CO allows 4 pets per cabin in Y and 1 in F. Both CO and DL state that one pet per person is the rule. Seems like I have seen one airline that allows more than one pet per if they fit comfortably in the same kennel.....2 kittens perhaps?
What happened to the lady is terrible. I would be more apt to demand to be moved over the ladies size than the pets.......although having them out during flt. is not acceptable.
