In its own seat?
Because if a dog is over, say, 30#, I say it must have its own seat.
This stuff is well beyond ridiculous.
No. The German Shepherd was sprawled out on the floor under my feet. On the flight back I only had to contend with a 225 pound mother with a 3 month old baby in the middle seat next to me. The crying, pooping and breast feeding seemed mild compared to my previous flight.
