Document Introduction

This report is prepared by the Office of Aviation and International Affairs of the U.S. Department of Transportation (DOT) to provide the public with deeper access to international aviation data. The report focuses on data for the fourth quarter of 2024 and the full year up to that point, with its core analysis targeting nonstop commercial flight traffic between U.S. airports and international points. The report explicitly states that although the global air travel system consists of complex and evolving networks and alliances, with most international travelers to/from the U.S. making at least one connection before reaching their final destination, these statistics are limited to nonstop traffic. Therefore, U.S. cities listed as international gateways in the report may show high traffic numbers, and users should note that some of these passengers will continue to their final destinations via connecting flights. Similarly, U.S. airlines may also serve certain international destinations only through international connection points, which may lead to data suggesting that U.S. carriers do not serve certain points or have a low market share in nonstop markets. This does not fully reflect their overall service capability provided through code-share and interline networks.

The data foundation of the report is the T-100 Segment Report, submitted monthly by U.S. and foreign airlines to the Bureau of Transportation Statistics' Office of Airline Information at the DOT. This dataset covers all nonstop international flight traffic to/from U.S. airports. The report highlights several important data usage limitations, including: data is confidential for six months after the reporting date; before October 1, 2002, carriers operating aircraft with 60 seats or fewer were not required to submit T-100 data, which may lead to an undercount of passenger traffic in specific markets (e.g., the Caribbean and some Canadian markets); data represents only nonstop service and cannot fully reflect services provided by U.S. carriers via connection points; the widespread use of code-share agreements means data is reported by the operating carrier, which may underestimate the ticket sales share of U.S. carriers in certain restricted markets (e.g., U.S.-China routes). Cargo data is similarly affected by network and code-share arrangements.

The report employs a top-down data presentation structure. It begins with an overall summary of U.S. international passengers, capacity, and cargo. Subsequently, data is broken down by world region and country, providing detailed data for the top 25 foreign country gateways (by passengers, seats, cargo), top 40 U.S. passenger gateways, top 40 international passenger gateways, and top 50 U.S.-international airport pairs. This data provides a solid quantitative basis for analyzing U.S. connectivity within the global aviation network, major trade and travel partners, and the competitive landscape between U.S. and foreign airlines.

Key annual data shows that in the 12 months ending December 2024, the number of available seats to/from the U.S. was 312.7 million, an increase of 8% compared to the previous 12 months. The seat share of U.S. airlines decreased by 1 percentage point to 51%, but they operated 57% of the flights. During this period, U.S. and foreign airlines transported a total of 256.9 million passengers, an 8% year-over-year increase, with U.S. airlines holding a 51% market share. In the same period, air cargo volume reached 12.52 million tons, a 6% year-over-year increase, with U.S. airlines holding a 47% share. Charter services accounted for 21% of international cargo.

Regional trend analysis indicates that Europe is the largest international regional gateway for the U.S., transporting 74.1 million passengers for the year, followed by Central America (57.2 million) and Canada (31.2 million). By country, the top five passenger gateways are Mexico, Canada, the United Kingdom, Germany, and the Dominican Republic. In terms of cargo, the Far East is the largest gateway, accounting for 42% of total U.S. international cargo. The top five cargo country gateways are China, South Korea, Hong Kong, Japan, and Germany. The report also details rankings and load factor information for major U.S. domestic and international hub airports, revealing the node distribution and operational efficiency of the aviation network.

This report provides policymakers, industry analysts, airline strategic planning departments, and academic researchers with authoritative, granular data on U.S. international air transportation activities. By understanding the patterns and limitations of this nonstop traffic, users can more accurately assess competition in specific route markets, identify growth areas, and provide data support for the formulation of aviation policies, infrastructure investments, and business strategies. All data is available on the DOT's designated website, along with links to download the broader international T-100 dataset.
