Olympic Air Promo Codes & Coupons February 2026

Your Olympic Air promo code is likely invalid at the final payment step because it has expired, doesn't match your selected route or dates, or violates exclusions like international-to-international flights.

Common scenarios include codes like "S2024" (20% off Athens-Kos round trips, valid only 7-12 July) failing on non-qualifying dates, or third-party codes from coupon sites not syncing with Olympic Air's system, triggering "Invalid promotional code" errors. Codes are entered in the 'Promotional Code' field during booking, but validation runs fully at payment against real-time inventory.

Step-by-step fix:

1. Verify code terms on olympicair.com (e.g., 20% off international flights valid 01/02/2026-28/02/2026 for travel until 31/03/2026).
2. Clear browser cache/cookies or switch devices, as checkout glitches occur mid-process.
3. Test on desktop site first—mobile may cache old sessions.
4. Contact support via live chat if code shows "verified" but fails.

Pro tip: Always cross-check code validity dates and routes directly on Olympic Air's site before checkout to avoid last-minute invalid errors.

No, Olympic Air does not allow combining multiple promo codes on a single booking; only one code applies per transaction.

This policy prevents stacking, as seen in user reports where entering a second code after the first (e.g., COSMOTE 20€ off domestic + 15% sitewide) triggers "Only one promotional code allowed" errors during checkout. Partner deals like MAGENTA MOMENTS are single-use only, per terms.

Step-by-step workaround:

1. Compare discounts manually—pick the highest value (e.g., 40% off eligible categories via AST40 vs. 20% international).
2. Apply the best code in the 'Promotional Code' field post-passenger/destination selection.
3. Complete payment; no multi-code field exists.

Pro tip: Test codes separately in incognito mode on olympicair.com to preview savings before finalizing your best single-code option.

Olympic Air promo codes apply only to specific routes and categories, not all flights—e.g., 20% off international/selected domestic, but excluded on international-to-international routes from 01/07/2024-26/10/2024.

Deals like flights to Thessaloniki from €30 or Heraklion €45 target Greek domestic routes, while codes like S2024 limit to Athens-Kos Economy Comfort Flex. Seasonal patterns: 50% off Jan-Mar, 40% Mar-Jun, 30% Jul-Oct.

Common issues: Codes fail on non-listed routes, showing "Not applicable to this itinerary."

Step-by-step check:

1. Enter destinations/dates first on olympicair.com.
2. Input code at promo field—system flags ineligible routes instantly.
3. Review terms for exclusions (e.g., no int'l-int'l discounts).

Pro tip: Search Olympic Air's flight deals page first for route-specific promos to match your itinerary perfectly.

Olympic Air promo codes work the same on the mobile app and website, but app users report more frequent caching issues causing "invalid code" errors not seen on desktop.

Both use the identical 'Promotional Code' field during booking, with codes like COSMOTE DEALS applying equally if terms match (e.g., 20% off 01/02/2026-28/02/2026). App glitches stem from auto-saved sessions; website is more reliable for third-party codes from sites like Knoji.

Step-by-step solution:

1. Force-close/reopen app or use browser version.
2. Enter code after full itinerary selection.
3. If fails, switch to desktop site for confirmation.

Pro tip: Bookmark olympicair.com desktop on mobile for seamless code entry, bypassing app sync delays.

If your verified Olympic Air promo code isn't applying the correct discount, it's often because base fares already include reductions or the code caps at certain categories, like 20% off shown but only 15% applied due to fuel surcharges.

Users experience this with codes like AST40 (up to 40% off eligible), where final math excludes taxes, per checkout preview. Terms note fares are pre-reduced (e.g., 50%/40%/30% seasonal).

Step-by-step resolution:

1. Screenshot checkout showing mismatch and note exact fare breakdown.
2. Re-enter code or refresh page—inventory changes affect %.
3. Email support@olympicair.com with booking ref, code, and screenshot; response in 24-48h.
4. Verify via partner sites (e.g., Cosmote for 20€/30€ off specifics).

Pro tip: Calculate expected savings manually from code terms before payment, and use live chat during peak hours (9AM-6PM UTC) for instant fixes.
