It was repositioned to Tampa International in August 2020 and has remained stored at the Floridian airport ever since, Flightradar24 ADS-B data shows. The aircraft will be converted by Commercial Jet in Dothan, AL, and is scheduled to enter into conversion in June 2021.

A forecasted delivery timeline has not been announced.

Two of the freighters are active on cargo runs within Hawaii, while the other two aircraft are in storage. Trans Executive Airlines also owns Transair Hawaii, which operates an additional two B737-200 dedicated freighters active within Hawaii.
