Understanding the Aer Lingus Baggage Policy is essential for a stress-free journey. The airline offers specific allowances for carry-on and checked luggage based on your fare type and destination. Economy passengers typically get one cabin bag and a personal item, while Business Class travelers enjoy higher limits. Checked baggage weight and dimensions must follow airline rules to avoid extra charges. Aer Lingus also provides guidelines for sports gear, musical instruments, and oversized items. Familiarizing yourself with prohibited and restricted items helps prevent airport delays. Reviewing fees and allowances in advance ensures smarter packing, better planning, and smooth airport check-in with Aer Lingus.
