Sun Air International no longer showing up


#1

Sun Air International (FDY) flights to and from KPIT to KAOO and KJHW used to show up in tracking. They recently added service to KBFD and KFKL and introduced the Cessna Caravan to their fleet. Around the same time the PIT-AOO and PIT-JHW stopped appearing, the BFD and FKL flights have never appeared. But for some reason, the company’s LNS-PIT, LNS-IAD, and HGR-IAD flights are unaffected.

According to press in Bradford, KBFD-KPIT has begun operation.

Any insight into why these flights are not showing up? As a US-owned Part 135 operating under a callsign they should not be blockable.
