Flying can be a significant expense, especially if you're travelling long distances or during peak season. However, there are a few things you can do to save money on flights, including using a discount code.

Here are a few tips on how to fly cheap:

Be flexible with your travel dates and times:

If you're able to fly on weekdays or during off-peak hours, you're more likely to find cheaper flights. Airlines typically offer lower fares for flights that are less popular.

Book your flights in advance:

The earlier you book, the more likely you are to get a good deal. Airlines often release their cheapest fares months in advance.

Use a flight search engine to compare prices:

There are a number of flight search engines available, such as Google Flights, Kayak and Skyscanner. These websites allow you to compare prices from different airlines and travel agencies.

Sign up for email alerts from airlines and travel agencies:

This way, you'll be notified of any sales or promotions. Many airlines and travel agencies offer exclusive discounts to their email subscribers.

Use a discount code:

There are a number of websites that offer discount codes for flights. Some of these websites include Groupon, LivingSocial, and RetailMeNot. Additionally, many airlines and travel agencies offer their own discount codes.

Here are some actual discount codes that you can use to save money on flights:

• Google Flights: Use the code GOOGLEFLIGHTS10 for 10% off your next flight.

When using a discount code, be sure to read the terms and conditions carefully. Some discount codes have restrictions, such as blackout dates or minimum purchase requirements.

Additional tips for saving money on flights:

• Fly into a smaller airport. Smaller airports often have lower landing fees, which can translate into lower fares for passengers.

• Consider flying on a budget airline. Budget airlines typically offer lower fares, but they may also have more restrictions, such as baggage fees and seat assignments.

• Pack light. The more baggage you have, the more you'll have to pay in baggage fees.
