Again a travel day, this time an early flight to Brussels with a return to Helsinki on a late flight. Thought to blip something typical of air travel, and caught sight of this sign. The symbol then brought to mind the part "No cigarettes..." of "The Air That I Breathe", and also otherwise the title is in synch with the sign.
