Aer Lingus sale dates aren’t fixed, but its flash sales have tended to cluster around the same times of year. Aer Lingus sales tend to arrive in September, January and around St Patrick’s Day in March. This year’s September sale launched on 7 September 2026, so based on previous years, expect the next one in January 2027, then another around mid-March 2027. Short flash sales can also appear in between with little notice.

When to expect the next Aer Lingus sale
Aer Lingus doesn’t publish a sale calendar. Its flash sales have tended to cluster around three moments: September, ahead of winter sun bookings; January, during the post-Christmas booking rush; and St Patrick’s Day in March. Outside those windows, one or two-day flash sales can appear with little notice.
| When to expect it next | What it usually covers | |
|---|---|---|
January | Early to mid-January 2027 | Short-haul European routes, some transatlantic fares |
St Patrick’s Day | Around mid-March 2027 | Ireland-linked and short-haul European routes |
September | September 2027 (2026 sale launched 7 September) | Winter sun and early next-summer fares |
“Aer Lingus won’t tell you when its next sale starts, but its habits give plenty away. The same three windows keep coming round, September, the January rush and St Patrick’s Day, while short flash sales pop up in between with barely any warning. This year’s September sale has already been and gone, so don’t wait for an announcement: check fares in early January, then again in mid-March.”Kate Acaster, Chief Editor, Flight Tribe
Aer Lingus sale dates: where to check for the next one
The fastest way to catch an Aer Lingus sale is to check aerlingus.com directly. Sales usually get a banner on the homepage and typically last only a few days, so there’s rarely much warning. AerClub members get sale emails, which is usually the earliest signal, and joining is free with no flight history needed. Our own flight deals page tracks verified Aer Lingus offers as they appear, so check it alongside the airline’s site.
How Aer Lingus sales compare with other airlines
Aer Lingus’s sale pattern is broadly similar to its low-cost rivals, though as a full-service airline it tends to run sales slightly less often. For airlines that run Black Friday sales, our tracker shows who has announced Black Friday flight deals for 2026.
- Ryanair runs flash sales more often than any other UK-facing carrier, sometimes several times a month.
- easyJet and Wizz Air sit in between, with sales every few weeks rather than constantly.
Because Aer Lingus flies both short-haul and transatlantic, its sales sometimes cover only one side of the business. A January sale might focus on European fares while transatlantic prices hold steady, so check the fine print rather than assuming an offer covers every route.
Tips for catching an Aer Lingus sale fare
Sale fares are limited on each route, so the cheapest seats tend to go within the first day or two. If you’re flexible, check a few days either side of your target dates, as a lower fare can turn up even after the headline price has gone. Aer Lingus sales don’t always cover every destination, 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?
Aer Lingus doesn’t confirm sale dates in advance, but its sales tend to arrive in September, January and around St Patrick’s Day in March. The 2026 September sale launched on 7 September, so based on previous years expect the next one in early to mid-January 2027, then around St Patrick’s Day in March 2027.
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.
