SOOOOOOOOO TRUE!
The last enjoyable flight I had was one of the last smoking flights between Sydney and LA at Christmas 1994. By then there were only six rows at the back of economy for smokers, and those of us who got those seats got them five hours before the flight departed.
In the Christmas spirit, we shared our smoking seats with the other half of the 747 who smoked. This meant that at any given time, there were 20 or so people standing at the rear of the aircraft. The sh*tty young United hostie chucked a wobbly, and the senior hostie (from the fine age of flying) finally moved her to the forward cabin and let us continue.
Since that time, flying has become more like a Greyhound bus with wings. Screaming babies, stinky people, and mad Arabs.
Actually, since smoking was banned, there are a lot fewer "stinky" people...
