Yes where a mask !! As far as sanitizing... there is the 4 Oz liquid limit. My step son is a flight attendant and he says the small pack of wipes are okay. But call your airline to find out there policy.

As BirdDancer said your more likely to be in a serious car accident. But you have a legit fear. Do you have a prn benzo by chance ? If so I’d take one prior to even getting to the airport as just getting to the plane gate can be very stressful.

Even with the mask on try to not touch your face at all. Most flu and crap are spread through germs having access to nose eyes and mouth , the mask will seriously decrease you chances of catching something.

Will you be home long ?
