Since commercial airlines will probably never allow smoking henceforth, it seems wasteful to have the “no-smoking” light next to the “fasten seatbelts” light. While the latter is a condition which will change over a flight, the former condition is constant; unlike, say, the usage of portable electronic devices. So, why not make that a light instead?

As I discovered on a flight last week, however, apparently USAirways beat me to the patent office. Moral victory, I suppose.
