I'm traveling, in fact on Saturday morning which will be the first day after the first missed federal paychecks. I'm very concerned about long lines (even with PreCheck--I hope--and CLEAR, plus high tier elite status and a premium cabin ticket) and just how early I must go to the airport, but not safety. If there are safety concerns, they center on the large numbers of people standing in a huge group landside at airports waiting to be screened.
