a lap belt extension) for children over 1 year and 10 kg as an alternative to a full car seat.

On long-haul flights, using a car seat for your baby gives you a significant comfort advantage — your baby can sleep in their familiar seat rather than on your lap for 10+ hours. The cost of the extra seat is often worth it for overnight long-haul flights.

Formula, breast milk, and baby food

BA flights departing UK airports follow UK government rules: breast milk, formula, and expressed milk are exempt from the 100 ml liquid restriction. You can carry as much as you reasonably need for the journey. Security staff may ask you to remove it from your bag and in some cases to taste it — this is standard procedure.

On board, BA cabin crew can warm formula or baby food in a cup of hot water on request. On long-haul flights, BA provides baby meals if pre-ordered (check options when booking or via Manage My Booking). If you're breastfeeding, the extra space at a bulkhead bassinet seat makes feeding much more comfortable. See our guide to breast milk at airport security for the full process.

Nappy bag and extra hand luggage allowance

On British Airways, your infant gets their own cabin bag allowance in addition to your adult allowance. This is the most generous structure of any of the main UK airlines — it effectively gives you an extra full-size cabin bag for nappies, milk, changes of clothes, and anything else your baby needs in-flight.

Pack the infant's bag with everything you need quick access to: nappies, wipes, a change of clothes for both of you, milk or formula, snacks if weaning, a dummy, and a couple of small toys. Our baby hand luggage checklist has the full priority list.

Booking tips: how to add an infant to a BA booking

• During booking: Select your adult ticket, then add an infant on the passenger details page. The 10% infant fee is calculated and shown at checkout.
• Request a bassinet immediately: After booking, go to Manage My Booking and request the bassinet. Alternatively, call BA directly. Do not wait — bassinet seats on popular long-haul routes book out fast.
• Seat selection: For long-haul with a bassinet, the bulkhead row is essential — you won't have a seat in front, giving you floor space and the bassinet fitting. For short-haul, an aisle seat near the front gives you easiest access and priority deplaning.
• Priority boarding: BA offers families with children under 5 priority boarding on most routes — look for the family boarding call before general boarding begins. Use it: extra time to stow bags, settle your baby, and organise yourself before the cabin fills.
• Executive Club: If you're a BA Executive Club member, Avios points can be used to offset the infant fee on Reward flights.

Our take on British Airways with a baby

British Airways is the best UK carrier for long-haul travel with a baby, largely because of the free bassinet on intercontinental routes. That one feature — the ability to lay your baby flat for several hours on an overnight flight — makes a genuine difference to how manageable the experience is. The 10% fee structure means costs vary, so it's worth running the numbers before assuming BA is expensive; on some routes it's comparable to a flat fee. Short-haul BA with a baby is solid but unremarkable — the infant cabin bag allowance is a real plus, and the option to take a cabin-sized stroller works well. The main thing to get right is the bassinet booking: do it the same day you buy your tickets.

Frequently Asked Questions

No — BA charges 10% of the adult fare plus taxes for a lap infant under 2. On short-haul European routes this is often £20–£50. On long-haul premium routes the fee can be higher. The exact amount is shown during the booking process. Jet2 is currently the only major UK airline offering free infant travel.

Can I take a stroller on British Airways?

Yes. Compact strollers within 56×45×25 cm can go in the overhead locker in the cabin. Popular cabin-approved models include the Babyzen YOYO², Bugaboo Butterfly, and Joolz Aer+. Larger pushchairs are gate-checked free of charge and returned at the aircraft door or baggage reclaim.

Does British Airways have bassinets?

Yes — on long-haul intercontinental flights only. Bassinets are free, located at bulkhead seats, and available for babies up to 12.5 kg. They must be pre-booked and fill up quickly on popular routes. Book them the same day as your tickets. No bassinets are available on short-haul European flights.

You can bring nappies, wipes, formula, breast milk, baby food, medicines, a portable changing mat, and a cabin-approved stroller.

Is British Airways good for flying with a baby?

BA is one of the better full-service options for UK families, particularly on long-haul routes. The free bassinet, infant cabin bag allowance, cabin stroller option, and priority boarding together make for a genuinely comfortable experience. The 10% fare-based infant fee is the main variable — check it at booking. For comparing BA against other airlines, see our full airline comparison.
