We’ve written before here and here about flying with harnessed seats, but what to do if your kids are in booster seats?

Jen recently flew with her 6.5yo and 9yo, the first time without any harnessed seats, and here are some words of wisdom from a seasoned traveler.

Decide if a booster seat is a good choice for your child(ren) at your destination. Some factors to consider:

  • Is your child a practiced booster rider? A vacation is probably not the best time to start teaching your mature (usually 5.5-6+) 40+lb child how to sit properly at all times. Not when your not-so-wee one is tired, perhaps in a different time zone, or excited about the trip and unable to sit still. If a booster is on your radar for future travels start teaching your child well in advance so you have plenty of time to assess.
  • Will your destination involve long drives? Is your child likely to fall asleep in the car? If so then a booster might not be a good choice, especially if your child is still new to boosters.
  • How confident and practiced are you at assessing seat belt fit, and/or installing car seats? Is your vehicle at your destination a known entity, or is it a rental car? How flexible will you (and any traveling companions) be if the first rental car you are offered isn’t a good fit with your seats, and you need to unload everyone and start over?

I flew in December and chose to take a harnessed seat on the plane for my 6yo, and a booster for my 9yo. Although the 6yo is in a booster most of the time at home I knew that we’d have some long days of driving at our destination, and combined with the lack of sleep that goes with holiday traveling, she would not do well in a booster. My prediction was proven correct after a wicked meltdown and then a car nap on the first day, both very unlike her. Had she been in a booster seat we wouldn’t have been able to keep driving safely. Everything is hard when you’re tired.

This more recent trip didn’t involve nearly as much driving at our destination, and the flight was shorter and only through one time zone. I decided a high back booster would be suitable, and my partner is very used to me being rather picky with rental cars, so I knew my decision would be supported if I needed to switch to a different car at the airport.

For this trip I chose to bring a Harmony Youth Booster for the 9yo, and a Harmony Dreamtime Elite for the 6yo. These seats are both excellent choices for travel and everyday use because they provide consistently excellent seat belt fit, are lightweight, fit well in most cars, and are easy for my kids to use. Extra bonus, they are inexpensive. The regular price of the backless is about $20, and the high back is $55.

Unlike harnessed seats that can be installed on an aircraft seat, booster seats aren’t used on the aircraft. So bringing them takes a bit of planning.

There are two stages to my planning here:

  1. How will I get the seats to my destination undamaged?
  2. How will I make sure that my seats will wind up at the same place I’m going to?

The back of the Dreamtime Elite detaches from the base and fits easily into a large suitcase. I packed my clothes under, around, and on top of it. I’ll spare you the sight of my knickers and delicates, but you get the idea. It adds very little weight to the suitcase, and I was confident that any damage at our destination would be visible. It is always possible that my suitcase could go missing though, which is why part 2 is important.

Booster seats can’t be used in flight, but that doesn’t mean they can’t come into the cabin with us. I popped the boosters into cloth bags with handles that my kids could carry themselves…or let’s be honest, that I could carry after they got tired. Even laden down with other things I could still slide the bag’s handle onto my arm.

Once through security and on board the aircraft they fit easily into the overhead bins. Single seats also fit easily under the seat in front of me. I didn’t put them in the sizer but they aren’t big. Here are two stacked together with room to spare. My kids are big enough to fit comfortably into the airplane seats, and the seat belt can be properly tightened on them, which is also a factor when deciding on harness vs booster.

Ordinarily I wouldn’t want my 6yo in a backless booster. Since it’s impractical to carry the booster back onto the airplane (if it would even be permitted, which I doubt), I was comfortable packing it well into my suitcase and hoping it showed up. I had the booster bottom with me, so if needed, could have used that until the suitcase showed up.

And that’s it! We had a successful trip, and hope your future travels are smooth…bon voyage!


Some folks like to buy seats that are well-suited for travel. If you are considering a travel-specific/back-up seat purchase there are a few great options in all categories. This is not an exhaustive list and chances are good that the seat you own will work with some planning. The ones here are listed because they are narrow, lightweight, and inexpensive.

Rear-facing only (infant) seats – most install fairly easily without the base, and fit well on many airplane seats. Check your manual for instructions about aircraft installation.

Convertible seats – go to options include the Evenflo Titan 65/SureRide or Evenflo Sonus (for use rear facing and forward facing), and the Cosco Scenera NEXT rear facing. Both are lightweight, and compatible with the vast majority of vehicles. The Sonus sits low enough that the tray table can come down and be used by a forward-facing child.

Combination seats – Harmony Defender, Evenflo Maestro, and Graco Tranzitions are great options to start with.

Dedicated booster seats – remember that these can’t be used on the plane! But great options that are easy to swap between vehicles, and are lightweight and easy to transport include the Graco Turbobooster, Graco TakeAlong, Graco RightGuide, Graco Affix, Harmony Dreamtime, Harmony Youth Booster, Evenflo Amp, and Diono backless boosters.

Traveling with little ones can be stressful but with a little planning can go without major interruptions.  Living so far from my family is tough. The deal with my husband when we moved to Vancouver Island just over three years ago was that I could go home to see them in Ontario at least once a year.  When Thea was born in August I knew I would want to take her home to see my parents, siblings and extended family.  Being a child passenger safety advocate means I want my children protected on the airplane as well as in the car.  I waited patiently for a seat sale and bought us both seats.  Eight years ago I had traveled with my oldest daughter as a lap baby and not only was it frustrating but it didn’t seem right that I sat in my seat with a lap belt holding me in while baby was just free in my arms.  I’ve flown enough to know that turbulence and rough landings can sometimes happen, and have since learned about the risks of flying with a lap baby.

My decision to bring Thea’s infant seat on board was an easy one.  I have a large stroller I can pop my seat into but decided, per Air Canada’s preference for umbrella strollers, to just attach my infant seat to my lightweight travel stroller.  I used a long bungee cord and it fit snugly and perfectly.  I mostly baby-wear so I toted my carry-on in the stroller set up and put baby into the carrier.  I also printed out a copy of Air Canada’s car seat policy and made sure I chose a window seat for the car seat (see WestJet’s policy here).  You must not block the exit of passengers in an emergency so a window seat is required in this case.

We had two flights to make to get from Victoria to Toronto and the first was a small Dash 8 aircraft.  On all flights I was able to pre-board.  The infant seat buckled in securely and I had to move it quite close to the window as the belt was very short.  It only took a minute to get the seat ready to go.  Thea doesn’t particularly like being in her infant seat but she did really well and seemed to like the noisy engine of the Dash 8.  The flight attendant was helpful and offered to buckle the seat but I didn’t require her assistance.  The next flight from Vancouver to Toronto was uneventful too.  It was a 3-and-3 seat configuration.  The infant seat was next to Travel7the window and I was in the middle seat.  The seat belt stitching was a little thick and I had to tilt the seat to get it in the infant seat’s belt guides. I kept her in for take off and landing with a few walks about for nap time and diaper changes.  I was super happy to have her seat as the flight was pretty turbulent and holding her would have been a challenge.  It also afforded me some down time to watch a movie and eat when she slept.  But really, safety was my first concern.  I am not willing to check her seat and risk it being damaged or lost.

We used the seat baseless in my parents vehicle and it installed easily.  After a quick six day visit we were on our way back to Vancouver Island.  The flights back were also uneventful, and the flight staff easygoing and helpful.  I do not think I would have managed quite so easily if I had not purchased Thea her own seat.

We advocate for bringing restraints on board the air craft to best protect traveling children, other people on the plane (an unrestrained child could become a projectile), and the integrity and history of the restraint itself, as does Transport Canada, the US’s NTSB, and other child passenger safety advocates.  There are various options for how to fly with kids – read more here, or if your kids are older and in boosters, read more here.

Click here to read the Child Passenger Safety Association of Canada‘s position statement on the need for all passengers to be safely seated on flights.

Do you travel with more than one child? Are your kids in infant/child seats, or child/booster seats, or just boosters?  Some photos below to give you ideas of how to make it work even if you’re traveling as the only adult.

Some high back boosters will disassemble so the high back portion can be packed, well-padded, in a suitcase and checked; inspect it carefully for damage upon arrival.  A child old enough to be in a booster can very probably manage to carry their backless booster in a tote bag and stow it in the overhead bin on the plane. A booster can not be used on the aircraft as it requires a lap/shoulder belt, which of course a plane does not have.

Traveling solo? It can be done.  Car seat attached to rolling cart for smaller child, larger child (if large enough!) can sit directly on the plane seat with the belt. Rolling suit case, comfortable baby carrier…voila!  Car seat for older child was waiting at the destination.

So long as your luggage cart can handle the weight you can turn your car seat+cart combo into a stroller. Kids usually think this is a pretty spectacular way to ride.

Flying with your child?  Here’s how to deal with car seats, in order of preference:

1) Buy a ticket for your baby. A ticketed child, regardless of age, is allowed to use a car seat on board the air craft (nearly all seats for sale in Canada and bearing the National Safety Mark are certified for use on an air craft).  Safer for your child, safer for other passengers (your child won’t be a projectile), and safer for your car seat.  Use a rolling, folding luggage cart to roll through the airport.  Have more than one seat? Bungee them together! Click here to read the Child Passenger Safety Association of Canada‘s position statement on the need for all passengers to be safely seated on flights.

2) Arrange to have a seat at your destination, either borrowing from a trusted source or buying a new one (ordering online and shipping to your destination is a possibility).

***You still don’t want your child to be a projectile though. Consider using a CARES harness on board the aircraft, which restrains your child using the lap belt on the plane.  They’re for use with children between 22 lbs and 44 lbs, and up to 40″ tall, but please note there’s no crotch buckle so smaller kids can squirm out. After 40 lbs or so the plane’s lap belt is usually sufficient.  Click to see where to buy a CARES harness.  They cost around $100, and are lightweight and small, so can easily be stowed in a carry on bag for boarding.  Please, however, disregard CARES’ advice to ‘check your car seat and use a CARES harness instead.’

3) Box your car seat, in the original box if possible, and well-padded with pillows or clothes. Check it as special luggage.  It may be free if in the original box.

 

Much less desirable options from our perspective:

  • Gate check your car seat.  Walk it down the jet way, leave it at the door to the plane, and hope it’s there at your destination. No guarantees it won’t get battered in the hold, or it won’t accidentally get loaded onto the conveyors with the rest of the luggage. Inspect it carefully at your destination, removing the cover and looking for damage in any foam, plastic, or webbing.
  • Rent a car seat from a car rental place. You have NO IDEA how it’s been treated – dropped? – crashed? – harness washed or disinfected? – peed/pooped/vomited in? Is the manual there? Is it missing any parts?  Is it appropriate for your child or is your infant being given a booster seat?
  • Check your car seat as luggage. It’s free. Lot’s of people do it. It might get destroyed or lost though. Inspect it carefully at your destination, removing the cover and looking for damage in any foam, plastic, or webbing.

 

Watch the video below to see how car seats are treated when checked. Notice he’s just tossing the car seats on the runway. Car seats aren’t meant to be dropped, let alone tossed onto pavement.
