Just wanted to file this and say that if a baby cries and screams on a flight; it will not be removed from the flight;that is what customer service stated to my wife; if a puppy yelps, you will be removed from the flight and the ticketing agent will threaten to call the police and have you thrown in jail, and you will be abandoned at the gate and customer service will say" Sorry, but there is nothing we can do"; even if your in a different city, your luggage is on the flight home and you do not know anybody in the dump off point. South West was completely unprofessional, un-caring. I paid $75.00 for the additional ticket: do we pay $75.00 for a carry on, like a computer bag which fits underneath the seat? Or puppy weighs 9 lbs. The air lines completely dropped the ball here: My wife is stranded in LV with her puppy and the flight has landed in Reno without my wife. Their attitude was appalling and unforgiving.
