June 9th is when F9 has its 1110 filing. My understanding of the history that led to the current Ch 11 process goes thus:
1. Lorenzo files Ch 11, and stops paying the leasing companies. Leasing companies say "fine, we'll take back out planes". Lorenzo says "you can't do that - I have protection".
2. Lorenzo voids employee contracts, says "you're all fired, but we'll hire you back at 1/2 pay.
3. In response, new laws are passed, allowing vendor/lease payments to be halted with Ch 11 filing, but requiring that an 1110 be filed within 60 days. At that point, the company needs to have renegotiated the payments and make back payments with vendors, or face repossession of assets.
4. New laws require companies to negotiate with employees, and allows the company to file an 1113 motion if an agreement cannot be reached with employees. In the 1113 filing, the company can ask the judge to impose cuts on the employees, or void the contract altogether. To the best of my knowledge, an 1113 motion has never gone well for the employee group in question.
