I looked up the numbers in Yahoo Finance and found CAL rev/debt 14.6Bil/5.36Bil United $19.2B rev/$7B debt AMR $23.3B rev/$8.8B debt DAL $24.6B rev/$14.7B debt and for example Jet Blue $3.3B rev/$3.5B debt. CAL has $2.72 in revenue for every dollar of debt and DAL only has $1.67 in revenue for a dollar of debt. No one is calling for DAL to be going BK soon so I don't see it anytime soon for CAL.
