The reason is that the market is pricing in a removal of capacity in the marketplace, which should enable more pricing power, notably for the budget airlines that Spirit competes directly, and also with network carriers like American Airlines whose ticket prices are also pulled down by competition from budget carriers on specific domestic routes.

That's why the Spirit news is taken as a positive.

That said, it makes more sense to buy best-in-class stocks like Delta Air Lines and United Airlines.
