Cell phones on a plane wouldn’t bother me. When I think about the germs on an airplane I get nauseous. I wonder how many kids, or older adults, with leaky diapers sat in the seat on the previous flight. I’m so glad there is nobody I want to see that’s not within driving distance.
Bring a small bottle of hand sanitizer. Especially if you're going to fasten your seat belt. Oh yeah, that's required. The overhead luggage bin covers. There's the turn knob latch for the flip-down tray table. The armrest controls. Air-flow knob above you. All handled by the previous passengers, who may have lots of germs. Have a happy flight!
