Do Babies Fly Free? Infant Fees by UK Airline
From each airline's own help, fees and baggage pages, checked 17 October 2026. Prices and rules change, so check the price shown when you book.
Short answer: usually not. Of the five UK airlines we've checked in depth, only Jet2 lets babies under 2 fly free (since 22 August 2025). easyJet charges £25 per infant, per flight, and Ryanair charges £25 per infant, per one-way flight, so a return costs £50 on either. British Airways charges a lap infant fare that is a percentage of the adult fare, and TUI says its infant charge varies by route and is shown when you book. On long-haul, Virgin Atlantic charges 10% of the adult fare for a lap baby. On every one of them, a pushchair and a car seat go in the hold free.
Infant fees at a glance
| Airline | Baby on your lap (under 2) | Return trip, one lap baby | Youngest age to fly | Baby's own bag allowance |
|---|---|---|---|---|
| Jet2 | Free for under-2s on the date of the flight (Jet2 news, Aug 2025) | Free | Over 7 days without clearance; 2 to 7 days with Jet2's approval; not under 2 days | No bag of their own, but an extra 10 kg is added free to the adult's 22 kg hold bag |
| easyJet | £25 per infant, per flight (easyJet fees) | £50 | 14 days | One changing bag up to 45 × 36 × 20 cm, under the seat |
| Ryanair | £25 (or €25) per infant, per one-way flight (Ryanair fees) | £50 | 8 days | One baby bag up to 5 kg and 45 × 35 × 20 cm, on top of your own allowance |
| British Airways | An infant fare, which BA says is a percentage of the adult fare; no fixed figure published (BA tickets) | Depends on your fare | 48 hours (BA recommends waiting a week) | One 23 kg checked bag (not on Basic fares), plus an extra cabin bag for in-flight essentials |
| TUI Airways | An infant charge that varies by route and flight length, shown when you book (TUI) | Depends on route | More than 14 days | 10 kg checked bag on a TUI package flying both ways with TUI; none on flight-only; no hand luggage |
| Virgin Atlantic | 10% of the adult fare, plus taxes, fees and charges (Virgin Atlantic) | 10% of the adult return fare, plus taxes | Not stated on Virgin's own pages; ask before booking | One checked bag (not on Economy Light) and a 6 kg cabin bag |
A worked example: a family of two adults and one baby flying a return trip pays £0 for the baby on Jet2 and £50 on easyJet or Ryanair, on top of the adults' fares. On BA and TUI, look at the infant line in the price breakdown before you pay.
What's free on every airline here
- Pushchair and car seat: all five carry baby equipment in the hold free. easyJet, Ryanair, Jet2 and BA each allow two items per baby or child, such as a pushchair plus a car seat or travel cot, and TUI checks your pushchair and car seat in free on package and flight-only bookings. See pushchair allowance by airline for the details.
- Baby milk and food: at UK airports you can take enough baby milk, baby food and sterilised water for the journey in your hand luggage, beyond the usual liquid limit (GOV.UK).
If your baby turns 2 during the trip
This catches people out, and each airline handles it differently:
- Jet2: the free infant rule applies to babies under 2 on the date of the flight, so the flight home is judged on that day's age.
- easyJet: if your child turns 2 while you're away, you need to book them a separate seat.
- Ryanair: the baby must be under 2 on both flights for the infant fee. If they turn 2 during the trip, Ryanair says they pay the full fare for the return flight, and suggests booking two one-way flights instead of a return.
- British Airways: your child needs their own seat on every flight on or after their second birthday, but BA says it won't charge extra: you pay the infant fare for the whole journey. BA arranges this for you rather than the website.
- TUI: on a package holiday, your child travels as an infant only if they're still under 2 on the day you fly home; if not, you book and pay for a child place. On flight-only, TUI goes by the age on the day of travel.
Buying your baby their own seat
Every airline here lets you buy an under-2 their own seat instead of having them on your lap. Your baby then needs an approved car seat on board, and the fare is no longer the infant fee:
- easyJet: infant seats can't be booked online; contact easyJet's Customer Service team. A baby with their own seat gets an adult's bag allowance.
- Ryanair: a car seat can only be used on board if you've bought your under-2 a seat.
- Jet2: buy a seat at the appropriate fare and contact Jet2's Customer Service team for advice and charges first.
- British Airways: the baby pays a child fare and travels in an approved car seat or BA's AmSafe system. You can't book this online.
- TUI: pay extra for a seat, which comes with a full baggage allowance; contact TUI to check availability and prices.
Travelling alone with two under-2s? On easyJet, BA and TUI one baby can be on your lap and the other needs their own seat with a car seat. Ryanair allows only one infant per adult.
Want to fly lighter, or not at all?
On Eurostar there's no infant charge at all: under-4s travel free on an adult's lap. See Eurostar with a baby, or take a cruise from a UK port with P&O Cruises or Cunard and skip the airport entirely.
