13.6km is 44,619ft.
So nearly every time one flies commercial, yes, since cruising altitude is between 30,000 and 40,000 feet. I think a large triple-star system would be quite visible at that point.

I imagine if you were 13.6 km from a star you would either burn up or fall into the star’s gravity well.
