They will need more staff in the station surely? I cannot see any other way how they could have staff going around doing all the past duties on Air, then on top of that wiping each headset, ensuring they are secure on guests, dealing with any other issues etc...
I like the idea something brought up somewhere about guests being given some kind of thin glasses for hygiene, to separate your face from the actual headset. Staff going around with wet wipes doesn't sound like the greatest ideas. Will be interesting to see how it works in practice.
