What age can a child fly for free?

Children under 2 years old can fly as a 'lap infant' for free on domestic US flights (including Hawaii). International flights charge 10% of the adult fare for lap infants. Once a child turns 2, they need their own purchased seat. Pro tip: if your child turns 2 during a trip, they need a ticket for the return flight even if they flew free on the outbound. Some parents book a seat for infants anyway for the extra space and ability to use a car seat.

Should I bring a car seat on the plane?

For children under 2 who have their own seat, the FAA recommends (but doesn't require) an approved car seat. For children 2-4, a car seat on the plane is safer than a seatbelt alone and also provides a familiar sleeping environment. The downside: car seats are heavy and bulky. A good compromise is the CARES harness ($75) — an FAA-approved restraint that weighs 1 pound and fits in your purse. Then gate-check your car seat for free.

Surviving Long Flights with Kids: A Parent's Survival Guide

Long Flights with Kids Aren't as Bad as You Think

I've booked hundreds of family trips to Hawaii, Fiji, and Europe for Bay Area families, and the #1 fear is always the flight. Parents imagine 5-10 hours of screaming, spilled juice, and judgmental stares from business travelers. Here's the truth: with preparation, long flights with kids are manageable — and the vacation on the other side makes every minute worth it.

Most kids under 10 will happily entertain themselves for hours if you've packed the right supplies. And most fellow passengers are far more understanding than you expect. The families who have the worst flights are the ones who didn't prepare — not the ones with 'difficult' kids.

Strategies by Age Group

Different ages need different approaches.

Flight Strategies by Age

Under 2 (Lap Infant)

Feed on takeoff/landingNurse or bottle-feed during ascent/descent to prevent ear pain. Bring a carrier for walking the aisle. Book a bulkhead seat if possible.

Ages 2-5

New toy every 30 minPack a bag of small, wrapped 'presents' — one per 30 minutes. Sticker books, Play-Doh, magnetic drawing boards. Tablet loaded with downloaded shows as backup.

Ages 6-9

Screen time is your friendThis is the age where tablets save flights. Download movies, games, and audiobooks before departure. Bring kid-sized headphones. A window seat provides entertainment too.

Ages 10+

They're basically adultsHeadphones, phone/tablet, a book, and snacks. They can largely entertain themselves. Biggest challenge is keeping them from draining your portable charger.

The Ultimate Family Flight Carry-On

Pack these items and you'll survive any flight length.

Must-Pack Items for Family Flights

Loaded tablet with offline content

Download 4-6 hours of content PER CHILD before departure. Netflix, Disney+, and YouTube all allow offline downloads.

Kid-sized headphones

Airline headphones don't fit small heads. Bring volume-limiting headphones ($15-25) — protects hearing and prevents blasting sound.

Snacks (lots of them)

Airline snack service is unpredictable. Pack goldfish crackers, fruit snacks, granola bars, and something special (candy for emergencies).

Change of clothes in carry-on

For kids AND one parent. Spills, accidents, and motion sickness happen. A fresh outfit salvages the situation.

Empty water bottles

Fill after security. Stay hydrated — cabin air is extremely dry and dehydration causes crankiness.

Portable charger (20,000mAh+)

Enough to charge 2-3 devices. One dead tablet can derail your entire flight plan.

Pro Tips from Seasoned Family Travelers

These strategies come from years of client feedback and personal experience.

Pro Tips

•Book flights during sleep times — red-eye flights to Hawaii or overnight flights to Europe let kids sleep through most of it
•Request bulkhead or exit row seats when possible — extra legroom means extra play space for toddlers
•Gate-check your stroller — use it until boarding, then gate-check for free. It'll be waiting at the jet bridge on arrival
•Walk the aisle every 1-2 hours — kids need to move. A trip to the bathroom is an adventure at 35,000 feet
•Bring a special 'plane treat' they don't normally get — the novelty factor keeps them engaged longer than familiar items
•Don't stress about screen time limits on travel days — one day of extra tablet time won't hurt anyone
•Benadryl is NOT a sleep aid for flights — it makes some kids hyper. Test any medication before travel day
•Tell the flight crew you have young kids — they're often happy to give extra snacks, coloring pages, or wing pins
