The demise of ultra low-cost carrier Spirit Airlines is expected to add further upward pressure to U.S. fares, according to experts.

Launched in 1992, the company is responsible for the ¡°Spirit Effect¡± in which bare-bones service opens up travel to a broader slate of customers otherwise priced out of the market.

Spirit¡¯s business model of stripped-down travel that includes no free meal service, baggage transport or other extras played a ¡°unique and disruptive role in the industry,¡± the U.S. Department of Justice argued in 2023, as it sought to block a merger with JetBlue.
