Sun Country Has Become Allegiant — And That’s The Real Problem

In May 2026, while the aviation press was covering JetBlue's retreat, Spirit's collapse, and Frontier's identity crisis, two airlines almost nobody was writing about completed a $1.5 billion merger that created the most profitable leisure carrier in the United States. Allegiant Travel Company acquired Sun Country Airlines. Sun Country had posted 13 consecutive profitable quarters. Allegiant's Q1 2026 profit rose 32% year-on-year. Neither airline has a founder warning the industry to brace for bankruptcy. This video explains the full story: why Allegiant's secondary-city monopoly model is more defensible than Spirit's volume model ever was, what Sun Country's three-legged stool of scheduled service, charter, and Amazon cargo actually does to airline economics, why the man who built Sun Country learned everything he knew from Allegiant in the first place, and what the combined entity means for the future of US leisure aviation.
