Airlines often maintain suboptimal service levels due to a combination of high barriers to entry, market consolidation, and the "captive audience" nature of air travel. In 2026, many routes are dominated by only one or two carriers, meaning passengers have little choice but to fly with them despite poor reviews. Furthermore, the complexity of global operations—including weather, crew scheduling, and air traffic control—provides airlines with a "plausible deniability" for delays. While new 2024 DOT rules mandate automatic refunds for cancellations, enforcement can be slow, and airlines often use rigid scripts or chatbots to deflect complaints. Ultimately, because travelers prioritize price and route convenience over service quality in a low-margin industry, airlines are incentivized to cut costs in customer-facing areas while focusing on operational logistics.
