Aer Lingus expands free 10kg carry-on to all regional flights starting March 3, 2026, for most fare types.

Aer Lingus will expand its 10kg carry-on baggage allowance to all Aer Lingus Regional flights starting March 3, 2026, including routes from Southampton to Dublin and Belfast. The policy, effective for Plus, Advantage, and AerSpace fare holders, allows one free 10kg carry-on bag meeting size limits (55cm x 40cm x 24cm), plus a small personal item. Silver, Platinum, and Concierge members also receive the benefit on UK and European flights. Saver fare passengers may check their bag for free or pay to carry on. The change, driven by customer feedback, aims to improve convenience for business and leisure travelers.
