Overview

Low-Cost & Ultra-Low-Cost Carriers (LCC/ULCC) covers the airlines built on low fares and low costs — Southwest (the original LCC) and the ultra-low-cost carriers (Spirit, Frontier, Allegiant) that unbundle fares and charge for everything. They compete on price, drive fare competition, and serve price-sensitive leisure travelers.

Demand is driven by price-sensitive leisure travel, but the ULCC model has struggled recently — Spirit filed for bankruptcy (2024), the JetBlue-Spirit merger was blocked on antitrust grounds, and the majors' basic-economy fares have eroded the ULCC price advantage. It is a consolidating, pressured segment, with the ULCC model facing a reckoning as cost advantages narrow and the majors compete more aggressively on price; the model's economics are being seriously tested.
