The Aer Lingus baggage policy is designed to provide flexibility while ensuring compliance with weight and size restrictions. Passengers are allowed one cabin bag up to 10 kg and one small personal item, with size limits strictly enforced. Checked baggage allowances depend on the fare type—Saver fares do not include checked bags, while Plus, Advantage, and Business fares offer one or more checked bags with weight limits ranging from 20 kg to 32 kg. For overweight or additional luggage, fees apply and vary by route. Familiarizing yourself with the Aer Lingus baggage policy before departure helps avoid extra charges and ensures a smooth boarding process.
