GE employs a razor-and-blades model on an industrial scale, accepting losses on initial engine sales to powerful airframers like Boeing. This secures a multi-decade, high-margin stream of mandated service and parts revenue from a fragmented base of airline customers, where aftermarket sales can be 3-5 times the original engine price.

A weak economy can be beneficial for a market leader like Floor & Decor. While near-term earnings suffer, the downturn forces weaker competitors without structural advantages into bankruptcy. This ultimately allows the dominant player to capture significantly more market share during the eventual recovery.

Ryanair's success didn't just win market share; it fundamentally reshaped the entire European airline industry. Its model of unbundling every service to achieve the lowest base fare forced legacy carriers like British Airways to adopt similar 'low-cost tricks' to compete on short-haul routes. This has led to an industry-wide degradation of the passenger experience, where once-standard amenities are now paid add-ons.

While competitors retrench during recessions, Amphenol leverages its strong balance sheet to accelerate M&A. This counter-cyclical strategy allows it to acquire strategic assets at attractive valuations, ensuring it emerges from downturns with increased market share and strength.

China's airline industry, despite persistent losses, is a surprising beneficiary of the "anti-evolution" strategy. The sector doesn't suffer from seat oversupply, and strong regulatory coordination, rather than capacity cuts, could drive a significant turnaround.

GE serves two distinct customers: powerful airframers for the initial sale and a fragmented base of hundreds of airlines for aftermarket services. This split forces new entrants to solve a '3D puzzle' of satisfying both technically demanding OEMs and a global user base simultaneously, creating an immense and durable barrier to entry.

When Elon Musk publicly criticized Ryanair, the airline's CEO leveraged the conflict into a sales promotion. The resulting media attention and brand relevance led to a 2-3% increase in bookings, demonstrating how earned media from a public spat can be a direct and immediate revenue driver for a challenger brand.

The company's declining operating margins post-2017 were not a sign of weakness but a deliberate strategy. Management aggressively reinvested profits into logistics and payments, temporarily compressing margins to solidify long-term market dominance and build a powerful competitive moat.

The jet engine market is not a simple free-for-all. Competition is first structured by airframers like Boeing and Airbus, who decide whether to offer a single 'sole source' engine or 'dual source' options on a new aircraft. This initial strategic decision dictates the competitive landscape before airlines ever make their choice.
