Got an email today promising that if I bought a ticket today and travelled between 9/4 and 9/30, I'd get a coupon for 50% off a flight early 2025. However, when I look at the fine print it says, The instructions say:

Discount code terms

code:
EC2648
Please Note: This discount code cannot be redeemed until you receive your unique booking link, which will be sent to you in October 2024 via email upon meeting the offer conditions. The code is only valid for bookings made through the unique link provided.


When I follow the link in the email the discount code is populated in search, but when I try to buy a ticket I get a message saying the discount code has been redeemed already. Any insight? Or do I need to call reservations?
