Friends of mine are in Europe, they have to come home in another couple of weeks. We’ve talked about getting masks, wipes, and rubbing alcohol, the 90% alcohol kind that kills viruses. Wear clothes on flights that you were going to throw out anyway and toss them. Especially things like cheap raincoats. Scarves, gloves, other disposable protective gear. Fly during nonrush hours. Look around the cabin before takeoff and if you don’t like the looks of other passengers, get off immediately.
Have fun.
