Columbia Business School’s Professor Brett House spoke with Vox about how airlines such as Delta are increasingly relying on premium seating, upgrades, and add-on fees to drive profitability. Drawing on his expertise in macroeconomics and financial systems, Professor House explained how this shift reflects broader changes in corporate pricing strategies and consumer behavior, particularly in an environment of higher costs and tighter margins. His commentary highlights how airlines are reshaping the economics of air travel—creating a more segmented flying experience while prioritizing revenue from higher-income and business travelers.
