Understanding the Aer Lingus Baggage Policy ensures a smooth airport experience. All passengers are entitled to a carry-on bag and personal item. Checked baggage allowances depend on fare type, route, and booking. Economy fares typically don’t include checked baggage, while business fares do. Aer Lingus charges for excess weight or size, so it’s wise to weigh bags before traveling. Travelers can add baggage during booking or via the airline’s website. The Aer Lingus baggage policy also includes provisions for baby gear, sports equipment, and medical devices. Always review current baggage rules directly on Aer Lingus's website to avoid unexpected fees.
