Kono Ryanair 40x20x25 Under The Seat Holdall Cabin Hand Luggage Travel Bag, 20L (Grey/Brown)

A compact under-seat holdall built around Ryanair-style sizing

If you’re trying to keep your cabin luggage to a tight, under-seat friendly footprint, a holdall like this Kono Ryanair 40x20x25 bag is designed to do one job well: fit the “maximum sized” approach many people need for budget flights. On paper, it’s aimed at the sort of cabin hand luggage rules that prioritise small bags you can place beneath the seat rather than fighting for overhead space.

It comes as a 40x20x25cm under-seat flight bag with a stated capacity of 20L. The weight is listed as 0.45kg, which matters if you tend to pack light anyway. The overall feel you’re meant to get is straightforward travel organisation: quick-access pockets for the things you reach for during the flight, and a couple of options for carrying depending on what else you’re dragging through the airport.

That said, it’s still a soft holdall, so it’s not going to behave like a rigid suitcase when you’re trying to keep your packing perfectly structured. If you like your bag to stand up on its own and stay crisp, you may find a structured bag more satisfying.

What you’ll notice in use (and why the layout matters)

This bag is set up around practical, in-flight access. There’s a large main compartment for your core items, plus an internal zip pocket described as a space for a passport. For smaller essentials, it includes two inner slot pockets for a mobile and changes (so, phone and loose money/coins).

For anything you want to grab without unpacking, there’s also a front quick access pocket intended for travel documents and other items. In real travel terms, that can be the difference between doing a full rummage for your boarding pass and just opening one front section.

It’s also got four protective feet on the bottom. Those are small details, but they can help the bag sit more stably when you’re using it at your seat, and they’re there to support day-to-day durability.

A micro-example: on a flight, you could keep headphones and a snack in the front quick access pocket, your passport in the internal zip pocket, and your phone in one of the inner slot pockets—then only open the sections you need while you’re waiting to board.

Carry options: hand, shoulder, or over a trolley

The design offers three ways to carry it, which is useful because airport movements aren’t always consistent. There are two top handles with a velcro clasp for hand carry. There’s also a length-adjustable shoulder strap if you’d rather keep your hands free.

If you’re travelling with a larger cabin suitcase, the rear of the bag includes a dedicated mounting sleeve. The idea is that you can slide it over the extendable trolley handle, rather than stacking it awkwardly on top of everything else. It’s a simple feature, but it tends to be the kind you end up using every time once you have it.

Materials and build: what’s stated, and what to be cautious about

The bag is described as being made from oxford cloth, with gun colour hardware. Based on the information provided, that points to a fabric that’s intended for frequent travel rather than a stiff, premium-feeling shell.

Because it’s a holdall (soft-sided), it’s sensible to keep expectations realistic: it should work for organised packing and under-seat placement, but it won’t give you the same “protect your contents with hard walls” approach you’d get from a more rigid case. If your packing includes items that you really want shielded from pressure, you may need to rely on your internal packing (pouches, clothing wrap, or a small organiser) to make up for the softness.

Also, while the description claims broad airline acceptance, airline rules can change and can be interpreted differently depending on route and aircraft. So it’s worth treating the sizing guidance as a helpful fit approach, not a guaranteed permission slip.

Airline compatibility claims: useful context, but double-check your route

The listing states that it is designed around Ryanair’s “new main hand luggage allowance”, and says it’s accepted on virtually all major airlines worldwide, including easyJet, British Airways, Etihad, Emirates, Delta, Flybe, Lufthansa, Norwegian, Jet2, KLM, Quatar, Wizz Air and Virgin Atlantic.

That’s helpful for shoppers comparing whether an under-seat bag will travel well across different carriers. However, it’s still a good idea to check your specific airline’s current cabin baggage rules before you fly—especially if you’ve booked a ticket with strict allowance conditions. Budget airlines in particular can be tight on measurements and how bags are positioned.

If you’re someone who regularly switches between airlines, this kind of all-rounder “max sized holdall” concept can be handy. If you only ever fly one airline and you want absolute certainty, you’ll still want to verify the dimensions match the current policy for your booking.

Pros

• Designed around a specific under-seat cabin size: 40x20x25cm.
• Lightweight for what it is (0.45kg listed).
• Practical internal layout: passport zip pocket plus phone/changes slots.
• Quick access front pocket for documents and flight essentials.

What may not suit everyone

• Soft-sided holdall, so it’s not the best choice if you need rigid protection for delicate items.
• Broad airline acceptance is claimed, but baggage rules can still vary in practice—so don’t assume it replaces checking your allowance.
• If you’re expecting a lot of structure, you may find it more “bag-like” than “case-like” once packed.

Should you buy it?

It makes sense if you want a compact under-seat cabin bag sized at 40x20x25cm, with an organised interior for travel documents, your phone, and flight-day essentials, and you prefer being able to carry it by hand or on your shoulder (or clip it over a trolley when you’re using a larger suitcase).

You may want to skip it if your priority is rigid protection for contents, or if you’re planning to pack bulky items that need a firmer shell and a more structured shape. It also depends a lot on your airline’s current baggage interpretation—so if you can’t be bothered to double-check the rules for your exact flight, that’s a point in favour of choosing an alternative where you can be more confident about compliance.
