Aviation statistics: traffic, capacity, profits, and SAF in 2024
Air travel demand continued to outpace capacity across key markets in 2024, pushing load factors to multi-year highs and reshaping airline economics. With backlogs at Airbus and Boeing swelling and sustainable aviation fuel slowly scaling, carriers are navigating a complex data landscape that blends recovery with structural constraints.
Global traffic rebounds and demand mix shifts
In the Aviation sector, Passenger traffic sustained strong momentum through 2024 as airlines rebuilt networks and consumers treated air travel as a staple of post‑pandemic lifestyles. Global demand, measured in revenue passenger kilometers (RPKs), rose year over year and exceeded 2019 levels in most regions, while load factors hovered near historic highs. According to IATA’s monthly passenger market analysis, industry-wide load factors in peak months were in the low‑to‑mid‑80s, a sign of tight capacity relative to demand and disciplined scheduling by carriers according to IATA’s passenger market analysis.
The regional picture remained uneven but constructive. Asia‑Pacific’s catch‑up continued as border openings and intra‑regional tourism lifted international traffic, while North American domestic markets matured after two years of aggressive capacity restoration. Europe reached close to full recovery in flight volumes, supported by resilient leisure travel and a stabilized corporate segment. In fact, flights across the continent were roughly at the high‑90s percent of 2019 activity in 2024, with a full return and modest growth expected in 2025 based on EUROCONTROL’s aviation outlook.
Demand mix is also evolving. Premium‑economy adoption and upselling into flexible fares expanded as corporations recalibrated travel policies, while long‑haul leisure (“VFR” and premium leisure) continued to underpin transatlantic and transpacific yields. Airlines leaned on data‑driven merchandising to nudge travelers into higher fare families, helping maintain strong unit revenues even as capacity came back.
Capacity, operations, and efficiency metrics
Airlines added seats carefully in 2024, prioritizing routes and day‑of‑week patterns that maximized aircraft utilization. Available seat kilometers (ASKs) climbed more slowly than RPKs in many markets, which supported higher load factors and helped mitigate unit revenue pressure. On‑time performance improved through the summer versus prior years as staffing stabilized among airlines, airports, and air traffic control, and as schedule buffers were recalibrated to minimize missed connections.
Operational statistics reflected these adjustments: cancellations trended lower year over year in the second half, while average block times normalized with fewer tactical delays. Low‑cost carriers expanded intra‑Europe and short‑haul Asia aggressively, while U.S. majors and Middle East hubs focused on long‑haul connectivity and premium cabin density. Capacity management remained key to preserving margins where demand was most price‑sensitive.
