Episode notes
ULCC Consolidation Arrives
- Allegiant is buying Sun Country at a 20% premium to create a larger ultra-low-cost carrier.
- This is the first plausible merger between two U.S. ultra-low carriers and signals consolidation moving from theory to reality.
Divergent Financial Trajectories
- Sun Country has run steady ~10–12% operating margins and diversified cargo/charter revenue.
- Allegiant's margins slid from 21% in 2019 to ~5–7% recently, revealing productivity and demand issues.
Utilization Is A Hidden Constraint
- Allegiant's aircraft utilization fell ~20% versus 2019, hurting productivity despite a low-utilization business model.
- Causes include pilot shortages, pay increases without productivity gains, MAX delays, IT transitions, and weak Las Vegas demand.
