Was the Iran war the final blow in the collapse of Spirit Airlines?

Spirit Airlines, a budget carrier in the United States, has begun winding down operations and cancelled all flights after talks with the Trump administration for a $500 million bailout failed. A spike in aviation fuel prices from the US-Israel war on Iran was a key factor in the airline's collapse, leaving 17,000 employees unemployed. Operating for 34 years, Spirit Airlines had filed for bankruptcy twice in recent years.
