One of the first rules is to never use the tray table as baby changing station. Just don’t. This is unsanitary as tray tables are not cleaned between flights and in a few hours someone will be using that same table to have their lunch, or even just rest their hands or items on. It’s also inconsiderate to your seat-mate. Most airplane bathrooms have a changing table. If not, wack a cloth or blanket (for sanitary reasons) over the closed toilet seat as a makeshift table. Here are the dos and don’ts for passengers on airplanes.
Have you ever done any of these airplane don’t dos?
