Who said anything about Spirit operating in a bubble where their failings timed with high oil? I didn’t. But the war and high jet fuel price may finish putting Spirit under, and get Frontier in serious trouble, and Avelo, and JetBlue….And the big airlines are feeling it too, even if they are still making money. That is a reality. Spirit may have exited bankruptcy were it not for all this.

Highly doubtful Spirit was going to exit bankruptcy regardless of high oil prices. Their plan involved selling literally everything for a set price, most of which were a little unrealistic as the assets are so niche (airline training centre, hotel that’s technically not a hotel, bright yellow HQ not even in downtown). Frontier will continue to exist even with these high oil prices, same with JetBlue. Are they hurting? No doubt but the only airline that is going to close up shop because of this oil crisis is Spirit, it’s simply the straw that broke the camels back. Their problems started long ago and its snowballed to this very moment.

Not really "screwing". These desert wars pop up pretty consistently about every ten years, airlines generally need to be positioned to deal with swings in fuel price. If it wasn't Iran, it would be something else.

While I was not in favor of this evolution, there is a possibility that it will be the last such disruption for the foreseeable future. Iran (and their proxies) were the last significant bad actors in the region. If IR can be constrained by whatever arrangement they negotiate.
