Air travel demand continued to surge in 2024, led by a bounce back in international trips.
From January through October alone, revenue-passenger miles worldwide, a demand metric, was up nearly 11% over last year, according to the International Air Transport Association. In 2025, IATA estimates aircraft departures of 40 million, up 4.6% from 2024.
Airlines scrambled to add flights and increase premium seating, which brings in higher revenue, especially on long-haul trips. Challenges from shortages of new aircraft to financial strife continued for some carriers, however, many passengers didn’t face the same flight disruptions as they did during acute staffing shortages coming out of the pandemic.
