I Have seen it here...to my chagrin. I was flying delta last month a the lady next to me had a dog in the bag under the seat. She of course had to take it out and hold it on her lap. The flight attendent had her EVentially put it back in the bag. I'm scared of dogs (bitten by german shepard at age two). Horrible experience. People are so inconsiderate. What if instead of a dog you changed the pet involved to Rat, Snake,Spider,Weasel,Skunk etc... You wouldn't feel the same way would you? And of course last night the guy next to me on CO had a dog in a bag. Thereforre the correct answer is... sure you get to bring your dog on a flight as long as you sit next to cigarman
