- Spirit Airlines collapsed last month after carrying only 2% of the flying public, per University of Utah economist Scott Schaefer — the void is small in passenger share, but the U.S. low-cost seat count has still dropped heading into peak summer travel.
- Delta Air Lines posted record 2025 revenue of $58.3 billion but sold $1.1 billion less in economy tickets year-over-year, with 60% of revenue now coming from premium cabins, loyalty programs, and cargo.
- United Airlines reported 2025 adjusted net profit of $3.5 billion (up 6%) with premium seat revenue jumping 11%; CEO Ed Bastian described a 'K-shape' bifurcation where premium demand thrives while the lower-end consumer struggles.
- U.S. carriers spent $5.06 billion on jet fuel in March 2026, up 56.4% from February's $3.23 billion and 30% above March 2025, with prices whipsawed by Strait of Hormuz reopenings and closures.
- Allegiant completed its acquisition of Sun Country in May, with its CEO calling the deal a move to create a 'more differentiated and durable airline' — one of the few paths open to smaller carriers seeking the scale needed to compete.
- Southwest ended its no-assigned-seats model earlier this year and pulled out of O'Hare this month to consolidate at Midway, while JetBlue is dropping Manchester, NH service July 7 and cutting flights at LaGuardia and Newark.
- Breeze Airways rejects the ULCC label entirely, focusing on nonstop service from underserved secondary airports and citing a 95% airport retention rate; founder David Neeleman's 2027 IPO target has no public update.
Why it matters: The post-Spirit vacuum is small in passenger share (just 2%) but structurally huge: with jet fuel up 56.4% month-over-month and the Big Three monetizing premium seats and loyalty programs at record levels, mid-size LCCs like Allegiant and Breeze must either merge for scale or retreat to second-tier cities — meaning fewer cheap seats for cost-sensitive summer travelers.
