seatmates, a cast member, a PAPR hood

If everyone — no exceptions — stays masked at all times and there are many empty seats, flying should be fairly safe. The only surefire protection is a PAPR hood like those used in labs that work with lethal viruses. But those are expensive, hard to find and make you look like a cast member from “Contagion,” which might make your seatmates nervous.
