Popular Irish airline Aer Lingus has specific carry-on baggage policies to ensure efficient and safe travel for its passengers. While you might be familiar with the basics, it’s worth familiarizing yourself with the updated Aer Lingus carry-on size and weight policy guidelines.
Aer Lingus carry-on size policies explained
According to their luggage guidelines, Aer Lingus allows each traveler to bring 1 small personal item such as a purse, laptop bag, small handbag, or briefcase on all flights. Carry-on luggage is included free of charge on transatlantic and regional flights, but not on European flights.
The Aer Lingus carry-on bag size will differ depending on the type of flight:
All carry-on luggage must fit in the overhead compartment or under the seat in front of you.
The Aer Lingus carry-on weight limit will also depend on your flight type. The combined weight of your carry-on bag and small personal item shouldn’t exceed 7kg (15lb) on regional flights. If you opt to bring a carry-on onto a European or transatlantic flight, it should not weigh more than 10kg (22lb), but your personal item doesn’t factor into that.
If you’re having problems fitting everything, check out this handy guide to packing your carry-on.
Note that Aer Lingus has updated its carry-on policy for European flights. If you want to bring a carry-on bag of up to 10kg, you must add it for a fee of €9.99/£9.99, unless you have priority status. Depending on your ticket, you may, however, check this bag free of charge.
