Flying as a family drains a budget fast — three or four tickets, baggage and extra fees add up to one uncomfortable surprise. The good news is that most of a family's ticket cost shrinks with planning. This guide shows where the hidden costs hide and how to save real money before you fly as a family.
📅 Book early and avoid the school-holiday peak
The biggest trap for families is school holidays — June to August, New Year and spring breaks, when prices peak. If your children are under school age, use that flexibility and fly in the low season.
Make family bookings early — 4 tickets bought at the last minute cost far more than 1. Shifting your dates by a day or two often lowers the whole fare — see flexible-date savings and when to buy tickets.
👶 Child and infant fares — what to know
- Infant (0-2) on a lap: often ~10% of the fare plus taxes, with no separate seat
- Child (2-11): usually the adult fare on low-cost carriers (Wizz Air, Pegasus), with a small discount on full-service airlines
- A stroller and a separate infant seat often count as free checked items — check the rules
- Carry a birth certificate or passport to prove the child's age
💺 The sit-together fee — how to avoid it
Low-cost carriers often split a family up and charge a seat-selection fee to sit together. It is one of the most irritating hidden costs. The trick: many airlines have a policy of seating a young child next to a parent for free — check this at online check-in.
If you're automatically split up, don't pay right away — at online check-in or at the gate, the crew will often reseat you together for free. The logic of seats is in the seat selection strategy.
If sitting together is critical (a small child), buy at least one paid seat by the window — the crew will usually move the rest of you next to it.
🧳 Baggage — share it, don't buy separately
Baggage is a big cost for a family. Instead of 4 separate small suitcases, take 1-2 large checked bags and share them — it's often cheaper. Many airlines don't pool weight, but the per-bag fee still adds up.
Pack your carry-on wisely — the packing tips and baggage-fee savings will help. A stroller and a car seat are almost always free — use that.
✈️ Low-cost or full-service for a family
A low-cost base fare is tempting, but for a family baggage, sitting together and meals add up. Sometimes a full-service airline, where baggage and seats are included in the price, ends up cheaper for a family — calculate the full price, not just the base. See the comparison in low-cost vs full-service airline.
For a large family, a group booking is also an option — see the group booking guide. The logistics of flying with children are in the flying with kids guide.
