Outsmart the Overhead Locker Charge with an Underseat Cabin Bag
An underseat cabin bag is one of the cleverest travel investments you can make, especially if you fly regularly with budget airlines. Sized to slip under the seat in front of you rather than into the overhead locker, these bags qualify as a free personal item allowance on many low-cost carriers, meaning you can board without paying a penny extra for luggage. Here's everything you need to know about choosing the right underseat luggage for your travels.
What Is an Underseat Cabin Bag?
An underseat cabin bag, sometimes called a personal item or under-seat bag, is a compact travel bag designed specifically to fit within the free baggage allowance offered by most airlines. Rather than going in the overhead locker, it slides under the seat in front of you during the flight, keeping your essentials close to hand throughout the journey. The range includes carry bags, sport bags, 3-way boarding bags, and business tote bags, all built to meet the compact dimensions airlines specify for free personal items, without skimping on usability or style.
This category sits within the broader world of cabin luggage, but with a key difference: while a standard cabin suitcase typically requires a paid baggage upgrade on budget carriers, a correctly sized underseat bag often flies completely free.
Understanding the Size: 45x36x20 and 40x30x20 Underseat Cabin Bags
If you've been searching for a 45x36x20 underseat cabin bag or a 40x30x20 underseat cabin bag, you're already thinking like a seasoned traveller, because those two sets of dimensions are the key to flying for free with Europe's biggest budget airlines. Here's what they mean in practice:
- 45x36x20cm (easyJet): This is easyJet's maximum free personal item size. A 45x36x20 underseat cabin bag is slightly larger than the Ryanair and Wizz Air equivalent, giving you a little more packing room while still qualifying as a free carry-on. Always measure your bag externally, fully packed, before heading to the airport.
- 40x30x20cm (Ryanair & Wizz Air): The more compact of the two allowances, this dimension applies to both Ryanair and Wizz Air's free personal item policies. A small underseat cabin bag within these measurements boards free on both carriers, making it the most universally useful size if you fly across multiple budget airlines.
Individual products in this range carry clear on-page labels indicating which airlines have confirmed them as compliant. Always treat these as a helpful guide rather than a guarantee, dimensions must include any structural elements, and airline staff measure bags at their discretion. Policies can and do change, so always verify directly with your airline before you fly.
Underseat Cabin Bag with Wheels. The Best of Both Worlds
One of the things that makes this range genuinely stand out is that it includes underseat cabin bags with wheels, a rare combination that gives you the effortless rolling of a wheeled case alongside the compact dimensions needed to qualify as a free personal item on budget airlines. If you've ever searched for a 45x36x20 underseat cabin bag with wheels that actually fits within easyJet's free allowance, or a 40x30x20 underseat cabin bag with wheels for Ryanair and Wizz Air travel, this is the range to explore.
For travellers who find carried or shoulder-worn bags uncomfortable over longer distances through the airport, a wheeled underseat cabin bag is the ideal solution, compact enough to slide under the seat in front of you, but with smooth-rolling wheels that take the strain out of getting there. Check individual product pages to confirm exact dimensions and airline compliance before travelling, as policies can vary and are subject to change.
What Styles of Underseat Bags Are Available?
The underseat luggage range covers a variety of bag styles to suit different travellers and different types of trips. Rather than a one-size-fits-all approach, you'll find options designed around specific needs:
- Carry bags and travel bags: Versatile, shoulder-worn or hand-carried underseat bags that are easy to manage through the airport and slide neatly under the seat once on board. Many styles include a dedicated laptop compartment for up to 15.6" laptops, making them ideal for business travellers or anyone who needs their tech within reach during the flight.
- Sport underseat bags: A more active take on the underseat format, with practical organisation and a streamlined profile that works just as well exploring your destination as it does in the terminal.
- 3-way boarding bags: These clever hybrid bags can be carried in multiple ways, typically as a shoulder bag, a handheld bag, or worn across the body, giving you maximum flexibility on the same trip. A great all-rounder for travellers who want one underseat cabin bag that adapts to every situation.
- Business tote bags: A polished option for professional travellers, combining generous carry capacity with a sleek, boardroom-ready look. Perfect if you're heading straight from the airport to a meeting.

Can a Small Underseat Cabin Bag Replace a Full Carry-On?
For short trips, city breaks, overnight stays, or quick business trips, absolutely. A well-packed small underseat cabin bag can comfortably carry a change of clothes, toiletries, your tech essentials, and everything you need for a day or two away. The key is packing smart: roll clothes rather than fold them, use small pouches to keep toiletries organised, and prioritise versatile items that work across multiple occasions. For longer trips where you need more than underseat luggage can hold, pairing it with a larger hardside cabin suitcase or lightweight cabin luggage gives you a complete carry-on setup that maximises your total allowance.
Underseat Bags vs Standard Cabin Luggage. What's the Difference?
The main distinction comes down to size and where the bag is stored during the flight. A standard cabin suitcase, typically around 55cm, goes in the overhead locker and generally requires a paid cabin bag allowance on budget airlines. Underseat luggage is significantly smaller, designed to sit under the seat in front of you, and qualifies as a free personal item on many low-cost carriers. If you're flying with a budget airline and want to avoid paying for a cabin bag upgrade, an underseat cabin bag is the smarter choice. If you need more packing space and your ticket includes a cabin bag allowance, a full-size cabin luggage option is the way to go – and you can always bring both.

FAQ
Is an underseat bag really free to take on budget airlines?
Yes, provided your underseat cabin bag falls within your airline's stated free personal item dimensions and you're travelling on a standard ticket that includes a personal item allowance. Most major budget airlines, including Ryanair, easyJet, and Wizz Air, allow one small personal item per passenger at no extra charge, as long as it meets their size restrictions. This is one of the key advantages of choosing underseat luggage over a larger cabin suitcase, which typically requires a paid upgrade on budget carriers.
Can I carry a laptop in my underseat cabin bag?
Many of the underseat bags in this range include a dedicated laptop compartment designed to fit laptops up to 15.6 inches, making them a practical choice for business travellers or anyone who travels with a computer. Having your laptop in your underseat cabin bag rather than in checked luggage gives you easy access during the flight and ensures it stays safely at your feet rather than in a hold. If you plan to travel with a laptop in your underseat bag, make sure the bag, fully packed, laptop included, still fits within your airline's free personal item dimensions. A packed bag can sit differently to an empty one, so it's worth doing a test run before your travel day to avoid any last-minute surprises at the gate.
Can I bring both an underseat bag and a cabin suitcase on board?
This depends entirely on your airline and the ticket type you've purchased. On full-service airlines, passengers are often permitted both a personal item and a larger cabin bag as standard. On budget airlines like Ryanair, easyJet, and Wizz Air, a free personal item is included with most tickets, but a larger cabin suitcase for the overhead locker typically requires a paid upgrade. If you've purchased a ticket tier that includes a cabin bag allowance, you can often bring both an underseat bag and a full-size carry-on. Combining underseat luggage with a paid cabin bag allowance is one of the most effective ways to maximise your total luggage capacity without paying for checked baggage, just make sure to check exactly what your specific ticket includes before you pack.
What's the difference between an underseat bag and a personal item?
They're essentially the same thing, just described using different terminology. Airlines often refer to the smaller free bag allowance as a "personal item," while travellers and luggage brands tend to call the bags designed for this purpose "underseat bags," "underseat luggage," or "underseaters." Both terms describe a compact bag that fits under the seat in front of you during the flight, within the airline's stated free dimensions. Some airlines use slightly different language in their policies, "personal item," "small bag," or "under-seat bag", but the concept is consistent: a bag small enough to stow at your feet, included free with most standard tickets.
