Why Do Some Pilots Fly with Passengers?
In a crowd, the white shirt and black pants signal a pilot. A pilot may be required to board an airliner with passengers for any reason. When such a pilot is in uniform and will be sitting with passengers, there are certain things to watch out for.

The passenger next to him is snoring loudly, and the pilot can’t sleep, use the headset, or eat; all of these are avoided to avoid panic among the passengers. The pilot would frequently have to utilize a spare seat on the plane or fly first class due to most situations.
