How would this work (or what is the purpose) for seats with no seat storage?
What's the difference between putting your bag on the floor where everyone else has put a bag, and putting it in the bin? The bin actually has surfaces that are easier to disinfect.
Shouldn't people be far more worried about all the surfaces that people are actually touching, all the time, while onboard? I remember when CI proposed not having ground staff clean tray tables on outstation turnarounds, the CI FAs threatened to go on strike.
