Family Travel Baggage Tips: Save on Bags with Kids

Family baggage tips for flying with kids. How to maximize free bag allowances, which airlines give free bags for children, and how to pack light.

The Family Baggage Challenge

Flying with kids is expensive before you count bags. Multiply a $35 checked bag fee across a family of four on a round trip and you've spent $280 just for bags — more than some budget airfares. Add a stroller, a car seat, and the reality that children require more stuff than adults, and baggage costs can easily consume 20–30% of a family travel budget.

The good news: there are real strategies to cut these costs significantly, and some of the best perks — like free stroller check — are already built into airline policies and are simply not well advertised.

Strollers and Car Seats: Almost Always Free

This is the single most important thing families need to know about airline baggage: strollers and car seats are free to check on virtually every major US airline, regardless of fare class.

This applies to:

  • Delta, United, American, Southwest, JetBlue, Alaska, and most other major US carriers
  • Basic Economy tickets where even standard checked bags cost extra
  • Lap infants who haven't paid for a seat

You can check a stroller at the ticket counter, or — much more conveniently — you can gate check it. Gate checking means you bring the stroller all the way to the jet bridge, fold it up, and hand it to the ground crew just before boarding. When you land, it's returned to you at the jet bridge (not baggage claim), often before you've even walked through the arrival gate.

Gate checking is almost always preferable for families with children who need the stroller up until boarding and again the moment they step off the plane.

Tips for gate checking a stroller:

  • Use a stroller bag or cover to protect it from damage in the cargo hold
  • Remove any attachments or accessories that could snag and get lost
  • Tag the stroller with your name and contact info
  • Fold it before reaching the jet bridge to speed up boarding

Infant and Lap Child Allowances

Lap infants — children under 2 who fly without their own seat — typically receive the following for free on domestic US flights:

  • One collapsible stroller
  • One car seat

On international flights, the allowance is often more generous. Many carriers include a checked bag for lap infants on international routes because infant international fares (usually 10% of the adult fare) are designed to include some luggage capacity.

Check your specific airline's infant baggage policy before flying. The policy for lap infants is separate from the policy for children with purchased seats.

Which Airlines Give Families the Best Bag Deals

Southwest Airlines

Southwest has traditionally been the most family-friendly option for checked bags: every passenger (including children with purchased seats) receives two free checked bags. This has been a significant advantage for families who need to bring more luggage. For a family of four, that's potentially eight free checked bags total — worth $280–$400 compared to network carriers.

Major US Network Carriers (Delta, United, American)

On Delta, United, and American, children with purchased seats pay the same checked bag fees as adults. If a co-branded credit card covers bag fees for traveling companions on the same reservation, that benefit typically extends to children's tickets as well — check your specific card's terms.

International Full-Service Carriers

Emirates, Lufthansa, Qatar Airways, and most other full-service international carriers include checked bags in their economy fares for all passengers, including children. A family flying Emirates to Dubai with economy tickets for everyone will have bags included for everyone — no separate fee per person.

Budget Carriers (Spirit, Frontier, Ryanair)

Budget carriers charge bag fees per bag regardless of passenger age. Children's tickets receive the same personal item allowance as adult tickets. Strollers remain free to check even on budget carriers (this is essentially universal). For families on budget carriers, pack as much as possible into the free personal items and accept that checked bag fees are the cost of doing business.

Family Packing Strategies That Actually Work

Use Kids' Rolling Carry-Ons Strategically

Children's rolling carry-on bags are typically 18 inches tall or smaller — they fit in overhead bins easily and count as a carry-on for children who have paid for seats. Kids can generally manage pulling their own bag at age 4–5 and older.

The best approach: put your kids' clothes in your larger carry-on, and put their entertainment essentials in their own bag. This way kids carry what they actually care about (tablet, toys, snacks), and you control the clothing distribution to maximize packing efficiency.

A children's rolling carry-on can hold:

  • Tablet with case and headphones
  • Travel games and small activities
  • Snacks and a water bottle
  • A change of clothes (kept within reach for accidents)

Pack Fabrics That Earn Their Weight

For kids, fabric choice matters more than for adults because children change clothes more often and their clothes can be bulky relative to their size.

High-value fabrics for family travel:

  • Merino wool — naturally odor-resistant, can be worn multiple times before washing, works in hot and cold weather, dries fast
  • Quick-dry synthetics — T-shirts and shorts that dry overnight allow you to pack fewer items
  • Lightweight cotton blends — not as performance-oriented but easy to source replacements if needed

Invest in a few high-quality merino pieces for each child and you can genuinely cut the total number of clothing items in half for any trip over a week.

Pack Laundry Pods for Trips Over 5 Days

A small bag of laundry pods (3–5 pods) weighs almost nothing and allows you to wash clothes mid-trip at a laundromat, in a hotel sink, or using hotel laundry service. For trips over five days, this is usually more efficient than packing enough clothes to last the entire trip.

One load of laundry for a family of four mid-trip allows you to cut total packed clothing by 40–50%.

What to Gate Check vs. What to Bring On Board

Gate check (free, returned at jet bridge):

  • Collapsible strollers and umbrella strollers
  • Large stroller frames
  • Backpack carriers and hiking baby carriers
  • Oversized bags that don't fit overhead

Check at ticket counter (may have fees, picked up at baggage claim):

  • Hard-shell car seats (unless you're using the car seat on the plane)
  • Jogging strollers and large non-collapsible strollers
  • Large amounts of gear (camping equipment, sports gear)

Bring on the plane:

  • FAA-approved car seats if your child has their own seat
  • Diaper bag (usually counted as your personal item or allowed in addition)
  • Stroller that's small enough to fit in the overhead bin

The Car Seat Decision

Flying with a young child forces a decision about car seats: bring yours, buy one at the destination, or rent.

Gate check your own seat: Free, ensures you have the car seat you trust, but you must carry it through the airport. A car seat travel bag protects it and makes it easier to carry. Downside: car seats in the cargo hold can be damaged.

Use it on the plane: The safest option for children under 40 lb. FAA-approved car seats can be used in the aircraft seat (must be window seat). Your child must have a paid seat. This is recommended by both the FAA and pediatric safety organizations.

Buy or rent at the destination: Eliminates carrying a car seat entirely. Rental car companies offer car seats (quality varies, always inspect before using). Services like BabyQuip rent quality baby gear at destinations. For families who travel frequently, the cost of renting adds up — buying a dedicated lightweight travel car seat (like the Cosco Scenera) may make more economic sense.

Snacks, Formula, and Breast Milk Through Security

TSA policy gives families real flexibility on food and liquids for infants and young children:

  • Breast milk: allowed in reasonable quantities, exempt from the 3.4 oz rule. Declare at the checkpoint. May be tested by security.
  • Baby formula and juice: same exemption as breast milk. Reasonable quantities for the flight.
  • Solid baby food: generally allowed through security in reasonable quantities
  • Ice packs and gel packs: allowed to keep breast milk or formula cold, even partially frozen
  • Children's snacks: standard adult snack rules apply — no liquid restrictions on crackers, fruit pouches in small sizes, etc.

Leave extra time at security when traveling with infants and toddlers. Setting up the security bin, folding the stroller, removing shoes, and managing a child simultaneously takes longer than the average traveler allows.

Family Packing Checklist

Flight Entertainment Bag (Per Child)

  • Tablet or e-reader, fully charged
  • Child headphones (wired backup recommended)
  • Coloring books and crayons or markers
  • 1–2 small new toys (novelty helps on long flights)
  • Card games or travel games appropriate for age
  • Familiar comfort item (stuffed animal, blanket)
  • Downloaded movies, shows, and games

Diaper Bag Essentials for Flights

  • Diapers (1 per hour of travel time plus 4 extras)
  • Wipes (full pack)
  • 1–2 changes of clothes for the baby
  • 1 change of shirt for you (accidents happen)
  • Diaper cream
  • Changing pad
  • Hand sanitizer
  • Snacks appropriate for age
  • Formula or breast milk if applicable
  • Small toys and board books

Kids' Carry-On Must-Haves

  • Child's ID or passport if required
  • Child's boarding pass
  • Snacks (more than you think you need)
  • Water bottle (empty through security, fill at a fountain)
  • Headphones in a labeled case
  • Tablet or entertainment device
  • A favorite small toy or stuffed animal
  • Light jacket or layers (planes are often cold)
  • Change of clothes in a sealed bag

The Bottom Line for Families

Flying with kids doesn't have to cost a fortune in bag fees. Gate check your stroller for free, get a co-branded credit card that covers checked bag fees for your whole family, use kids' bags strategically, and pack merino and quick-dry fabrics to travel lighter. For longer trips, planning around laundry access beats packing two weeks of clothing for a family of four.

The families who travel most efficiently treat packing as a skill — and it's one that pays off every trip in saved fees, faster airport movement, and less stuff to manage with kids in tow.

Frequently asked questions

Do you have to pay to check a stroller on a plane?

No. Strollers are almost universally free to check on US airlines, regardless of your ticket type or fare class. You can check a stroller at the ticket counter along with your other luggage, or you can gate check it and receive it back at the jet bridge when you land. Gate checking a stroller is usually the most convenient option for families with young children.

Do children get the same baggage allowance as adults?

On most US airlines, children who have paid for a seat receive the same baggage allowance as adults — including the same carry-on and personal item allowance, and the same checked bag fees. Lap infants (children under 2 flying without a seat) typically do not receive a carry-on or checked bag allowance on domestic US flights, but are often allowed one collapsible stroller and one car seat for free.

What is the best stroller for air travel?

An umbrella stroller or lightweight compact stroller is the best choice for air travel. They fold quickly and small, fit in overhead bins on some aircraft, and are easy to gate check. Look for models that weigh under 15 lb and fold with one hand. For families with infants, a travel system that includes a car seat and stroller frame is practical, but the stroller frame can be gate checked while the car seat goes on the plane or is checked separately.

Can you bring breast milk and baby formula through airport security?

Yes. TSA allows breast milk, formula, and baby juice in quantities that are reasonable for the trip — these are exempt from the standard 3.4 oz liquid rule that applies to other beverages. You should declare these items at the security checkpoint. They may be subject to additional screening. Ice packs and gel packs used to keep breast milk cold are also allowed.

How can families save money on checked bag fees?

The most effective ways for families to save on bag fees are: get an airline co-branded credit card (many allow free bags for the primary cardholder plus travel companions), earn elite status on a preferred airline, choose Southwest which has traditionally included two free checked bags per person, pack carry-on-only when possible using kids' bags for their own belongings, or fly international airlines that include checked bags in economy fares.
