Illuminated no-smoking seat signs
Why do they still have those signs at every seat in newer planes? Are their any commercial flights that still allow smoking at all? Why not have a few permanent signs, or a few pasted decals (like in trains or buses)? Paired up with the Seatbelt sign makes one think they'd want to switch it off sometime....
Does the crew even have a switch to turn that sign off any more? Wouldn't it make wiring easier, costs lower and more importantly reduce cabin clutter to get rid of these per-seat, lighted, no-smoking signs?
Maybe they made sense in the 70's but most public places are already smoking free so people must be more conditioned not to light up, I hope?
