US legacy carriers like Delta successfully neutralized low-cost threats (Spirit, Frontier) by introducing "Basic Economy" fares. Leveraging their scale and loyalty programs, they could price-discriminate, matching LCC prices on a fraction of their seats while maintaining premium pricing on the rest, effectively starving competitors of the price-sensitive traffic they relied on.

Though Spirit Airlines has shut down, its legacy is the "basic economy" fare class that fundamentally disrupted the airline industry. Major carriers were forced to adopt Spirit's unbundled pricing model to compete. This shows a company can fail while its core innovation becomes an industry standard.

Despite attractive growth, new airlines struggle to enter the Mexican market due to the incumbents' scale. Volaris and Viva, controlling a large portion of domestic capacity, can strategically add flights and slash prices on any route a new entrant attempts to serve. This pricing power ensures any startup would be driven to bankruptcy within months.

Beyond low fares, Ryanair's long-term dominance stems from its financial strategy of investing when the industry is weak. The airline uses its large cash reserves to place massive, discounted aircraft orders with manufacturers like Boeing during slumps and opportunistically seizes market share when legacy carriers falter. This turns competitors' crises into major growth opportunities.

The potential bailout of Spirit Airlines fundamentally misunderstands capitalism. Bankruptcy is not a bug to be fixed but a crucial feature that allows failing companies to restructure and adapt to market changes. Using public funds to prevent this process creates cronyism and props up unsustainable businesses.

The consistent history of government bailouts in the airline industry incentivizes risky financial behavior. CEOs know they can operate without a financial safety net because taxpayer money will likely rescue them in a crisis.

Airlines have massive fixed costs and low variable costs, but the leverage is capped by the number of seats. This creates intense pressure to sell the last seat at any price, crushing industry-wide pricing power and creating a situation with big downside and limited upside.

The potential bailout of Spirit Airlines highlights a debate over a key U.S. economic advantage: the ability to let businesses fail. Propping up 'zombie companies' misallocates scarce resources and harms healthier competitors, undermining the dynamic reallocation of capital that drives long-term productivity and growth.

The system often blamed as capitalism is distorted. True capitalism requires the risk of failure as a clearing mechanism. Today's system is closer to cronyism, where government interventions like bailouts and regulatory capture protect established players from failure.
