Key Takeaways
- United Airlines ranks #1 globally in Available Seat Kilometres (ASKs), ahead of its US competitors, and as the airline continues to invest in long-haul services through 2025 it is poised to maintain this leadership.
- International capacity growth is triple domestic growth YoY, as the airline expands into Europe and Latin America - this includes low frequency and seasonal services to secondary markets using their newer wide-bodied aircraft types, where operating costs can be very competitive.
- Denver (DEN) remains the largest base for United Airlines with over half (55%) of traffic connecting through the airport.
- Amongst the three legacy US airlines, United had the highest average international economy class airfare in 2024 (US$1,005) despite a 10% decrease YoY, reflecting a softening market after the post-pandemic boom.
