Documented cause
WOW Air, founded by Skúli Mogensen in 2011, grew to become Iceland's second international airline offering ultra-low-cost transatlantic fares as low as $99. By 2018 it carried 3.5 million passengers but was hemorrhaging cash due to rapid fleet expansion funded by debt, rising fuel costs, and brutal competition from Icelandair and Norwegian Air. Multiple acquisition talks — with Icelandair in 2018 and Indigo Partners in early 2019 — collapsed at the last minute. On March 28, 2019, WOW Air abruptly ceased all operations, stranding 10,000+ passengers worldwide.
Lesson
“Ultra-low-cost aviation requires ruthless cost discipline; debt-fueled fleet growth at scale is existentially fragile.”
