Underseater luggage 40x30x20: compact, spacious and always with you
An underseater is the cabin bag you can take on board as your personal item. The 40x30x20 cm size is compact enough to meet the baggage rules of many European airlines, while still giving you the space you need for a short trip. At Frenky, the idea is simple: less hassle, more packing space. Browse the collection and find the underseater that suits your travel style.
-
The 40x30x20 size is a smart choice for air travel. It fits within the personal item rules of many European low-cost airlines. That means less chance of extra baggage charges, no need to check in a suitcase and no waiting at the baggage carousel.
For weekend trips, city breaks and business flights, this size is ideal. You have enough room for clothes for two to four days, a laptop or tablet, toiletries and your travel essentials.
Thanks to Frenky’s vacuum function, you can pack smarter than you think. The compression system makes your clothes flatter, so you can fit more into your bag without increasing its size.
-
The difference between a regular compact bag and a Frenky underseater is the vacuum function. Clothes that normally take up a lot of room can be compressed, creating extra space for the things you would otherwise leave at home.
The result is a 40x30x20 cm bag that feels much roomier than expected. You travel compact, but you do not have to compromise as much on what you bring.
-
Yes, as long as you choose the right bag. The 40x30x20 cm size is commonly used as a guideline for personal items that fit under the seat. In practice, the exact space can vary depending on the airline and aircraft type.
Frenky bags are not only compact in size, but also designed with flexible materials. This makes them easier to slide under the seat, even when space is limited.
Tip: avoid overpacking your bag. A slightly flexible underseater is easier to fit under the seat and gives you less stress at the gate.

Flights with strict baggage rules
Airlines such as Ryanair, Wizz Air and other low-cost carriers often charge extra for larger cabin bags. A 40x30x20 underseater helps you travel without unnecessary baggage costs.
-
Frenky offers underseaters in two practical styles: backpacks and trolleys. Both are designed around the 40x30x20 size and both include the vacuum function.
A 40x30x20 backpack is easy to carry on your back, which is useful if you walk a lot or want to keep your hands free. A cabin trolley is easy to roll through the airport, especially across long terminals and smooth airport floors. Both are smart choices. The best option depends on how you like to travel.

All Frenky underseaters are designed to respect the baggage rules of many airlines while giving you as much packing space as possible. Compact on the outside, surprisingly spacious on the inside.
