Aer Lingus Promo Codes - August 2025

Getting an Aer Lingus promo code is not impossible, but they are extremely rare. Savoo has tracked Aer Lingus deals since 2011, and only a few genuine promo codes have appeared since then.

That said, you can still save on Aer Lingus flights in other ways:

• Look out for holiday package deals as they sometimes include £100+ discounts.
• Sign up for the Aer Lingus newsletter for early access to offers.
• Follow Aer Lingus on social media to learn about flash sales and limited-time fares.

Despite a lack of codes, our users save £161.66 on average when booking flights. We will update the Aer Lingus page on Savoo as soon as a discount code becomes available for the travel company.

No they don’t. You can book online, via mobile or at the airport at no added charge. You can check in online or on mobile within 48 hours of your scheduled departure time on all routes within Europe and within 24 hours of your scheduled departure time on all routes to and from North America.

If your baggage weighs over the allowance, you will be charged extra. The baggage allowance will depend on your fare. Visit the Aer Lingus site to see the baggage limit and charges on your destination.

For children under 2 years old, a 10kg/22lb checked baggage allowance is included as part of the booking. For children aged 2-12, the checked baggage allowance is the same as for adults and will depend on the fare.

You will be allocated a seat at check in but if you have a special preference for where you would like to sit, pre-book your seat in advance of your flight. Be warned though, pre-booking a particular seat comes with an additional fee that starts at just £3.99.

Aer Lingus doesn't offer a student discount on fare bookings. Their official site also doesn't list any student-specific promotions, but that's not the end of the story.

Student-targeted platforms like StudentUniverse can often help you save money. One Reddit user claimed they grabbed almost €200 off using a StudentUniverse Aer Lingus fare, although we cannot substantiate this.

Alternatively, Aer Lingus always has a collection of active promotions and low prices available.

Flights to and from the United States may be cancelled and fully refunded within 24 hours of booking, provided booking is made at least 7 days in advance of departure. Any other cancellations must be made up to two hours before the scheduled departure time, after this you will not be refunded for your flight. All refund requests must be made before the expiry of the validity of the ticket.
