Spirit Airlines and the future of cheap flights

Summary

This Planet Money episode uses [[SpiritAirlines|Spirit Airlines]] to explain the rise and stress of the U.S. [[UltraLowCostCarrierModel|ultra-low-cost carrier]] model. The first half revisits [[BenBaldanza|Ben Baldanza]]’s no-frills strategy: low base fares, dense seating, paid bags, onboard sales, cabin ads, and blunt acceptance of customer discomfort. The second half argues that Spirit was squeezed when legacy carriers copied budget pricing through [[BasicEconomyCopycatStrategy|basic economy]], loyalty programs made scale a competitive weapon, and post-pandemic costs rose faster than price-sensitive leisure demand.

Key Claims

• Spirit made the airline ticket narrower: the base fare bought transportation, while bags, seat choice, food, drinks, and some service interactions became separate paid items.
• Baldanza defended the model as a fairness story because passengers who did not use a service did not have to subsidize it.
• Customer surveys and passenger complaints understated the model’s appeal because many travelers still bought Spirit when the price gap was large enough.
• The episode uses Spirit to contrast stated preferences with revealed preferences: passengers said they hated the experience but often returned for cheaper fares.
• Legacy carriers such as [[DeltaAirLines|Delta Air Lines]], [[AmericanAirlines|American Airlines]], and [[UnitedAirlines|United Airlines]] copied the low upfront fare through basic economy while retaining larger networks and stronger loyalty programs.
• [[SeverinBorenstein|Severin Borenstein]] argues that loyalty programs can use incumbent scale to reduce customers’ willingness to compare flights on price alone.
• [[HenryHarteveldt|Henry Harteveldt]] says budget airlines have less room to absorb higher energy, material, labor, and pilot costs because cheap fares are the core product.
• The episode frames a possible federal stake or bailout for Spirit as unusual but economically relevant because Spirit’s disappearance could reduce fare pressure on larger airlines.

“stated preferences” - the episode’s label for what customers say they want.

“revenge of the legacy carriers” - [[GregRosalsky|Greg Rosalsky]]’s phrase for incumbent airlines copying and containing Spirit’s model.
