Traveling with kids: What You Need to Know Before You Fly

Flying with kids for the first time? Whether you're a parent, grandparent, or guardian, it's a mix of excitement, logistics, and (sometimes) chaos. But with the right prep, you can make the journey smooth for everyone onboard.

Here’s a practical guide to help you plan ahead and avoid surprises.

1. How Old Should a Baby Be to Fly?

Most airlines allow babies onboard from around 7 to 14 days old, but it varies. Medically, it’s best to wait until at least 2 months, when babies start developing immunity. Always check with your airline in advance to confirm the age limit.

2. Travel Documents for Children

• Domestic flights: In some countries (like the U.S.), children may not need ID for domestic flights.

• International flights: Every child will need their own passport. Some destinations also require visas, immunization records, or travel authorizations.

Don’t leave it to the last minute — get documents sorted well before takeoff.

3. Consent to Travel (Especially for One-Parent or Non-Parent Guardians)

If a child is:

• Traveling solo

• Flying with only one parent

• With an adult who isn’t a legal guardian

...you may need written permission. Some countries require notarized consent letters, so check ahead to avoid last-minute issues at the airport.

4. Unaccompanied Minors

Most airlines allow kids aged 5 to 14 to fly alone with a special service (and fee). Staff guide them through boarding, layovers, and hand them off safely at the destination.

Children under 5 usually cannot fly alone. Teens aged 15–17 may fly solo without the service, but it’s optional depending on the airline.

5. Skip the Airport Lines

Parents, rejoice: many airports offer priority lines for families with kids (especially under 12). Use them! You might also get priority boarding — just ask the staff.

6. Baby Formula and Liquids at Security

The 100ml liquid rule doesn't apply to baby needs:

• Breast milk, formula, toddler drinks = allowed

• Bring ice packs or cooler bags for storage

• Be prepared for inspection (manual checks or sniff tests)

Tip: Use clear, labeled bottles to make the process easier.

7. Stroller and Car Seat Check-In

Most airlines let you check one stroller or car seat per child for free. Tag it at check-in, and pick it up at the gate or baggage claim.

8. Seating & Onboard Setup

• Lap seats: Under 2 years = can sit on your lap with a special infant belt (cheaper ticket)

• Own seat: Bring an approved child seat if you want them in their own space

• Seating together: Let the airline know in advance. In many regions (like the UK), you should be seated next to your child at no extra cost.

9. Know What the Airline Provides

Check with the airline about:

• Changing tables on board

• Sterilized water or bottle-warming services

• Infant bassinets (free, but limited availability)

Not all airlines offer the same support — check ahead.

10. Yes, Children Also Get Flight Compensation

If your flight was delayed, canceled, or overbooked, your child might also be eligible for up to €600 in compensation — just like an adult.

The only catch: if the child flew on a completely free ticket, they may not qualify. But if the ticket was paid (even discounted), they’re likely eligible.

Enjoy Your Trip (and Know Your Rights)

Traveling with kids takes extra effort, but the memories are worth it. A bit of planning goes a long way toward avoiding mid-air stress.

And if your trip doesn’t go as planned? Remember: flight disruptions happen, but that doesn’t mean you have to just accept it. You may be entitled to up to €600 — and we’ll handle the claim for you.
