Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek. 

It's become a very contentious issue.

People have taken liberties and airlines are beginning to lose their patience.

Many passengers are, too.

Too many people think they can bring their pets on the plane and claim they're emotional support animals.

Airlines have begun to take steps to curb the practice. I have a feeling the lady with the emotionally supportive peacock took things a little too far and inspired airlines to act.

Now, however, Delta Air Lines is taking its policy a lot further.

It announced today that it's banning all service and support animals under four months of age. 

Yes, puppies and kittens, you may have to fly private.

This new policy takes effect on December 18. 

Delta says the CDC's rabies vaccination requirements are behind the move. I suspect the airline's cleaners might be behind the move, too.

Banning puppies and kittens, though, isn't the only vast change. The airline is also banning all emotional support animals from flights over 8 hours.

Which is surely going to upset one or two passengers who want to take their puppies or mice to Moscow from, say, Atlanta.

The airline offered this statement, reported by the Atlanta Business Chronicle

These updates support Delta's commitment to safety and also protect the rights of customers with documented needs -- such as veterans with disabilities -- to travel with trained service and support animals.

I asked Delta why it had chosen 8 hours as its cut-off point and will update, should I hear.

I can imagine some passengers would prefer many supposed emotional support animals to be banned from flights over 8 minutes, such are the controversies that sometimes ensue.

Sample: the Delta passenger who said he was bitten by another passenger's dog on a flight from Atlanta to San Diego.

There was blood.

Please, therefore, remember if you're flying during the Holiday period: a puppy is not just for Christmas.

And it's just not for Delta.
