Are you saying that no animals are allowed in the passenger cabin on a flight?

Not more than ten days ago I was on a flight with a little dog that was in a "purse" under the seat. the dog looked like shaggy version of P Hilton's foo foo. When I was in the Atlanta airport a women walked by with a Siamese cat on her shoulder. She was obviously traveling.

It is a good point about pets allowed, peanuts not. Not that I'm really sad about not getting peanuts. I do understand the allergy issues though.
