A summer travel paradox has emerged: Even though international flights use considerably more jet fuel than domestic travel, the cost to fly within the U.S. has skyrocketed at rates far beyond that of flying abroad.
According to data from airfare search engine Skiplagged, domestic flight price growth has increased 23.2% from March 2025 to this month, while international flight costs have increased 11.5% in the same time period. This summer marks the highest domestic passenger prices for the season since 2022.
