Search & Book
These fares are the result of a sale that ends on January 31, 2025. You can find the available dates on Google Flights or the airline’s landing page. There seems to be quite good availability to most destinations between February and August 2025. You should book these flights directly on Aer Lingus’ website.
Why is booking with an airline better than with an online travel agency?
More often than not, online travel agencies offer lower fares than airlines do. We still recommend booking with the airlines directly. There are two main reasons for that:
Better Customer Service
In case any problems like delays, cancellations or missed connections arise, you can communicate directly with the airline. The airline has to take care of you because you have a contract with them.
If a travel agency issues your ticket, you may have to reach out to them first. You also depend on your OTA to forward information like flight changes instead of receiving them directly from the airline. In many cases, you may get a prime exhibition of responsibility shifting rather than problem-solving.
This especially applies to premium tickets. You don’t want to spend more than €1,000 to wind up with some budget OTA’s telephone hotline in case anything goes wrong.
Baggage and Other Fees
Economy fares not including hold luggage are industry standard by now. In most cases, travel agencies charge much higher baggage fees than the airlines themselves. If bags are not included in your fare, airlines are often the cheaper alternative.
This also applies to other things like food services, insurances or priority treatment. In almost all cases, you pay less for additional amenities when booking on the airlines’ website.
Miles & Points
Aer Lingus issues these tickets in booking class A. A roundtrip between Brussels and Dublin earns you:
- 1,000 Miles on Alaska Mileage Plan
- 250 Avios + 38 Tier Points on The British Airways Club
- 244 Award Miles on United MileagePlus
- 138 Avios + 15 Tier Credits on Aer Lingus AerClub

It’s not 10kg checked allowance, it’s a Carry-on Baggage that you either must check in or pay 9.99€ extra to take it on board! Hence the strict dimensions.
Plus, if you bring it to the gate without having purchased “Carry-on bag with priority boarding” or checked it in, you will pay 35€ fee.
I suggest you look at https://www.aerlingus.com/prepare/bags/carry-on-baggage/ to get the full story and don’t end up paying extra.
