Ryanair announced it will increase the size allowance for free cabin baggage within the coming weeks, aligning with new European Union regulations aimed at standardizing cabin bag rules across airlines. The airline plans to expand the dimensions of the free carry-on bag, increasing the under-seat bag size from 40x25x20 centimeters to 40x30x20 centimeters, representing a 20% increase in size. This change comes ahead of the summer holiday season and follows agreements among EU airlines to harmonize luggage policies. The EU is also working on new rules that would set a minimum free bag size for all carriers and allow passengers the option to carry an additional free bag weighing up to 7 kilograms. Travel expert Simon Calder confirmed the new personal bag size on BBC Breakfast, highlighting the regulatory push for passenger convenience. Ryanair's decision follows recent EU moves to establish standardized cabin baggage dimensions, aiming to reduce confusion and improve passenger experience.
