@KrauthBen @sqL_handLe @CT_Bergstrom You're overly focused on the plane in flight itself, ignoring ground time, airports, shuttle busses, local transit, etc.
And it's not a "cloth mask mandate". It's a mask mandate. When required to wear any mask, many wear something better than a cloth mask (at least surgical).
@KrauthBen@sqL_handLe@CT_Bergstrom你过度关注飞行中的飞机本身，忽略了地面时间、机场、穿梭巴士、当地交通等。
而且这不是“布面任务”。这是一个面具任务。当需要戴口罩时，许多人会戴上比布口罩更好的口罩（至少是外科口罩）。
