Never Share a Blanket
Flight attendant here!
My old airline was a Delta connection and we only had Dash-8 planes, so I was the only flight attendant on board. One flight, while I was picking up trash, I saw two gentlemen, um, being intimate under one of blankets that we provide on the plane for everyone to use. I didn’t say anything because the flight wasn’t full and they weren’t being obnoxious.
At the end of the flight I see them fold up that same blanket and as they went to put it back in the overhead bin I hollered out, “Nope! That blanket is yours now! We don’t want it.” Needless to say they hurried off the plane when we landed.
Also never use a blanket that didn’t come packaged.
