I have flown with frogs a dozen or more times as have many others. The prohibition against carrying frogs is airline policy, not homeland security policy. Therefore, you USUALLY don't have any trouble getting through security. I have never had any problems. I have a special carry-on duffle that I pack the frogs in. A couple of times of seen the screeners smile and shake their heads as the bag went through the X-ray machine.
Why airlines allow yappy dogs, yowly cats, and even squawking birds on their planes but not oderless and quiet frogs is beyond me. But I've never had an incident.
