Not all airlines “invest” in using good quality toilet paper on airplanes. Therefore, there are many types of paper of poor quality that melt immediately when soaked in water. Therefore, you can use the tissue paper you prepare instead of using the toilet paper available in the airplane toilet.

In addition, toilet paper in airplane toilets is often placed low, so it is easily dirty due to plane shaking, other people using the toilet, etc., so it is not guaranteed to be clean for you to use.
