The Cleanliness Of In-Flight Blankets & Pillows
The worst, most unsanitary thing in a plane, research has concluded, is the tray table. They rarely get wiped down, and people place their hands, heads, food, and belongings on them. Still, a close second would be the inflight pillows and blankets.
While they are given wrapped in plastic, you might be surprised to learn that they usually aren’t fresh. In fact, blankets and pillows are usually collected at the end of flights, folded, repackaged, and given to the next round of passengers. If you’re absolutely set on sleeping on clean pillows, though, don’t despair: early morning flights usually have clean(er) sets.
