Aer Lingus Baggage Policy: Carry-On & Checked Rules
Aer Lingus quietly updated its carry-on policy in early 2026, raising the weight limit on regional flights from 7 kg to 10 kg — a change that affects a significant chunk of routes across Ireland, the UK, and Europe. Whether you’re traveling on a Saver fare or have splurged on Flex, here’s everything you actually need to know before you pack.
Carry-on Allowance: 1 x 10kg bag + 1 small personal item ·
Free Checked Bag: 20kg per customer on non-Saver fares ·
Personal Item Examples: handbag, laptop bag, baby changing bag ·

What is the free baggage allowance on Aer Lingus?
Aer Lingus includes checked baggage differently depending on which fare you book. Smart and Flex tickets on European routes come with one free checked bag up to 20 kg, while Saver fares make you pay extra for anything that won’t fit under the seat. MyBaggage breaks down the specifics: the same 158 cm linear limit applies across all fare types, but weight distribution is where the cost difference kicks in.
Carry-on details
Every Aer Lingus passenger can bring one piece of hand luggage up to 10 kg and one small personal item such as a handbag or laptop bag onboard. The main carry-on bag maxes out at 55 × 40 × 24 cm, while personal items are limited to 25 × 33 × 20 cm. Larger carry-ons go in the overhead lockers; smaller items fit under the seat in front of you.
Checked bag inclusion by fare
- Saver (European and Transatlantic): 0 kg checked — hand baggage only unless you pay
- Smart and Flex (European): 1 × 20 kg checked bag included free
- Smart and Flex (Transatlantic): 1 × 23 kg checked bag included free
- Plus, Advantage, and AerSpace: first checked bag (M – 20 kg) at no cost
The implication: if you’re flying Saver and need checked luggage, book early — fees climb the closer you get to departure. Near Saver baggage during booking runs €25 for 20 kg, while Far Saver reaches €55 for the same allowance.
Aer Lingus charges €10 per extra kilo on European excess baggage. A bag that tips 21 kg costs you €10 at the counter before you even board.
What is the new 10kg carry-on baggage policy on Aer Lingus?
Effective March 3, 2026, Aer Lingus bumped the regional carry-on limit from 7 kg to 10 kg — bringing turboprop routes in line with mainline jets for the first time. Aer Lingus Media Centre confirms the policy covers domestic Ireland and UK flights, cross-border Ireland-UK routes, and European services operated by Emerald Airlines.
Size and weight limits
- Weight: 10 kg maximum
- Dimensions: 55 cm height × 40 cm width × 24 cm depth
- Personal item: up to 25 × 33 × 20 cm, must fit under the seat
- Maximum single piece weight: 32 kg (checked bags only)
Personal item allowance
The personal item slot covers handbags, laptop bags, and baby changing bags. One small personal item per passenger is included free on all Aer Lingus and Aer Lingus Regional flights. Aer Lingus Official notes that adding a carry-on bag online costs from €9.99 if your fare doesn’t already include it.
Saver passengers on regional flights can check their 10kg bag into the hold for free but pay €9.99 to keep it in the cabin — the opposite of the usual gate-checking penalty.
What are the new rules for carry-on luggage in 2026?
The headline 2026 change is straightforward: Aer Lingus Regional flights (fleet number range EI 3000 – EI 3999, operated by Emerald Airlines) now match mainline carry-on allowances. Irish Times reports that every fare type already includes a 10 kg bag as standard — the difference is whether you can carry it on or must check it.
Enforcement changes
Gate agents check both weight and dimensions at boarding. Bags that exceed 55 × 40 × 24 cm or tip the scales past 10 kg get tagged for hold storage and count toward your checked allowance — with additional charges if you’ve already maxed that out. The strictness varies by airport, but VisaHQ notes this is part of a broader push to standardise cabin baggage across the Aer Lingus network.
The pattern: Aer Lingus has gradually eliminated weight tiering between regional and mainline flights, creating a single 10 kg standard that applies whether you’re flying a turboprop across Ireland or a jet to continental Europe.
Regional variations
- Pre-March 3, 2026 Regional: 7 kg max, 48 × 33 × 20 cm
- Post-March 3, 2026 Regional: 10 kg max, 55 × 40 × 24 cm (matches mainline)
- Transatlantic routes: Smart and Flex include 1 × 23 kg checked bag
Can I bring a backpack and a carry-on on Aer Lingus?
A backpack counts as your main carry-on piece if it meets the 10 kg and 55 × 40 × 24 cm limits — it doesn’t get a special exemption just because it’s soft-sided. MyBaggage clarifies that all Aer Lingus passengers are permitted one piece of hand luggage and one small item onboard.
Backpack as carry-on or personal item
- If your backpack fits the 55 × 40 × 24 cm frame and stays under 10 kg: it acts as your primary carry-on
- If it’s smaller and lighter (25 × 33 × 20 cm, soft): it could qualify as your personal item instead
- Two large backpacks won’t both fit in the overhead — one goes in the hold if it exceeds limits
Size restrictions
The practical reality: travel packs and school-style backpacks often fall within the carry-on dimensions but push the weight limit once packed with clothes and a laptop. Weigh your bag at home before departure — gate agents at busier airports like Dublin and Heathrow tend to check more consistently.
Aer Lingus does not publish a hard list of approved bag types. If you’re unsure whether your backpack qualifies as carry-on or personal item, err on the side of the smaller dimension limit and check the weight at home.
Does Aer Lingus give you a free checked bag?
Aer Lingus includes a free checked bag on most fare types — but Saver fares are the exception. MyBaggage specifies that European Saver passengers receive zero kilograms of checked allowance, meaning only hand luggage unless they pay.
Fare types
- Saver (European): 0 kg checked — pay per kilo for any hold bag
- Saver (Transatlantic): 0 kg checked — no complimentary hold baggage
- Smart and Flex (European): 1 × 20 kg free checked bag
- Smart and Flex (Transatlantic): 1 × 23 kg free checked bag
- Plus, Advantage, AerSpace: 1 × 20 kg free checked bag
The implication: Saver passengers on transatlantic routes have no free hold option at all. Either upgrade your fare or pack everything into your carry-on — but watch that 10 kg cap.
International and transatlantic
Transatlantic Smart and Flex fares offer a slightly higher weight allowance (23 kg) compared to European routes (20 kg), reflecting the longer flight duration and typical passenger needs. Excess transatlantic baggage costs €75 per bag — notably steeper than the €10 per kilo charged within Europe.
Aer Lingus charges €75 per bag for transatlantic excess baggage versus €10/kg within Europe — a gap that makes pre-planning essential for Saver fare passengers.
The breakdown below shows how Aer Lingus baggage allowances vary across fare types and routes.
| Fare Type | Route | Carry-On | Personal Item | Checked Bag | Excess Fee |
|---|---|---|---|---|---|
| Saver | European | 10 kg (€9.99 to board) | 25 × 33 × 20 cm | 0 kg (pay per kilo) | €10/kg |
| Smart/Flex | European | 10 kg | 25 × 33 × 20 cm | 1 × 20 kg free | €10/kg |
| Saver | Transatlantic | 10 kg (€9.99 to board) | 25 × 33 × 20 cm | 0 kg | €75/bag |
| Smart/Flex | Transatlantic | 10 kg | 25 × 33 × 20 cm | 1 × 23 kg free | €75/bag |
| Plus/Advantage | Regional (EI 3000–3999) | 10 kg (free) | 25 × 33 × 20 cm | Varies by booking | Varies |
Upsides
- Free 20–23 kg checked bag on Smart, Flex, Plus, and Advantage fares
- Standard 10 kg carry-on now applies across regional and mainline routes
- Saver passengers can check a 10 kg bag into the hold at no charge
- AerClub Silver, Platinum, and Concierge members receive free 10 kg carry-on on regional flights
Downsides
- Saver fares offer zero complimentary checked baggage
- Carry-on fee of €9.99 for Saver passengers who want the bag in the cabin
- Transatlantic excess baggage costs €75 per bag — significantly higher than Europe
- Gate enforcement on dimensions varies and can catch unpacked travellers off guard
