Aer Lingus Baggage Allowance: Cabin Bag, 10kg Bag and Checked Bags
From a few days away in Europe to a longer trip across the Atlantic, choosing the right luggage makes getting ready that little bit easier. If you are flying with Aer Lingus, start with your route and fare: these determine which bags are included and whether your 10kg case travels in the cabin or the hold.
Our guide takes you through the key allowances, with a few practical tips to help you find a case that suits your trip.
A 10kg bag must be no larger than 55 x 40 x 24cm. You can also take one small personal item up to 40 x 30 x 20cm. Check the allowance shown in your booking before you travel, especially if part of your journey is with a partner airline.
Cabin bag, personal item and Aer Lingus Regional
For Aer Lingus flights, the 10kg bag limit is 55 x 40 x 24cm, including wheels and handles. The bag must fit in the airport gauge.
On European journeys, a 10kg bag can be checked free of charge or taken into the cabin when it is included with your booking or you have added the 10kg carry-on option. A small personal item up to 40 x 30 x 20cm can travel with you too.
Aer Lingus has extended this 10kg policy to Regional flights. Always check your booking if you are connecting or travelling with another airline.
If you are travelling with just your small personal item in the cabin, keep your passport, medication and anything you will need during the flight in that bag. Your larger case may be checked into the hold, so it is worth separating these essentials before you reach the airport.
For a connecting journey, look at every flight on your itinerary. A case that fits Aer Lingus’ allowance may not fit another airline’s smaller cabin limit, even when both flights appear on the same booking.
Checked bags: choose the allowance you need
For flights within Europe, checked-bag options include 20kg, 25kg or two bags with a combined 40kg allowance. Saver fares usually need a bag added, while some higher fares include a 20kg checked bag.
For a longer trip, choose a case that suits the allowance you have booked rather than packing to the maximum before confirming it. Aer Lingus applies a maximum linear size of 158cm to one checked bag.

A medium suitcase can be a comfortable choice for a week away, while a larger case gives you more space for a longer stay or family packing. More space does not mean a higher weight allowance, though. Weigh your case after packing, and leave a little room for anything you plan to bring home.
Flying across the Atlantic? Check the checked-bag allowance shown against your fare rather than applying the European options above. It is also worth checking the operating airline where your itinerary includes a connection.
Find Your Aer Lingus Travel Companion
For a short break, a cabin case can help you keep things simple. Look for a model within the 55 x 40 x 24cm limit, including its wheels and handles, and check that taking your 10kg bag into the cabin is included or has been added to your booking.
For flights operated by Aer Lingus Regional, browse the Regional selection and compare the full outside dimensions with the allowance on your booking.
Think about how you will use your case beyond the flight, too. Easy-moving wheels are useful for the walk through the terminal, while separate compartments help you keep your outfits organised when you are living out of your suitcase for a few days.
Tripp recommendation: Our Aer Lingus cabin luggage selection is a good place to start for the 10kg allowance. If your trip calls for more space, explore our medium and large suitcases, choosing the size that suits your booked checked-bag allowance.
