Underseat luggage FAQs, answered:
What counts as underseat luggage?
Also called a personal item, underseat luggage is any piece of hand luggage that fits underneath the aeroplane seat in front of you. While it was originally just a bag or purse used to store smaller items like a book or tablet you might want to use during the flight, nowadays people are maxing out the requirements by picking underseat cabin bags that fit everything required for a short trip.
What are the size requirements for underseat luggage?
Annoyingly, it can vary depending on your airline. There are no specific underseat requirements for airlines like British Airways and TUI, who include stowing a cabin case or bag in the aeroplane’s overhead locker as part of their standard economy tickets.
Ryanair, easyJet, or Wizz Air require any bag you bring to fit seamlessly underneath the seat in front of you if you want to avoid additional luggage costs.

Can an underseat bag replace a carry-on suitcase?
“For many travellers the answer is yes, but it depends on how you travel,” says Kirsty Glenne, CEO of Antler House of Brands. “If you’re travelling for a weekend or even a few days with a carefully planned wardrobe, an underseat bag can absolutely replace a traditional carry-on suitcase.”
She continues: “I think the key to travelling with an underseat bag is in the packing. Choosing versatile clothing, limiting footwear and making the most of internal compartments enables you to pack more efficiently than many people expect. Using packing cubes can also help maximise space while keeping everything neatly organised.”
What features should you look for in underseat luggage?
“One of the first things to consider is the size of your bag,” adds Kirsty. “As dimensions differ between airlines, choosing one designed to fit beneath most aircraft seats can make travelling much less stressful.
“Look for practical features that make life easier, such as organised pockets for your headphones, water bottle and other essentials. Bags with padded shoulder straps, sturdy grab handles and a luggage sleeve are all worth having too, as they make travelling much more comfortable.
“Durability is another key factor to consider. Hard-wearing materials, quality zips and strong construction will help your bag cope with regular travel, whether you’re flying or commuting.
“Finally, choose a bag you’ll use beyond the airport. The Icon Overnight Bag and Heritage Overnight Bag are great examples of bags that work just as well for weekends away, commuting and everyday use!”
What is the best material for an underseat bag?
“There isn’t a single ‘best’ material for an underseat bag,” shares Kirsty. “The right choice depends on how you travel, but durability, weight and how easy the bag is to maintain should always be top priorities. A well-made underseat bag should be able to withstand frequent lifting, sliding under airline seats and everyday wear, while remaining lightweight enough to carry comfortably. Unlike more rigid materials, soft fabrics can adapt more easily to the limited space beneath an airplane seat, making it easier to maximise your packing without exceeding airline size restrictions.”
How do I maximise space in an underseat bag?
“My top tip would be to choose clothing that can be mixed and matched, and keep shoes to a minimum, as they’re often the bulkiest items in your bag. Packing cubes are a great way to stay organised, save space and make it easier to find what you need — especially compression zips.
“Rolling clothes instead of folding them can help reduce creases and make better use of every inch. Pack heavier items at the bottom of your bag, fill any gaps with softer clothing and keep essentials like chargers, toiletries and travel documents in easy-to-reach pockets.”

How I test the best underseat luggage:
For this round-up, I requested multiple pieces of underseat luggage — including laptop backpacks, weekend bags and carry-on suitcases — from various brands to see which delivered in terms of support and style.
After using each multiple times, I reviewed each against the following criteria:
| Materials & durability | Is the underseat luggage of good quality, hard-wearing and fit for purpose? What is the quality of the zippers, stitching, handles and wheels like? |
| Dimensions & airline compatibility | What are the actual external dimensions, including the wheels and handles? Does it fall within common underseat limits? Does it expand to accommodate bulky or additional items? |
| Capacity & organization | How does the usable interior space compare to the advertised litres? How many compartments are there, and how practical are they? Does it have a laptop or tablet sleeve? Are there easy-access pockets for your phone, wallet and passport? |
| Weight | What is the empty weight, and does it comply with airline regulations? |
| Wheels & manoeuvrability | Does it have two or four wheels? Are they of good quality and smooth? Do the wheel housings reduce the interior space? What is its stability like when standing upright? |
For those I haven’t yet had proper travel experience with, I called on my colleagues and trusted contributors for their recommendations. I also sifted through customer reviews to get the lowdown on each model, and used sites like Mumsnet and Reddit for extra opinions.
Only the pieces of underseat luggage that impressed all around made it into this edit — and sadly, the following didn’t make the cut. Read more about how we test here, and in terms of what I’m currently testing, stay tuned for these reviews:
Why you can trust me:
Despite starting my journalism career on the showbiz desk of a national newspaper, I pivoted to shopping three years ago and have since penned product reviews for UK titles like Glamour, GQ, Condé Nast Traveller, Cosmopolitan and Women’s Health. During that time, I’ve reviewed fashion essentials like underwear, shapewear and activewear, the latest wellness launches and lifestyle buys, such as best-selling luggage and underseat bags.
In terms of my working week, it’s a mix of personal testing, writing up my findings and attending press events to catch up with brands or experts — activewear designers, women’s health experts and brand founders — to gain answers to common FAQs.
In terms of my personal experience with luggage, I don’t travel light and so rarely rely on underseat luggage alone. However, ahead of writing this round-up, I challenged myself to travel across Europe without putting a suitcase in the hold. I can confirm I successfully managed to pack light for trips to Florence and Edinburgh, ahead of the Fringe Festival, plus for a long off-grid weekend with Unplugged.
