What to do if your Aer Lingus discount code isn’t working
If your Aer Lingus discount code isn’t working, there are a few things to check:
Ensure the code is still valid, as expired promo codes cannot be redeemed.
Verify that your flight or fare type is eligible for the discount, as some codes may exclude certain destinations or ticket classes.
Double-check that the code was entered correctly, paying attention to spelling, spaces, and case sensitivity.
Make sure your booking meets any minimum spend requirements or other terms associated with the voucher.
If the code still doesn’t work, try another Aer Lingus promo code from our site, as we regularly update and test our deals to keep them active.
