Why does Ryanair check cabin bags so often?
amin bram
Ryanair checks carry-on bags very often because its baggage policy is one of the strictest in Europe. Its low-cost model relies on low headline fares, offset by frequent surcharges, particularly on luggage.
Every extra centimeter or kilogram becomes a source of revenue… but also a rigid control point. Agents visually measure (or use a sizer for) almost every bag, especially during priority boarding.

FAQ on Ryanair's strict carry-on bag policy
Why does Ryanair impose such a small free size?
Because a smaller size ensures faster boarding and encourages paying for a larger bag (10 kg carry-on or checked).
Do they check every passenger?
Not always. But if your carry-on bag looks full, rigid, or visually oversized, you are very likely to be checked.
Is the check based on weight or dimensions?
Both can be checked. The most common is a sizer test. If it doesn't fit, you are charged several hundred euros in fees.
Does a 40×30×20 bag always pass?
Yes, if it is soft and well-packed. Our models are calibrated exactly for this format, with practical pockets and a very low empty weight.
