Why are flights so expensive in June?

There are far fewer seats available than before the pandemic, as airlines have struggled to return to normal capacity. There aren't enough planes or pilots. We are also seeing increased demand. All of it adds up to higher prices.



Flights in June are expensive primarily due to the "Perfect Storm" of peak demand and limited capacity. As schools break for summer and families plan vacations, the surge in travelers allows airlines to use "dynamic pricing" AI to maximize profits, moving tickets into higher "fare buckets" as seats sell out. In 2026, this is exacerbated by supply chain issues that have delayed the delivery of new, more efficient aircraft, forcing airlines to operate with a "ghost fleet" of older planes or reduced schedules. Additionally, June marks the start of the "Green Tax" season in many regions, where environmental surcharges and the cost of Sustainable Aviation Fuel (SAF) are passed directly to the consumer. High fuel costs and recent labor settlements with pilot unions also contribute to a higher "floor" for ticket prices that travelers rarely saw in previous decades.
