Top Largest Cargo Airports in the United States

Overview of US Cargo Airports

The United States operates over 19,000 airports nationwide, with more than 5,000 public facilities, though only about 50 airports handle significant commercial cargo operations. The US cargo airport system ranks as the world's largest and most efficient, with six American airports consistently appearing in the global top 20 for cargo volume and collectively handling nearly half of North America's air freight.

US cargo airports fall into two distinct categories: dedicated freight facilities and dual-purpose airports that handle both passengers and cargo. Dedicated cargo hubs like Memphis and Louisville operate primarily for express carriers such as FedEx and UPS, while major passenger airports like Los Angeles and Miami incorporate substantial cargo operations within their broader infrastructure.

What Are the Busiest Cargo Airports?

The busiest cargo airports in America handle everything from overnight letters to industrial machinery, with operations spanning 24 hours a day. Ted Stevens Anchorage International Airport leads the nation by some metrics primarily due to its strategic location on polar routes between Asia and North America. Memphis and Louisville dominate as the superhubs for FedEx and UPS respectively, processing millions of packages nightly for next-day delivery.

US Cargo Industry Statistics

The US air cargo industry demonstrates remarkable resilience and growth, with American airports collectively handling over 150 billion pounds of cargo annually, representing approximately 45% of global air freight volume. The sector experienced 11.3% growth in 2024 compared to 2023, marking a new record.

Why Cargo Airports Matter for Logistics

Cargo airports serve as critical nodes enabling just-in-time manufacturing, e-commerce fulfillment, and global trade. During the COVID-19 pandemic, air cargo operations maintained supply chain resilience by rapidly adapting to transport essential goods, medical supplies, and vaccines while passenger flights were grounded — demonstrating their ability to provide backup capacity during maritime shipping disruptions.

The speed advantage of air cargo — delivering goods in hours rather than days or weeks — allows businesses to minimize inventory costs, respond rapidly to market demands, and maintain lean supply chains impossible with ocean or ground transportation alone. Furthermore, cargo airports generate substantial economic benefits, attracting logistics companies, warehousing operations, and manufacturing facilities that cluster around these transportation hubs.

Top 5 Largest Cargo Airports by Volume

Rankings and Comparison

The gap between the top three cargo airports and the rest of the field is substantial, with Memphis, Anchorage, and Louisville collectively handling over 11.4 million short tons annually — more than 50% of the top five's combined volume. Louisville stands out as the fastest-growing major cargo airport in 2024, with its 16% year-over-year increase nearly doubling the international average growth rate.

Global Ranking Context

American airports maintain a strong presence in global cargo rankings, with six US facilities placing among the world's top 20 busiest cargo airports in 2024. However, Asian airports have increasingly dominated the upper rankings, with Hong Kong International Airport holding the number one global position.

Memphis International Airport (MEM)

Memphis International Airport stands as the busiest cargo airport in North America and ranks among the top cargo facilities worldwide. Located in Shelby County, Tennessee, approximately 7 miles southeast of downtown Memphis, this 3,900-acre facility serves as the beating heart of global express shipping operations. The airport can reach approximately 75% of the American population within a 24-hour drive, making it invaluable for both domestic and international freight distribution.

Cargo Operations Overview

Memphis International Airport operates as a 24/7 cargo facility, processing approximately 400 flights daily, with the majority occurring during nighttime hours to optimize the hub-and-spoke distribution model. The facility's operations are uniquely structured to accommodate the rapid sorting and redistribution of packages — cargo aircraft typically spend just a few hours on the ground before departing. Passenger and cargo activities operate independently to prevent interference between high-volume nighttime freight sorting and daytime passenger flights.

Major Carriers (FedEx Hub)

FedEx Express chose Memphis as its global superhub in 1973 due to the city's central geographic location, temperate climate that minimizes weather-related delays, and favorable business environment. During peak sorting operations (midnight to 4 AM), the facility processes up to 180,000 packages and 245,000 documents per hour.

Facilities & Infrastructure

Memphis International Airport's infrastructure is purpose-built to support high-volume cargo operations. The four runways accommodate the largest cargo aircraft in operation, including Boeing 777 freighters and MD-11 aircraft. The airport maintains a dedicated de-icing facility capable of servicing 12 wide-body aircraft simultaneously, completed in 2022 at a cost of $309 million to ensure year-round operational reliability.

Ted Stevens Anchorage International Airport (ANC)

Ted Stevens Anchorage International Airport stands as a dominant force in global air cargo logistics, ranking as the second-busiest cargo airport in the United States. In 2024, ANC handled approximately 3.5 million metric tons (7.7 billion pounds) of cargo. The airport employs over 15,000 people directly and indirectly, contributing approximately $1.8 billion annually to Alaska's economy.

Strategic Trans-Pacific Hub Location

Anchorage's geographic position places it at the intersection of the Great Circle Route — the shortest flight path between Asia and North America. The airport sits within 9.5 hours flying time of 90% of the industrialized world, making it equidistant from major markets in Tokyo, Beijing, Seoul, and cities across the Lower 48 states.

By stopping in Anchorage, cargo carriers can load an additional 100,000 pounds (45,359 kg) of revenue cargo compared to direct trans-Pacific flights that must carry excessive fuel displacing cargo capacity. Approximately 80% of all trans-Pacific cargo flights make technical stops at ANC for refueling, crew changes, and cargo transfers.

Other Major US Cargo Airports

Beyond the top five, several other airports play crucial roles in the US air freight ecosystem:

• Los Angeles International (LAX) — The primary West Coast gateway for trans-Pacific trade, handling approximately 3.9 million short tons. LAX processes enormous volumes of Asian manufactured goods alongside US agricultural and technology exports, supported by proximity to the Port of Los Angeles.
• Chicago O'Hare International (ORD) — A central US distribution hub handling approximately 1.6 million short tons, serving as a critical node for both domestic and international cargo with connections across North America and Europe.
• John F. Kennedy International (JFK) — The primary gateway for high-value international cargo from Europe, the Middle East, and Asia, specializing in luxury goods, pharmaceuticals, and time-sensitive shipments.
• Indianapolis International (IND) — FedEx's second-largest US hub, handling approximately 1.1 million short tons and providing crucial backup capacity for the Memphis superhub during peak periods.
• Cincinnati/Northern Kentucky (CVG) — One of the fastest-growing cargo airports in the US, serving as a major hub for Amazon Air and DHL's Americas operations with a strategic location providing next-day delivery reach to major eastern US population centers.
