Make travel more affordable by using promo codes for flights the next time you book.
This guide shows you how promo codes for flights actually work, where to find them, and how to check whether a code really is your cheapest option.
What are promo codes for flights?
A promo code is a short string of letters and numbers you enter at checkout. It applies a set discount to your fare, either a percentage off or a flat dollar amount, subject to the code's terms. Airlines and online travel agencies use these codes to reward customers and encourage you to book directly with them.
A code isn't automatically the best deal, so it's worth comparing on Skyscanner first. Every Skyscanner search pulls live prices directly from airlines and travel providers, and we show you the full price up front. We don't take a cut, add fees, or mark anything up, so you can see whether the code price is genuinely the cheapest before you book direct.
How to find discount codes for flights
Promo codes come from airlines and online travel agencies. Here's where to look for them.
Sign up for newsletters: sign up for airline newsletters to get codes and offers sent straight to your inbox.
Check the airlines' websites: check airlines' own deals pages, where they post current promotions.
Follow social media accounts: follow airlines and travel agencies on social media, where codes are often shared first.
Use promo code websites: use promo-code aggregator sites like RetailMeNot, Honey, and CouponCabin to browse codes in one place.
How often do airline coupon codes appear?
How often codes appear varies by airline. Some rarely offer them, while others like Frontier run them regularly, and major US carriers such as American, United, and Delta also run periodic fare sales and codes. Popular times to watch include holidays, Black Friday, Cyber Monday, and Travel Tuesday.
Before you book, check the airline's or agency's deals page for what's live. Always read the fine print too, including the booking window, travel window, blackout dates, and other terms.
Flight promo codes: how to use them on Skyscanner
Here's how to put a promo code to work alongside Skyscanner in three steps.
Do a flight search on Skyscanner: run a flight search on Skyscanner to see options across airlines and agencies.
Compare airfare: compare fares side by side. Because Skyscanner shows live provider prices, you can see whether another airline's fare beats the code, or whether the code wins.
Book directly with the airline or travel agency: if the code is the best deal, select it and book direct on the airline or agency site, entering the code at checkout.
More ways to save on flights, all year round
A promo code is one tactic, but these three can stretch your budget further.
Sign up for loyalty programs: many airlines give members exclusive codes and perks, and booking direct after comparing lets you keep earning airline points.
Be flexible with dates: adjusting your travel dates can reveal cheaper fares.
Use Skyscanner's flight tools: try Whole Month search, Price Alerts, and Everywhere search to find the cheapest days and routes.

Final thoughts: finding and using promo codes for flights
A promo code can help you save, but it isn't always the cheapest option. Compare all the airlines on your route and look beyond the fare itself, including baggage, in-flight experience, and anything else your trip needs. Skyscanner makes this easy by showing your options side by side, so you can judge whether a promo code is truly the best overall deal.
