The Average Cost of Airfare: How Much Is a Plane Ticket?

The average cost of a domestic plane ticket is $428 as of the first quarter of 2026, the most recent period for which there is data from the Department of Transportation. That's up from $404 in the previous quarter and about $31 higher than the average price recorded in the first quarter of 2025.

The average cost of an international economy-class plane ticket is $1,217, according to FCM and Corporate Traveler. Keep in mind the cost of international airfare fluctuates more than domestic plane tickets depending on destination. It costs much more to fly to Japan from the United States than it does to fly to Canada, for example.

How much a plane ticket costs depends on a number of factors, including the price of jet fuel, passenger demand, seat capacity, the number of carriers flying a route, and economic conditions like inflation and consumer confidence.

How to save on plane tickets

Planning ahead and using credit cards and apps can make flights more affordable. Here are a few tips to help you save.

• Use a travel credit card or credit card points: Many travel credit cards offer points or miles for everyday purchases which can be redeemed for flights. Some cards include perks like a free checked bag or airport lounge access. Motley Fool Money has breakdowns of the best travel credit cards and the best airline credit cards if you want to dive deeper.
• Monitor plane ticket prices: Flight prices can change daily, so setting up price alerts can alert you to a deal when prices drop. Be patient and let the deals come to you.
• Avoid peak travel days: Airline tickets are usually more expensive on the weekends and during holidays. If you can be flexible, look to book mid-week, particularly Tuesday or Wednesday, to snag a cheaper seat.

A little planning and flexibility can go a long way in finding a cheaper flight -- which keeps more money in your pocket for the fun parts of your trip.
