$CASS

This company is the ultimate example of "pick and shovel" business, referring to the famous tale of people got rich by selling pick and shovel during California gold rush, rather than directly participating in the risk gold mining itself.

Airlines business is very notoriously competitive and operating in low margin environment with many unpredictable variables, but $CASS as the "pick and shovel" of airlines will mostly be the main beneficiary of post-covid expansion of many foreign airlines which are very eager to pick the international-to-domestic routes that big players like $GIAA left behind, post restructure.
