The Center for Disease Control and Prevention has an important update for frequent fliers...there's no need for a COVID test on domestic flights.
The CDC still recommends that passengers take precautions, and that "If someone must travel, they should get tested with a viral test 1-3 days before the trip."
The CDC also recommends that travelers are be encouraged to do further testing after they fly.
"After travel, getting tested with a viral test 3-5 days post-travel and staying home and self-quarantining for 7 days, even if test results are negative, is a recommended public health measure to reduce risk.".
