Understanding flight discount codes
Many airlines and travel agents offer flight discount codes, also known as voucher codes or promotional codes, which can be used to save you money.
Discount codes are usually percentage discounts or reduced prices offered for a certain period of time. Make sure you read the small print to get all the facts relating to your chosen discount code before booking.
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 2026/2027 tempt you into booking that weekend away or well earned break.
About Airline sales

Remember to check the terms and conditions of your chosen flight before booking, and contact the airline, flight booking engine or travel company directly with any specific questions.
