Private planes are the only exemption currently, not Charter planes. "People on board the following categories of conveyances continue to be exempt from the requirement to wear a mask: Private conveyances operated only for personal, non-commercial use;"

Irony not lost on me. In regard to our flight, TSA exempts private, non-commercial flights from the mask requirement. #txlege had been meeting at the Capitol w/o masks for several months, & we continued that practice as we had all been fully vaccinated. 1/
