Flying with 5 kids: car seats, seating and what it really costs

Five tickets, car-seat approval, and how to avoid being split across the cabin.

By Emma Larsson·Last updated Jun 19, 2026

Once every child needs their own seat, flying becomes a logistics project. Here is the playbook.

Booking strategy

Sometimes splitting one booking into two saves money and unlocks better seat maps. Always check both.

Frequently asked questions

Do you need a car seat on a plane?
It is not required for children over 2 who have their own seat, but the FAA strongly recommends an approved restraint. Check your seat is labelled "certified for use in aircraft".
How much does it cost to fly with 5 children?
You pay for five seats (every child aged 2+). Splitting the booking and using child award discounts on some airlines can cut the total noticeably.
