How many miles do you need for a free flight?

You need 6,000 to 20,000 miles for a free one-way flight, depending on how far you're flying, which airline you're using and the dates of your travel. A one-way international flight will usually cost 35,000-50,000+ miles. Airline miles and points are generally worth around 1 cent each, but their value can vary.



The number of miles required for a "free" (award) flight has become highly dynamic in 2026, but generally, a domestic one-way flight in the U.S. starts at 5,000 to 12,500 miles. For international long-haul travel, such as a one-way trip from the U.S. to Europe, you typically need between 30,000 and 60,000 miles in Economy. Airlines like Delta and United now use "dynamic pricing," meaning the mile cost fluctuates with the cash price of the ticket. To get the best value, travelers often look for "Saver Awards." It is also important to remember that "free" is rarely truly free; even when paying with miles, you are still responsible for paying government-imposed taxes and fees, which can range from $5.60 for a domestic flight to over $200 for certain international routes.
