Q. I have a 6 pound, very quiet, chihuahua  that we would like to take with us when we fly. Can he go as carry-on luggage in his own tiny carrier which would fit under a seat, without being charged extra? If not, what is the difference between a quiet behaved pet verses a child sitting on a parent's lap?

A, Unfortunately, the airlines don't lower fares for good behavior. You'lll end up paying as much as $80 each way for your pet, depending on the airline. And you bring up a very good point about the lap child. Perhaps airlines should add a surchage at the end of the flight if a lap child has been rowdy!
