Aer Lingus baggage allowance policy allows you to bring one small cabin bag and one personal item, without incurring the extra charges. The baggage allowances are subject to certain terms & conditions. If your carry-on baggage size exceeds the maximum limit, you will be responsible for additional costs. You may purchase the extra luggage when you make a reservation with Aer Lingus.
