United Airlines’ cargo story is woven into the broader evolution of aviation. Over the past century, the airline’s mission expanded from moving passengers across distances to moving goods across economies. What began with mailbags and small parcels has evolved into a global logistics operation supporting modern commerce at scale.
“Cargo has been part of United’s DNA since the earliest days of commercial aviation,” said Jan Krems, president of United Airlines Cargo. “What began with mailbags on early flights evolved into a worldwide logistics network that connects businesses and communities across continents.
“Our history matters because it shaped the discipline and reliability that customers depend on today. Cargo is not secondary to the airline’s mission. It is fundamental to how we support international trade and deliver value to our customers every day.”
In the early era of commercial aviation, freight had not yet emerged as an independent line of business. Mail and small shipments simply shared space with passengers. Yet even then, the essentials of today’s cargo discipline were forming: dependable schedules, operational rigor, and resilience under pressure.
The reliability required to transport mail would later become the backbone of international air freight. As aircraft became larger and networks extended across continents, air cargo shifted from supportive function to strategic enabler.

Industries discovered the competitive advantage of speed. High-value goods, urgent components, medical supplies, and perishables began to rely on air transport, reshaping how companies designed supply chains. Cargo was no longer an afterthought, it had become infrastructure.
Krems added: “Over time, air cargo moved from simply filling available space on an aircraft to becoming an essential pillar of the global economy. Industries today rely on predictable, high-quality air logistics to keep production moving, deliver life-saving medicines, and power the speed of modern commerce. At United Cargo, we see ourselves not just as a carrier, but as a partner to the industries that depend on reliable cross-border connectivity.”
The jet age accelerated that transformation. With long-range aircraft and expanding international connectivity, shipments could move between continents in hours instead of weeks. Air freight became a driver of globalisation, enabling tighter production cycles and new commercial models across industries.
Over time, complexity increased. Just-in-time manufacturing and globalised sourcing heightened dependence on predictable logistics. Customers demanded not just lift, but reliability and transparency. Visibility, consistency, and service quality became defining expectations.
Technology marked another turning point. Digital booking tools, automation, and analytics modernised cargo operations and replaced paper-based systems with integrated platforms. This shift enhanced precision and gave customers greater control over increasingly intricate supply chains.
Meanwhile, specialisation reshaped the product portfolio. Temperature-sensitive pharmaceuticals, valuable shipments, oversized freight, and time-critical goods required dedicated standards and expertise. Differentiation became central to delivering value, recognising that each shipment has unique operational needs.

“Today’s cargo environment requires specialised expertise,” explained Krems. “We continue to invest in digital tools that make booking easier and provide customers with real-time insight into their shipments.
“At the same time, our portfolio has evolved to support highly sensitive freight such as temperature-controlled pharmaceuticals and other critical shipments. That combination of digital capability and operational discipline is what allows us to deliver differentiated service in an increasingly complex logistics environment.”
In recent years, resilience has come to the forefront. Market volatility, global disruptions, and shifting trade flows have tested networks worldwide.
Cargo operations proved essential in maintaining the movement of critical goods, demonstrating adaptability through capacity adjustments and route optimisation when stability mattered most.
Krems added: “Over the past few years, our focus has been on building optionality into the network, strengthening our gateway strategy, and maintaining the operational discipline needed to keep goods moving even in volatile conditions. For our customers, reliability is not just a service attribute, it is a business necessity.”
Now, sustainability is guiding the next chapter. “As we look to the future, United is investing in sustainable aviation fuel (SAF), modernising the fleet, and supporting industry innovation that reduces the environmental footprint of air transport,” explained Krems. “Our goal is to continue enabling cross-border commerce while advancing toward a more responsible and efficient aviation ecosystem.
As aviation advances toward lower-emission operations through fleet modernisation and sustainable fuel initiatives, cargo plays a vital role in supporting environmental progress while maintaining efficiency.
Across a century of change, one principle has endured: purpose. United Cargo connects more than airports. It connects businesses to markets, patients to medicine, and communities to opportunity. Its legacy is not defined simply by longevity, but by the ability to evolve with the rhythm of international trade.
Aircraft may transport freight. But cargo moves economies and that movement never stands still.
“Cargo has always been about enabling progress. Whether it is supporting global supply chains, delivering critical healthcare products, or connecting businesses to new markets, our role is to keep the world moving forward.
“As we approach a century of aviation leadership, our focus remains clear: investing in innovation, strengthening our network, and continuing to deliver the reliability that customers expect from United Cargo,” concludes Krems.
