• Spirit Airlines nears deal with Trump administration for $500 million rescue package.
• The airline has filed for bankruptcy twice and faces pressure from higher jet fuel costs.
• The deal could give the US government up to 90% ownership of the airline.
• The rescue package aims to create a durable, well-funded airline.

This potential deal may signal the Trump administration's willingness to support struggling airlines, which could have implications for the broader aviation industry. The investment may also indicate a shift in the government's approach to airline bailouts, which could set a precedent for future rescue packages and may influence the competitive landscape of the industry.
