Like me, you’ve probably found that searching for the best travel car seat is one of those things that sounds simple until you actually try to do it. Finding a car seat that’s approved for the plane while they are still small enough to sit in one, light enough to carry through an airport, compatible with hire cars you don’t see until you get there, and ideally suitable for more than six months before your baby outgrows it. It’s a lot to ask of one product and in our experience, no single seat ticks every box.
We’ve been travelling with R since he was just a couple of months old (he’s now nearly 17 months), and we’ve worked through the full journey from newborn infant carrier to foldable toddler seat. Here’s what we have finally settled on using, broken down by stage.
Can you take a car seat on a plane?
Yes (providing it’s cabin approved), and if you’re hiring a car at your destination, bringing your own travel car seat is always the better option when it comes to cost. Hire company seats vary wildly in quality, cleanliness, and suitability for your child’s age and size. Taking your own means you know exactly what you’re getting.
But we also had reservations about checking our car seat into the luggage hold of a plane. I’d seen how some airports chuck baggage onto baggage carousels or into trucks – was it risky putting an item that needs to be in impeccable order into that environment?
For the first 15 months, we decided to book R a seat on all UK and European flights, bringing our car seat on board. And for US trips which require different, US-approved car seats anyway, we took the hit on costs and hired when we got there.
There are two things to check before assuming your seat is good to go though:
1. The aircraft approval sticker
Your car seat needs to carry specific aircraft approval, not just a European road safety standard. For UK and EU seats, look for a TÜV sticker confirming it’s certified for use on a plane. The ECE R44/04 or R129 label covers road use but doesn’t automatically mean it’s approved for aircraft. Check the label, and take the instruction booklet with you in case airline staff ask for it at the gate.
Which? has a clear breakdown of the rules and how different airlines handle car seats – worth reading before your first flight.
2. Whether you can use your UK car seat in the US
This catches a lot of British families out, as UK and European car seats are certified to ECE R44 or R129 standards, but US hire car companies operate under a different standard (FMVSS 213) and may refuse to let you use a European-certified seat in their vehicle. It’s worth checking directly with your rental company before you travel. We’ve used BabyQuip for US trips – they deliver inspected, clean baby gear including car seats direct to your hotel or rental property, or even offer airport drop off.
For Europe, you’re fine, as UK seats approved to ECE R44.04 or UN R129 are valid across all EU countries.
The best travel car seat for under 15 months: Maxi-Cosi Pebble
We used the Maxi-Cosi Pebble for R from birth, and it came on a lot of flights with us. It’s one of the most widely used infant carriers in the UK for good reason: it works with most travel system pushchairs (see our travel pram recommendations), the seatbelt install means you don’t need your ISOFIX base abroad, and several versions carry TÜV aircraft approval.
Both the Pebble and the Pebble 360 Pro² have the same height limit of 87cm, which in practice means most babies outgrow them around 15 months – exactly when R did (but he’s a little on the tall side). Maxi-Cosi quote up to 18 months for the Pro², but that’s their estimate for an average-sized baby and the 87cm limit is the hard ceiling either way.
Pebble vs Pebble 360 Pro²: which one?
The Pebble 360 Pro² is the newer version and is what we’ve used in our home car since R was born (and what we’ve always taken on the aircraft with us until recently). The headline upgrade is 360° rotation plus SlideTech, a seat that slides out towards you as it rotates, which makes getting a baby in and out much easier – although of course this doesn’t matter when travelling as you won’t have the base. It also has a full lie-flat position in all modes, which is handy, but both versions are TÜV aircraft approved and both install with just a seatbelt.
If you’re packing for your first trip with a baby, our baby holiday packing list covers everything from carry-on essentials to hold luggage, and our guide to flying with a baby shares the tips we’ve learned from doing it many times over.
What we use at home: the Maxi-Cosi Pearl Pro²
For day-to-day use now we’ve outgrown our Pearl, the Maxi-Cosi Pearl Pro² is great and a seat we love. It runs from around 6 months up to 4 years (67–105cm), stays rear-facing throughout, and sits onto the rotating ISOFIX base.
But since the Pearl is ISOFIX-only, it stays at home – there’s no seatbelt install option, so it’s not the right call for hire cars or taxis abroad.
The best travel car seat for 15 months and beyond
Once your baby outgrows the infant carrier stage, finding the right travel car seat gets trickier. Full-size toddler seats are heavy and bulky, and most require heavy bases. The ultra slick travel ones are front-facing and can feel a little questionable for a young toddler.
After much research, this is what we use:
For hire car trips: the Graco SlimFit R129
For trips where we have a hire car for the week, we use the Graco SlimFit R129. It’s a 2-in-1 convertible that stays rear-facing from birth up to 105cm (around four years), then converts to a forward-facing highback booster all the way to 145cm (around 12 years). For travel purposes, the key selling points are that it installs with the car’s seatbelt which means no ISOFIX is needed and it works in any hire car. I love that it stays rear-facing for as long as you want it to, which is what we wanted. The longevity is also really useful – this seat will cover R for years, not just one holiday stage.
The trade-off with any seatbelt-installed seat in a hire car is that you lose the rotating base you might have at home. In a hire car it’s seatbelt only, so you’re installing the traditional way. Still safe, just not quite as convenient.
We book hire cars through Auto Europe for European trips. Just don’t count on the rental company’s own seat being up to scratch – take your own wherever you can.
For transfers and taxis: the Maxi-Cosi Nomad Plus
For trips where we only need a car seat for airport transfers or the odd taxi, we own the Maxi-Cosi Nomad Plus. It weighs 4.26kg, folds completely flat into its own carry bag, and installs with the car’s seatbelt in around 30 seconds. It fits any car, which is exactly what you need when you don’t know what the driver is going to turn up in.
It’s designed for 15 months to four years. If you’re looking for a foldable travel car seat for a one or two year old specifically, this is the one to look at – when folded it’s barely bigger than a large handbag, and for a 20-minute airport transfer it’s pretty ingenious.
The trade-off is it’s forward-facing only. I’m not entirely comfortable with it for daily drives or a road trip holiday given R is only 16 months, so we keep it for short hops – but plenty of parents rave about it.
If you want a second opinion before buying, the Car Seat Safety UK Facebook group is worth joining – it has nearly 100k members and a range of experts who answer questions and check installations via photos.
What about the Nomad XL?
The Maxi-Cosi Nomad XL Plus is a step up. The key differences:
- Age range: 15 months to 12 years (vs 15 months to 4 years on the Plus)
- Installation: ISOFIX and top tether in harness mode, then seatbelt in booster mode (vs seatbelt only on the Plus)
- Weight: 6.2kg (vs 4.26kg on the Plus)
- Converts to a booster: yes, at 100cm height
- Both are forward-facing only
The XL makes more sense if you want one seat that covers the toddler years and beyond, or if your car has ISOFIX and you want to use it. For pure travel portability, the Plus is lighter and more compact.
The best car seat travel bag for holidays
This felt like a minor detail until we had to stop putting the car seat on top of our pram and check it alongside a cot, several suitcases and carry it with a toddler in one arm and our on-board bag in another.
We use this backpack-style car seat travel bag and it was £80 very well spent. It has protected the seat in the hold well so far (important given a car seat that takes a heavy drop should technically be replaced even with no visible damage), and the padded backpack straps mean you can carry it hands-free through security. It’s solid and well-made, not flimsy – although I’d still suggest putting some clothing around the car seat for extra precautions. I’ve added it to my baby travel packing list as a must-buy if you’re putting the car seat in the hold.
