Severin Borenstein

Severin Borenstein is the economist interviewed in Spirit Airlines and the future of cheap flights about how large legacy airlines made life harder for Spirit Airlines and other budget carriers. The episode uses him to explain why incumbent scale can matter even when a cheaper carrier exists.

Borenstein’s key contribution is the Airline Loyalty Program Moat frame. He argues that co-branded credit cards, corporate partnerships, and frequent-flyer programs can leverage large route networks in ways that are not simply better service, making customers less likely to choose solely on price.
