Virus spread on shared seat armrests
Problem exists because airlines in their wisdom decided that in cattle class every seat should not have its own 2 armrests. There is little help in cleaning the bathroom frequently if the person in the seat beside you leave the virus on the armrest you both share. This could have been prevented if a 3+3 aircraft was 25cm/10inches wider so one could fit 4 more independent armrests. This would give space for extra 5cm/2inch wide armrests and a small gap between the armrests of adjacent seats. A gap that these days could be used for sample a dividing curtain, or a small shield to 100% ensure you don't touch your neighbour, or anything he/she touched, with the hand that soon will inadvertently be touching your face.
