As soon as you enter the airplane, find your seat and have a package of anti-bacterial wipes handy in your purse or carry on. Immediately wipe the tray button, tray, both sides, the video screen, and controls, and the back of the seat in front of you, the safety instructions card and whatever else is in front of you with a wipe.
Wipe the arms of the chair on both sides and bottom and the reclining button. Wipe the upper buttons, lights, call, etc. If you are on the window seat, wipe the window and its surroundings. Wipe the headrest. Wipe everything with a wipe that you know someone else has touched. Use more than one wipe for this cleaning. Ask your seat partners if they would like a wipe. Hopefully, they will think it’s a healthy idea too.
