How to Pick a Kids Travel Backpack for Flights
Trunki BoostApak leads this list, since it folds into a certified car booster seat and an 8 liter carry-on shell. Families wanting more room should pick the Wildkin 17-Inch Kids Backpack, which holds folders and a lunch bag at a lower price. Travelers pulling luggage through terminals do better with the Rockland Rolling Backpack.
Trunki BoostApak wins for flights requiring a car booster seat, folding one 8 liter shell into both roles, though it holds little beyond the booster itself. Wildkin’s 17-Inch Kids Backpack covers school and travel duty at a lower price, but skips wheels entirely. Rockland’s Double Handle Rolling Backpack helps tired legs across long airport concourses, adding bulk on stairs in return.
Sizing a kids backpack is harder than sizing an adult one, since shoulder width, torso length and airline rules all shift with age. A bag built for a toddler crushes under school folders by age nine, and an oversized pack throws off a preschooler’s balance. We compared listed dimensions, capacity and age recommendations, wheeled versus strap-only designs, and fabric ratings for daily use, then weighed owner reports on zipper wear, washability and flight performance.
Our top picks
Trunki BoostApak Ride-On Kids Suitcase and Backpack
This backpack unfolds into a car booster seat, then collapses back into an 8 liter carry-on shell for the return flight. A hard plastic interior survives a booster’s daily bumps, and a padded cover keeps contact points comfortable. Fold-out seatbelt guides hold the lap strap steady on car and rideshare rides, fitting children in the 126 to 150 cm range most booster laws require.
Pros
- Converts into an ECE R129 certified booster seat
- Compact 8 liter shell meets most carry-on limits
- Removable cover wipes clean or machine washes
Cons
- Holds little beyond the booster itself at 8 liters
- Hard shell weighs more than soft-sided packs
Wildkin 17-Inch Kids Backpack
Three zippered compartments keep folders, a lunch bag and loose supplies separate instead of one crowded pouch. 600 denier polyester shrugs off bus floors and airport carousels better than lighter nylon. Side pockets on each side fit a water bottle, useful during layovers, while a moisture resistant lining guards books against spills.
Pros
- Three compartments keep travel gear organized
- 600 denier fabric outlasts lighter nylon packs
- Side pockets hold water bottles for flights
Cons
- No wheels, so kids carry the full weight
- Print options vary by retailer and sell out fast
High Sierra Mini Fatboy Backpack
A scaled down 16 liter body fits elementary aged kids better than adult sized daypacks with straps that slide off. Its core organizer pocket keeps pencils and small toys away from books. A mesh side pocket holds a bottle without opening the main compartment, and the empty pack weighs just 0.6 pounds.
Pros
- Lightweight shell adds almost no weight at 0.6 pounds
- Core organizer pocket sorts small items from books
- Compact size clears carry-on limits for most airlines
Cons
- 16 liters runs tight for overnight trips
- Straps carry less padding than larger packs
Rockland Double Handle 17-Inch Rolling Backpack
A telescoping handle and double skate wheels let kids pull this bag instead of carrying it through long terminals. Its 13 x 10 x 17 inch frame stands upright alone, thanks to a reinforced plastic base. Two front pockets, one with a built-in organizer, separate small items from clothing, and backpack straps tuck away while rolling, then unclip for stairs or gravel.
Pros
- Wheels spare small shoulders on long concourses
- Reinforced base lets it stand upright at gate checks
- Straps convert it for stairs when wheels won’t work
Cons
- Wheels and handle add bulk versus soft packs
- Telescoping handle can loosen under heavy daily use
JanSport Big Student Backpack
Two large main compartments hold textbooks, a change of clothes and trip supplies across 34 liters, more room than most kids’ branded packs. Recycled 600 denier polyester shrugs off daily drops at school pickup. An internal sleeve secures laptops up to 15.5 by 12.5 inches, and S-curved shoulder straps spread weight better than flat straps on smaller frames.
Pros
- 34 liter capacity suits multi-day trips
- Recycled polyester holds up to daily school use
- Laptop sleeve fits most school issued devices
Cons
- Sized more for tweens than younger kids
- No wheels for kids who prefer rolling luggage
Fenrici Backpack and Lunch Box Set
A matching 17 inch backpack and insulated lunch box keep meals separate from clothes and toys on travel days. That lunch box measures 10.8 by 8.5 by 2.8 inches, sized for a sandwich, snacks and a cold pack. 900 denier polyester resists tearing at zipper stress points, while dinosaur, shark and galaxy prints give younger kids a bag they actually want to carry.
Pros
- Matching lunch box keeps food separate from gear
- 900 denier fabric resists tears near the zippers
- Print designs appeal to younger boys and girls
Cons
- Lunch box needs a separate cold pack
- Fewer compartments than the Wildkin backpack alone
Skip Hop Spark Style Big Kid Backpack
A 14 inch tall body suits kids over 48 inches, smaller than most school backpacks on this list. Its wide top opening lets little hands load and unload without adult help. A clear front zip pocket holds small toys where a preschooler can see them at security checks, and easy clean, phthalate free material wipes down after snack spills on the plane.
Pros
- Wide opening suits kids packing their own bag
- Phthalate free fabric wipes clean after spills
- Sized right for preschool through early elementary
Cons
- Too small once kids pass the 48 inch mark
- Fewer compartments than school-focused packs

How to pick the right one
Matching Backpack Size to Age and Height Torso length matters more than the age printed on a label. A pack too large throws off balance on jet bridges and stairs, while an undersized one crushes school folders. Skip Hop’s Spark Style fits kids over 48 inches tall, while the JanSport Big Student suits taller tweens carrying laptops. Check listed dimensions against your child’s current backpack before buying, since brands size differently even at the same stated age.
Does a Kids Backpack Need to Meet Carry-On Rules? Most airlines cap personal item or carry-on backpacks near 45 linear inches, and every pack here falls under that limit. Trunki’s BoostApak, at 40 by 36 by 16 cm, was built around carry-on sizing from the start. Larger 34 liter packs like the JanSport Big Student still clear overhead bins on most US carriers, though gate agents can size check bags on full flights. Confirm limits with the specific airline before departure, since budget carriers run tighter than legacy ones.
Wheeled Backpack or Straps for Family Trips Wheels help on long airport concourses but add bulk on stairs, cobblestones or crowded train platforms. Rockland’s Double Handle Rolling Backpack converts between rolling and backpack straps, useful for mixed itineraries. Strap only packs like the Wildkin 17-Inch stay lighter and stow easier under a plane seat. Families flying through large hub airports lean toward wheels, while those doing city trips with stairs often prefer straps.
Durability and Organization for Repeat Travel Daily school use and travel both punish zippers, straps and base fabric, so denier count matters more than it sounds. 600 and 900 denier polyester, used in the Wildkin and Fenrici packs, resists tears better than lighter 300 denier nylon. Moisture resistant or wipeable linings matter too, since spilled juice on a flight is a matter of when, not if. Multiple compartments, rather than one large pouch, keep snacks separate from electronics on multi-day trips.
Questions worth asking
What size backpack is best for a 5 year old traveling?
Look for packs under about 14 inches tall with a shorter strap drop, similar to the Skip Hop Spark Style or Trunki BoostApak. Oversized adult style packs throw off balance at this age. Check the brand’s listed height range rather than relying on age alone.
Can kids travel backpacks fit in an airplane overhead bin?
Packs under about 45 linear inches, including every model here, fit standard overhead bins or under the seat ahead. Budget carriers sometimes enforce tighter personal item sizing, so check the airline’s own chart. Trunki’s BoostApak was sized specifically for carry-on limits at 40 by 36 by 16 cm.
Is a rolling backpack better than a standard backpack for kids?
Rolling packs like the Rockland Double Handle help on long airport walks, since small legs tire faster than adults’. Standard straps stay easier to manage on stairs, cobblestones or crowded trains. Families mixing both trip types often prefer a convertible design that does both.
How many liters should a children’s travel backpack hold?
Day trips and flights work fine with 8 to 16 liters, covering snacks, a toy and a light jacket. Overnight or multi-day trips need 25 liters or more, closer to the JanSport Big Student’s 34 liter capacity. Match capacity to trip length instead of buying the largest bag available.
Are kids travel backpacks machine washable?
Soft fabric packs like the Wildkin and Fenrici models generally tolerate gentle machine washing per their care labels. Trunki’s BoostApak relies on a removable padded cover that washes separately from the plastic base. Check the specific listing’s care instructions before washing, since linings and prints vary.
What age is a toddler backpack no longer appropriate for flights?
Toddler sized packs like the Skip Hop Spark Style fit kids over 48 inches tall, roughly preschool through early elementary. Beyond that height, straps sit too high and the body feels cramped for school supplies. A 17 inch pack like the Wildkin or Fenrici suits the next size stage.
Kids travel backpack vs children’s travel backpack, is there a difference?
Both terms describe the same product category, used interchangeably across most listings. Search results and Amazon categories mix both terms depending on the brand’s own labeling. Focus on listed dimensions, age range and capacity rather than the exact wording used.
Can a kids carry-on backpack double as a school backpack?
Packs with multiple compartments and durable fabric, like the Wildkin 17-Inch or JanSport Big Student, handle both school and travel use well. Toddler focused packs, such as the Skip Hop Spark Style, work better for short trips than daily hauling once a child outgrows the sizing. Choosing a dual purpose pack avoids buying separate travel and school bags.
Which kids backpack works best for a family with a booster seat requirement?
Trunki’s BoostApak solves that need directly, folding into an ECE R129 certified booster seat between flights. It trades general capacity for that dual function, holding little beyond the booster itself. Families without a booster requirement get more everyday room from the Wildkin or JanSport packs.
The bottom line
Trunki BoostApak is the strongest overall pick for families flying with a car booster seat requirement, solving two travel problems in one 8 liter shell. Parents packing for a full week should choose the JanSport Big Student instead, for its 34 liter capacity and laptop sleeve. Families walking long airport concourses with a tired preschooler in tow are better served by the Rockland Double Handle Rolling Backpack.
