Remember folks, if it's a warn notice, you have 90 days to look for a job. If you wait out the 90 days and then officially released, go apply for unemployment even with severance you can apply (and receive) unemployment. Some people I worked with when all of this happened with a warn notice began working for another company and collected 2 checks (one from Sabre and one from their new employer).
Took this from @O3JWdxu-6wfr for useful info.
