Flying with Ireland’s flag carrier and unsure what you can bring onboard? The Aer Lingus baggage policy is driven by your fare type, not just your route — which is where most travellers get caught out at the gate. This guide breaks down the full Aer Lingus baggage allowance for 2026, covering carry-on rules, checked bag limits, fees, sports equipment, infant allowances, and AerClub perks, so you can pack smart and avoid surprise charges.
How the Aer Lingus Baggage Policy Works
Aer Lingus structures its baggage allowance around three things: your fare brand (Saver, Plus, Advantage, AerSpace or Business), your route (European short-haul vs. transatlantic long-haul), and your AerClub loyalty tier. Aer Lingus’ baggage allowance is primarily determined by the destination and the specific fare brand, such as Saver, Plus, or Business. Additionally, AerClub elite status also influences the permitted weight and dimensions of a passenger’s baggage.
Understanding this fare-driven system is the key to the entire Aer Lingus luggage policy. A Saver fare behaves almost like a budget ticket, while Plus and Business fares bundle in checked bags and overhead access.
Aer Lingus Carry-On Baggage Allowance
Every passenger on every fare gets one small personal item free of charge. The carry-on bag (cabin bag), however, depends on your fare.
The Aer Lingus cabin bag size limit is 55 x 40 x 24 cm (21.5 x 15.5 x 9.5 in) with a maximum weight of 10 kg (22 lbs). You can also bring one small personal item, e.g. small handbag, laptop, duty free or baby changing bag with a maximum size: Height: 40cm (15.5″) Width: 30cm (11.5″) Depth: 20cm (8″).
Here’s the catch most guides bury: All customers are allowed to travel with a 10kg bag and a small personal item. There are two options for your 10kg bag: a 10kg bag can be brought on board the aircraft only if you have purchased a “10kg Carry-on bag” or have this included as part of your booking. This is included for Silver, Platinum and Concierge AerClub members, bookings made with Plus, Advantage or Aer Space fare types, Economy fares purchased via British Airways, and the accompanying adult travelling with an infant.
If you hold a Saver fare and want overhead bin space, Saver fare passengers wanting overhead bin space must purchase carry-on access separately, typically costing €9.99–€35 depending on route and booking timing.
Aer Lingus Regional (Emerald Airlines) Carry-On
On Aer Lingus Regional flights the rules tighten. For Aer Lingus Regional flights (operated by Emerald Airlines), you can bring one piece of cabin baggage up to 7 kg with maximum dimensions of 48 x 33 x 20 cm. Exceed that and you will be charged a €35/£35 fee to place this bag in the hold.
Aer Lingus Checked Baggage Allowance
Checked baggage is where fare type matters most. For Saver fares the checked allowance is nil — it must be purchased. For Economy Smart/Flex fares it’s 1 bag of up to 50lb/23kg. For Business/Business Flex fares it’s 3 bags of up to 50lb/23kg each.
Size and weight caps apply to every checked bag: the size of a checked bag must not exceed 158cm (62in) in combined dimensions and the weight must not exceed 70lb/32kg.
For European routes, Saver passengers buy weight in tiers. For the Saver fare, baggage can be purchased at a cost of approximately €50 per flight. If you have a return ticket, you must purchase the luggage together for both the outbound and return journey. A money-saving tip: purchasing bags online is up to 50% cheaper than purchasing at the airport. You can book your bags at discounted rates online up to 2 hours before your flight’s departure.
Pooling Your Baggage Allowance
Travelling as a group? Passengers travelling on the same booking and checking in together are allowed to pool their baggage allowance. This is handy when one bag is overweight and another has room to spare.
Aer Lingus Baggage Fees & Excess Charges
Excess and gate fees add up fast. The official rate is clear: excess baggage is charged €10 per kilo. Importantly, customers are not permitted to upgrade a bag to a higher weight at the airport on the day of departure — excess fees will be applied to any weight over a customer’s personal allowance.
The gate fee is the one that stings most. If your carry-on bag exceeds the size or weight limits at the gate, you will be required to check it. A gate baggage fee, which is higher than pre-booking online, may apply. On European flights, this fee is typically around €35. The same applies to Saver passengers who arrive with an overhead bag they didn’t pre-pay for.
Often the smarter move is upgrading your fare entirely. Sometimes the cost of upgrading from a Saver fare to a Plus or Smart fare is less than the cost of adding a checked bag separately. This often includes other benefits like seat selection.
Sports Equipment & Musical Instruments
Travelling with skis, golf clubs or a guitar? These count as special items requiring advance booking. Sporting equipment can be checked into the aircraft’s hold, limited to one per person and must not exceed 23kg in weight. Within Europe, sporting equipment can be carried for approximately €40 per item each way. On long-haul routes, on transatlantic routes, sports equipment can sometimes count as your standard checked bag.
For instruments, musical instruments can be carried by hand as cabin baggage if within the size and weight limits. Larger items can be checked into the hold, as per sporting equipment.
Infant & Child Baggage Allowance
Families get useful free extras. For infants (children below 2 years), the allowance is 22lb/10kg plus 1 fully collapsible stroller/buggy plus a travel cot/booster seat/car seat. On transatlantic routes, infants get 1 x 10 kg checked bag included free, in addition to the adult’s allowance, while on European routes there’s no separate checked baggage allowance for infants.
AerClub Loyalty Baggage Benefits
Elite status pays off here. Silver, Platinum, and Concierge members flying on European routes get one free 20kg bag. On transatlantic flights, Silver members can check one 23kg bag for free, while Platinum and Concierge members can check two or three, respectively.
Packing Safety Rules
A few non-negotiables before you zip up: spare lithium batteries, power banks and e-cigarettes must travel in your carry-on, while sharp objects belong in checked baggage. Liquids in cabin bags are limited to 100ml containers — though if you’re departing from Dublin, a 2-litre allowance applies per customer.
Final Tip: Check Your Fare Before You Pack
The single most important rule of the Aer Lingus baggage policy is to read your fare type carefully before you book — not at the gate. Run the maths on Saver-plus-baggage versus a Plus fare, pre-pay any bags online to save up to 50%, and confirm whether your flight is operated by Emerald Airlines so the tighter 7kg regional limits don’t catch you out.
