Popular Irish airline Aer Lingus has a hand luggage policy to ensure efficient and safe travel for its passengers. While you might be familiar with the basics, only a few understand certain Aer Lingus cabin bag size and weight policy guidelines.


What is the cabin bag size policy for Aer Lingus?

Aer Lingus has a complex hand luggage policy that differs depending on the flight type. When travelling trans-Atlantic, your cabin and personal items are included in your fare. However, if you’re flying in Europe, you’ll need to book a “Carry-on bag with priority boarding” ticket, starting at €9.99. Alternatively, you have the option to check your bag for free by placing it in the hold.

  • Regional flights: max. 48 x 33 x 20 cm (including handles, pockets, or other features) and up to 7 kg.
  • Other flights: max. 55 x 40 x 24 cm (including handles, pockets, or other features) and up to 10 kg.

You can also bring a small personal item that doesn’t exceed 25 x 33 x 20cm. The dimensions are in the Height x Width x Depth format. All carry-on luggage must fit in the overhead compartment or under the seat in front of you.

What is the carry-on liquid policy for Aer Lingus?

You are allowed to carry gels, shampoos, pastes, creams, and other liquids in a container that is not more than 100 ml. These containers should be packed in a clear, resealable bag with a maximum capacity of 1 litre.

You’re also allowed to bring the following liquids onboard Aer Lingus:

  • Medication supported by a doctor’s prescription statement.
  • Special dietary products like baby food.
  • Duty-free liquids. They should be kept in a sealed security bag.

What extra items can you bring on board

The following additional items are allowed on board Aer Lingus:

  • A collapsible stroller/pushchair plus a car seat, travel cot, or seat booster.
  • Medical equipment such as a foldable wheelchair or mobility aid.
  • Smaller musical instruments that meet the Aer Lingus hand luggage size requirements for regional or other flights. You can purchase an extra window seat if your instrument is larger than required. The weight of the instrument, including its case, shouldn’t exceed 75kg.
  • Urn carrying ashes. You should store it safely in a cushioned leakproof container not made of metal.

All hand luggage for infants (children below 2 years of age) must be included in the baggage allowance of the accompanying adult. It will be listed as a ‘Carry-on bag with priority boarding’; you cannot drop it off at check-in. You must take your cabin bags and personal items onboard. Children aged 2-12 have the same hand baggage allowance as adults.
