Frequently asked questions
Does this bag go free with Ryanair?
Yes. Since 2025, Ryanair has accepted a small 40 x 30 x 20 cm bag under the seat free of charge: this is exactly the size of this backpack.
What is the difference between model A and model B?
Both have the same format, shoe pocket, PC compartment and USB port; they stand out for their design. Compare them in the photos.
Can we fill it to the maximum?
Yes, as long as it keeps its 40 x 30 x 20 cm: avoid stuffing the exterior pockets, which count in the dimensions of the template.
Will the new European rules change anything?
In June 2026, the European Parliament and member states reached a provisional agreement: a personal item under the seat and a small cabin bag of 7 kg would be included in the standard fare. These rules will not apply until the end of 2027 at the earliest; until then, it's the dimensions in the table above that matter.
