You got that right. Neighbor of mine is on the MIA 737 FO scheduling desk. He is pulling his hair out to get enough coverage.

He says it will continue to be so until all the furloughed FO are requalified, and to a lesser extent until enough new hires get though training. The first should be complete by end of August. The later likely will be through spring or summer of 2022 (unless the Epsilon variant has a major impact on flying.)
