6. Using the toilet right before take-off
When nature calls, you have to handle it. Everyone has the chance to visit the bathroom at the airport as many times as they need as well as during the boarding period and even after take-off on the plane. Even though there are no specific rules preventing you from using the toilet right before take-off, it’s really dangerous for you to do your business while the plane is on the taxiway. The pilot cannot legally start the plane or take off with someone in the bathroom, so using it during this time can cause delays during the flight.
