As one of the few people I see who still wears a mask on airplanes, I think back and wonder how this wasn't always a thing, even before COVID.
Travelers are in a closed space for a prolonged period of time sharing possibly-infected air with people who have been all around the world and likely in close company with even more people.
COVID or not, wearing a mask is only a minor inconvenience and it shouldn't even be a question about whether or not to wear one, provided you care about your own health and/ or the health of others.
Reply-guys, please don’t give me your dumb "BuT tHe AiR iS FiLtErEd" excuses. It's still contaminated air before it gets recycled/filtered, and people are still breathing that in and out. It doesn't matter if it gets filtered AFTER that has happened.
@Alice I thought the air out the vents is fresh air, bled from the compressor stage of the engines (usually) and passed through a heat exchanger. A pressurised aircraft stays pressurised by constantly pumping in fresh air and controlling how quickly it's let out again
(I still wear masks in planes btw and usually have a mini HEPA filter blowing air towards me in addition to having the overhead vent on full)
@jackeric Not trying to fight, but it is funny because you're replying to the very comment where I already explained that it doesn't matter if it gets filtered AFTER you've already breathed in the contaminated air.
