I appreciate these wipes and prefer them to most kinds one can purchase. I use them every flight to clean the headrest and remote control (when present).
I hope they dont' go away. I suspect they're loaded on every flight but IME the FA's are getting lazier about offering them or even setting them up for grabs -- I see them only about 50% now. And frequently not available when pre-boarding, but magically appear by Group 2.
