Usually you're simply required to input the code at checkout on the retailer's website to get the discount. Discounted airline tickets might cover just one route or any number of routes in a particular country or destination.
Have a look and see if the latest flight discount codes 2025/2026 tempt you into booking that weekend away or well earned break.
