Aer Lingus sale dates aren’t fixed to a calendar. The airline runs flash sales through the year rather than on set dates, so the honest answer to “when is the next Aer Lingus sale” is: keep watching, because there’s no confirmed schedule to plan around.
This guide covers how often Aer Lingus sales tend to land, what they typically include, and how that compares with Ryanair, easyJet and Wizz Air. For hand luggage rules on Aer Lingus, see our carry-on bag guide.
How often does Aer Lingus run sales?
Aer Lingus doesn’t publish a sale calendar, but flash sales have historically clustered around a handful of predictable moments: January (the post-Christmas booking rush), around St Patrick’s Day in March, and again in autumn ahead of winter sun bookings. Outside those windows, shorter one or two-day flash sales can appear with little notice.
| Typical window | What’s usually included | |
|---|---|---|
January | Early to mid-January | Short-haul European routes, some transatlantic fares |
March | Around St Patrick’s Day | Ireland-linked and short-haul European routes |
Autumn | September to November | Winter sun and early next-summer fares |
Aer Lingus sale dates: where to check for the next one

The fastest way to catch a live Aer Lingus sale is to check aerlingus.com directly. Sales are usually flagged with a banner on the homepage and typically last only a few days, so there’s rarely much advance warning.
AerClub members get sale notifications by email, which is usually the earliest signal available. Signing up is free and doesn’t require any flight history. Our own flight deals page tracks verified Aer Lingus offers as they appear, so it’s worth checking alongside the airline’s own site.
How Aer Lingus sales compare with other airlines
Aer Lingus’s sale pattern is broadly similar to its low-cost competitors, though its full-service positioning means sales tend to be slightly less frequent than Ryanair’s. Ryanair runs flash sales the most often of any UK-facing carrier, sometimes multiple times a month. easyJet and Wizz Air sit somewhere in between, with sales appearing every few weeks rather than constantly.
Because Aer Lingus operates a mixed short-haul and transatlantic network, its sales sometimes apply to only one side of the business. A January sale might focus on European short-haul fares while transatlantic pricing holds steady, so it’s worth checking the fine print on any offer rather than assuming it covers every route.
Tips for catching an Aer Lingus sale fare

Sale fares are usually limited in number on each route, so the cheapest seats tend to go within the first day or two. If you’re flexible on dates, checking a few days either side of your target dates can surface a lower fare even after the headline sale price has sold out.
It’s also worth checking whether a sale applies to your specific route before booking elsewhere. Aer Lingus sales don’t always cover every destination it flies to, and regional UK departures via Dublin sometimes get separate, smaller promotions than the main London routes.
Frequently asked questions
When is the next Aer Lingus sale?
There’s no confirmed date. Aer Lingus doesn’t publish a sale calendar, though flash sales have historically clustered around January, March (St Patrick’s Day) and autumn.
How long do Aer Lingus sales usually last?
Most Aer Lingus flash sales last only a few days, and the cheapest fares on popular routes can sell out within the first day or two.
Do Aer Lingus sales cover transatlantic routes?
Sometimes, but not always. Sales occasionally focus on short-haul European routes only, so it’s worth checking whether your specific route is included before booking.
Is it worth joining AerClub for sale alerts?
Yes. AerClub is free to join and members typically get sale notifications by email before or as a sale goes live, which is usually the earliest signal available.
Are Aer Lingus sale fares refundable?
Sale fares are usually the airline’s lowest, most restrictive fare class, so they typically carry limited change or refund flexibility. Check the fare conditions before booking.
