what the loss of spirit means for flight prices

Spirit Airlines' exit reduces ultra-low-cost capacity in the US domestic market, potentially leading to higher average fares on routes where Spirit competed. Legacy carriers (American, JetBlue, Frontier) are absorbing some capacity, but the removal of a low-price leader may reduce pricing pressure. Impact is US-specific and concentrated in leisure routes. No direct commodity or input scarcity is created; the mechanism is reduced supply in a specific market segment.
