Aer Lingus carry-on size and weight in 2026
Aer Lingus (Ireland, IATA code EI) allows cabin bags up to 55 cm long, 40 cm wide and 24 cm deep; the weight limit is 10 kg.
The dimensions include wheels, handles and outer pockets. A soft bag can usually be squeezed a little, but a hard-shell suitcase cannot lose that extra centimetre — and that is exactly when gate staff ask you to pay.
Instead of guessing, open Kalibrator: pick Aer Lingus, enter the size of your suitcase or bag and see in 3D whether it fits the sizer and where exactly it sticks out.
