These left the merchant feed within the last 60 days. A retired code sometimes still works at checkout, so it stays listed until the tracker drops it.
Aer Lingus publishes discounts more frequently than most Flights retailers, with a steady rotation of codes across the year rather than clustering around peak travel seasons. We track 20 live offers, reaching up to 25% off, which is a solid board for an airline. The mix of fixed dollar amounts and percentage codes means there is often a current option worth using, though the best discounts tend to cluster around off-peak travel windows.
Aer Lingus issues mostly fixed dollar discounts (17 codes) alongside a smaller set of percentage-based offers (3 codes), with the dollar amounts covering both sitewide bookings and per-person fares. No first-order-only codes appear in the feed, and the airline does not publish free shipping offers; Flights bookings do not involve shipping logistics. The predominance of flat amounts means you are comparing specific savings rather than percentage tiers, which simplifies the math at checkout but ties each code to a booking size.
Flights discounts typically widen in shoulder seasons (late winter to early spring and late summer to early autumn) when leisure travel dips and airlines fill seats with promotions; peak summer and December holidays see codes thin. Aer Lingus follows this rhythm, so waiting until March or September often surfaces deeper discounts than booking during high-demand windows. Onetravel runs a similar seasonal cycle, so comparing codes across both sites at the same moment tells you whether to move now or hold.
All 20 offers on this page come from merchant and affiliate network feeds, never from user submissions, and the whole page is matched against those feeds once a day. An offer that leaves the feed is retired the same day and stays listed as retired for 60 days, because a retired code often still works. Nobody here writes a code by hand and nobody places a test order, so we never tell you an offer worked for us. A code that fails for you goes to the desk queue through the report button the same day.
Offers last matched against the feed: October 1, 2026. Page notes written by Alina Marsh.
Offers on this page are ordered by how much they take off, not by how recent they are. Read the line under each one: it shows when the offer entered the tracker and, where the retailer states it, when it ends.
Codes are not printed in the page. Selecting an offer reveals the code and opens the retailer in a new tab at the same time, so you can paste it straight into the cart.
Enter the code in the promo or discount field and confirm the total changes before completing the order. A code that applies but takes off less than expected usually means part of the cart is excluded.
If the offer does not apply, use the report button on this page. It goes to the desk queue the same day, and an offer that fails twice is retired.
20 offers are live on this page right now. All of them need a code at checkout. The page was last matched against the merchant feed on October 1, 2026.
The deepest discount on this page takes 25% off. 7 of the current offers read as sitewide, so they are not tied to one product line.
Not in the current set. None of the offers on this page are marked for first orders only, so what you see applies whether or not you have ordered before.
Check the terms under the offer first: most rejections come from a spend threshold, an excluded product line, or a first order restriction. If the code still fails, use the report button on this page. It goes to the desk queue the same day, and a code that fails twice is retired.
Alina covers travel retailers and booking services for Couptic. She notes blackout terms and booking windows, because a travel code is usually tied to when you book rather than when you travel.
