Best Travel Diapers for Long Car Rides & Long Flights (Babies & Toddlers)

If you’re a parent who wants a diaper that can perform in “high stakes circumstances,” I have a few ideas to lend from my experience as a parent traveling with babies and toddlers.

A “travel diaper” doesn’t just mean a diaper that can hold a lot of liquid. It also means a diaper that’s going to prevent blowouts (no one wants a poop-covered shirt in the airplane cabin), help your child avoid diaper rash and provide comfort. A diaper is a really important part of a baby or toddler’s daily outfit on travel days!

In this list, I’ll tell you about the diapers I’ve tested and which you can TRUST, so that you pack your travel diaper bag or carry-on with the travel diapers that will not disappoint during your family trip. (At the bottom, don’t miss my FAQ, concerning all the questions I had about diapers the first time we left home with our baby.)

Best baby & toddler diapers for long flights and road trips

These are the travel day-approved diapers that can do a crucial trio of things: hold liquid to avoid leaks, prevent blowouts by having strong “sitting squish” factor and keep your child comfy with a good fit (no waistbands digging into their bellies during naps, night sleep or long hours in a car seat).

Oh, and if you’re new to flights with your little one, head to our guide on how to take a flight with a baby for the best tips, which comments quite a bit on the diaper topic.

Coterie

Coterie is my first pick for quite a few reasons, and you’ll see me packing Coterie diapers first every time I am readying my diaper fanny belt bag for a day spent on an airplane (or two).

I brought Coterie diapers with us on several trips, and originally this was because we got a great fit out of them (and I happen to think they’re super soft with the best stretch, too), but there are a few more reasons.

So because we got a great fit from Coterie, mainly because of the upper-back fit, and the elastic at the ruffles (the spot that contains messes, and after two babies, I feel that Coterie has one of the best designs at the legs), it’s our high-stakes performance diaper choice. Our 5.5-hour flight to Mexico City and our 6-hour flight from Bogota, Colombia, to NYC both went swimmingly with a child in diapers, thanks to real-world performance of the Coterie diaper.

Then of course, there’s a peace of mind that comes with having a good ‘road trip’ diaper that’ll keep a mess inside. We’ve been there, with the blowout that got all over a car seat, having to pull over to a picnic table in Upstate New York in the countryside. I don’t want to re-live it.

Coterie diapers are reliable for remaining absorbent, even during a flight when I may just put off changing one. And because of this solid choice in travel day diapers, I’ve never had to use that spare T-shirt I keep in my carry-on for unforeseen messes. I consider myself lucky.

And I don’t think there’s any parent out there who wouldn’t want to know that Coterie is officially EWG verified, meaning verified safe from 3900 chemicals and provides full transparency in ingredient disclosure. Only three diaper brands are EWG verified, currently, which is a big plus and a non-negotiable for lots of parents who travel.

Pampers Pure

There’s nothing wrong with a good ole Pampers diaper for travel days, especially because I find that the pack down pretty flat and slim for their absorbency capability.

I’ve flown with Pampers diapers, and packed a sleeve of them into my checked luggage, and I’ve used them on road trips up to Connecticut and New Hampshire, too.

Pampers Pure is a step up from the regular Pampers Swaddlers, and they have shea butter as an ingredient to help with skin-friendliness to babies.

They’ve had a good fit for our family, and the big selling point is the “Blowout Barrier,” which is a pocket at the back of them that serves as one more collection point for liquid messes rather than having them spew (gross, I know) out the backside of the diaper when a baby or toddler has been sitting for a while and pressing against their back.

So, overall these are a good choice, as well as “regular Pampers,” for the blowout barrier that a lot of parents think is a non-negotiable.

Kudos

Kudos is the first cotton-lined diaper (100% cotton in the inner liner) and for that reason, we find great absorbency with these diapers. I’ve used them for overnight, and for car rides.

What’s pretty good about them is that in our experience, they don’t even look so soppy or soggy when highly wet. That’s a plus, compared to some diapers that sag and look gigantic when they’re full of liquid after a few hours of urination.

The con is they do not have a blowout barrier, and the sizing can run really small, so I find that I have to actually get a size up from the size I’m using in a brand like Pampers.

Regardless, I’ve kept them in my travel day bag when we have them in the house, and my tip is that if you size up, they cover more of the back area. That’s how to avoid travel day blowouts mid-trip.

DYPER Charcoal Enhanced

We used Dyper Charcoal quite often for our first baby, and considered them as strong overnight diapers, or, as travel day diapers when we have everything to lose if a blowout were to mess up (quite literally) our day in transit.

Dyper Charcoal is a step up from the regular DYPER line, and they barely blow up when wet or full. They have a strong fit with high absorbency and like the original Dyper diaper, you could use one for 12 hours on an overnight flight and technically you could count on it for absorbing everything in that time period.

I have used these for all-day outings and times when I know it might be tough to find a changing table or changing spot (actually, this has been tough in a few parts of the world, namely South America).

Bambo Nature

I know what you’re thinking: Bambo? Yes, and I’ll tell you why. This is another diaper with a ‘tall’ fit (see the diapers below that I would NOT trust on a day squished in a car seat or sleeping on a flight).

They run tall, which, yes, I understand is not ideal for every baby’s body shape, but I still believe that having the back coverage is more crucial for out-the-back leaks. I say that becauseI have been there!

They’re also, like… how do I say this? For how thin they are, they have an impressive thinness-to-liquid-absorption rate. The first time I used these lesser-known diapers, I think I was shocked that they ‘actually’ do their job. So anyway, if you’re short on space in your luggage, my tip is that these diapers compress well, and they have a tall fit as well, so they have served as a travel day choice for me.

Diapers I will not use for travel days (and why)

These diapers don’t perform under high-stress (and squishing in car seats) on travel days. I’d say skip these.

Millie Moon

They just run so short and wide. The shortness matters because when a child is squashed and sliding or shifting in a car seat, you absolutely need the taller style diaper design to prevent back blowouts.

Pura

I’ve commended Pura as a sensitive skin diaper in the past, but the same reason sticks here as with Millie Moon, and the design is just too short and wide. They’re good for side coverage, but it’s the back blowout that’ll spoil your travel day.

Luvs

Luvs is known as the most economical diaper (one I’d send to daycare and buy in the bulk box of 144!) and with the rock-bottom price, the quality gets compromised. They’re papery, plasticky and thin, so I wouldn’t count on a Luvs diaper to hold in messes during a flight or road trip.

Cuties (Kirkland)

Kirkland (Costco) diapers now use Cuties as their supplier and these diapers are just too thin and papery. Even if parents claim they hold in things like poop and pee when squished in car seats, I don’t trust the absorbency in high-pressure scenarios like full-day car rides and road trips.

Why a travel diaper matters

I am someone who actually DOES pack an extra T-shirt in our travel diaper bag (this was my cousin’s tip, and I referenced it in our guide of how to fly with multiple kids!). Luckily I have not had to use it while flying with a baby, due to diaper blowouts!

A travel diaper matters because basically you want to rid yourself of the worry and anxiety of “will this diaper hold everything if my child falls asleep on my lap for 3 hours on the flight,” or, “Will this diaper hold in an unexpected mess, in our kid’s car seat, because a soiled car seat would be a nightmare.”

So, what am I looking for in a travel day diaper for babies and toddlers?

• Must be extremely absorbent for no leaks
• Must also have great wetness absorption so that a child doesn’t feel wet and squishy
• Fit: must go high in the back, to keep messes inside rather than coming up the back in a car seat
• Must have strong elastic coverage at the ruffle (this is what keeps messes in, rather than leaking out)

So while these are the real-world reliability must-have’s for me, you might even have a few more! When it comes to choosing a diaper brand for your long-haul travel days, I suggest going with a brand you can trust, if you’re having concerns about leaks and blowouts.

Frequently asked questions about travel day diaper choices

I had SO many questions about diapers the first time I flew with our 8 month old. I was losing my mind. Here are a few questions and my answers to them.

Should I bring an overnight diaper on the plane?

You could, especially if you plan to fly red-eye, or during a stretch of night sleep. Overnight diapers are indeed more absorbent and can hold more liquid than a regular daytime diaper.

One good thing about Coterie diapers is that the brand doesn’t make daytime vs. nighttime diapers: all Coterie diapers perform and can hold enough liquid to count as an overnight level of diaper quality.

What if I don’t plan to change a diaper during the flight?

You still might have to. I was so petrified of changing a diaper on an airplane (how do you even do it, I wondered?) that I wrote this airplane diaper change how-to guide for first-time parents!

Even if you know your baby’s “schedule,” surprises happen, especially at altitude with the new pressures of flying thousands of feet up in the air.

While toddlers are more predictable than babies, I’d say, there’s always the risk of new foods causing bellyaches, medicines causing side effects, and more. You might just have to change, so reference your list of toddler diaper bag essentials for travel, in a list like this one.

How many diapers do I bring on the plane for my baby?

Some children fuss when their diapers or wet (or if they have a #2), so you know your baby best; however, I still recommend having a diaper for every 2 hours of flight time. Then, add a diaper for a change right before you board, and a diaper for when you land, in case there are surprises at baggage claim, customs or passport control at your destination.

How often should I change my baby during a road trip?

Use the logic from any other time you’re with your baby: change your baby if there is a funky smell, or if they are fussy, which might be from a poop. If you stop at a rest area, I recommend always changing your baby, and they typically have 1-2 changing tables in the restrooms.

Of course, if your baby is taking a long car nap, do not wake them to change them if they’re sleeping peacefully, but DO go by your car seat’s safety guidelines of how long a baby should spend strapped in before having a full-body stretch or break from it.

I suggest using my guide on what to pack on a road trip with a baby if you’re having doubts or blanking on necessities.
