Most travelers assume the three major U.S. carriers are indistinguishable clones, but Sam Denby reveals a hidden battlefield where the real war is fought not on price, but on the invisible architecture of route maps. This piece cuts through the noise of fare wars to expose a fascinating strategic divergence: while competitors play it safe, one carrier is betting its future on inducing demand for destinations that data says shouldn't exist.
The Oligopoly Trap
Denby begins by dismantling the illusion of competition in the skies. He points out that United, American, and Delta have converged so thoroughly on product that they are practically mirror images. "When one of them eliminates change fees, they all eliminate change fees. When one of them announces free Wi-Fi, they all announce free Wi-Fi," Denby writes. This observation is crucial because it explains why the airlines have stopped fighting on price. In an oligopoly, price competition is mutually destructive, so the carriers have quietly agreed to standardize their offerings to protect margins.
The author notes that this lack of differentiation leaves only one arena for competition: the network itself. "Subtly, each of the three largest US airlines has carved out a small niche for themselves through the nuances of the design of their route networks," he argues. This framing is effective because it shifts the reader's focus from the seat they sit in to the map they are flying over. The real product isn't the flight; it's the connection.
If one player makes a change, they all follow in suits that no one of the three gains a meaningful differentiation.
The Gamble on Induced Demand
The most compelling section of Denby's analysis focuses on United Airlines' willingness to take risks that its rivals refuse to touch. He uses the example of a flight from Washington, D.C., to Anchorage, Alaska. Geographically, the route makes little sense; D.C. is a terrible connecting hub for Alaska, and the flight pushes the limits of the aircraft's range, making it fuel-inefficient. Yet, United launched it anyway.
Denby explains the logic: "United really competes on network depth... They spread their operations out and focus on breadth versus depth." While American and Delta stick to proven, high-volume routes, United is willing to serve obscure destinations like Farmington, New Mexico, or Laramie, Wyoming. The author suggests this is a calculated gamble on "induced demand." The airline isn't just capturing existing travelers; it's convincing people to change their plans to fly non-stop to places they previously would have connected through a hub.
This strategy is most visible in United's international expansion. While competitors fly to Tokyo, United flies to Osaka. While others stop at Auckland, United pushes on to Christchurch. Denby highlights the difficulty of justifying these routes with traditional data. "When starting a route domestically, much of the decision can be made by looking at traffic pattern data... But it's unlikely that the numbers directly demonstrated that for a relatively minor longhaul market like Christchurch," he writes. Instead, the airline is betting on its ability to shape consumer behavior.
Critics might argue that this approach is financially reckless, especially in a volatile economic climate where fuel costs and exchange rates can wipe out thin margins instantly. However, Denby counters this by noting that if United is right, they can "essentially monopolize the market before American, Delta, or another competitor can enter."
Turning Weakness into Strength
The commentary takes a sharp turn when analyzing how United exploits the structural weaknesses of its partners. In Europe, United's joint venture with the Lufthansa Group forces connections through Frankfurt or Munich, which are often geographically inefficient for travelers heading to the southwest of the continent. Denby points out that this creates a gap in the market. "The vast majority of United's non-stop flights to Europe sit to the southwest of the Lufthansa group's primary hubs, as this is the area of Europe least effectively served by them," he observes.
By flying non-stop to cities like Faro, Portugal, or Malaga, United offers a faster itinerary than any competitor, effectively cornering a market that its own partners ignore. This is a masterclass in strategic positioning. "They've proven the only airline, American or otherwise, able to make the economics of a transatlantic flight work, meaning they have these markets cornered," Denby asserts. This evidence is strong because it shows how a carrier can turn a partnership's limitation into its own competitive advantage.
United has tried routes to the north and east where the Lufthansa hubs would be more comparatively competitive. They used to fly to Hamburg, but that stopped in 2018. They used to fly to Prague, but that stopped in 2019 after a single disastrous summer.
The American Counter-Strategy
In stark contrast, Denby describes American Airlines' approach as one of pragmatic minimalism. American is the largest carrier by passenger count but the least adventurous in network design. "Our Shorehole network is the foundation of value for customers and investors," Denby quotes from a 2024 investor presentation, highlighting the airline's focus on domestic dominance. Internationally, American relies heavily on its partnership with British Airways, using London as a massive, low-risk connecting hub.
This strategy makes sense for American's business model. They don't need to build a global network from scratch; they just need to get their corporate clients from Dallas to Stockholm efficiently. London is the perfect bridge. "London is a fantastic European connecting hub because it's geographically positioned at the entry point to the continent coming from America and it's home to British Airways which offers a huge network of well-timed connecting flights into the continent," Denby explains.
However, this reliance on a single partner creates a vulnerability. If the British Airways network falters or if the joint venture dynamics shift, American's global reach could shrink rapidly. Denby implies that while this strategy is safe, it lacks the agility to capture the growing leisure travel market to far-flung destinations where United is already establishing a monopoly.
Bottom Line
Denby's analysis succeeds in revealing that the airline industry's most significant battles are being fought on the drawing board, not in the terminal. The strongest part of his argument is the demonstration of how United's risk tolerance allows it to create new markets rather than just competing for existing ones. The biggest vulnerability in this strategy is the reliance on inducing demand in a world where leisure travel is increasingly sensitive to economic downturns. For the busy traveler, the takeaway is clear: the airline you choose isn't just about the seat you get, but the map they are willing to draw for you.
