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

Humans are difficult beasts. 

Their emotions drive them. 

Can we call selfishness an emotion? 

I only ask because one airline has finally decided to do something about all those alleged emotional support animals that people take on planes.

Animals that many would describe as mere household pets.

And other passengers would describe as nuisances. 

Delta has listened.

It's instituting new rules because, it says, there's "a lack of regulation that has led to serious safety risks involving untrained animals in flight."

Last year, indeed, a dog bit a man on a Delta flight. The man suffered serious facial injuries.

So Delta's new rules at least attempt to avoid another such situation.

From March 1, the airline will require that "all customers traveling with a service or support animal show proof of health or vaccinations 48 hours in advance. In addition to the current requirement of a letter prepared and signed by a doctor or licensed mental health professional, those with psychiatric service animals and emotional support animals will also need to provide a signed document confirming that their animal can behave to prevent untrained, sometimes aggressive household pets from traveling without a kennel in the cabin."

Some will worry that this is like getting a doctor's certificate for your bone spurs. You'll always find a friendly one that will sign whatever you want.

The proof will surely lie in whether there will be fewer animal-related incidents. 

The airline says it's seen an 86 percent increase in bad animal behavior on flights. 

"In 2017, Delta employees reported increased acts of aggression (barking, growling, lunging and biting) from service and support animals, behavior not typically seen in these animals when properly trained and working," the airline insists.

It says there have been far more incidents of urination and defecation. 

One driver of this new approach is to protect genuine service animals from being attacked by unruly pets.

"Customers have attempted to fly with comfort turkeys, gliding possums known as sugar gliders, snakes, spiders and more," it says. 

I've never seen a spider give emotional support, have you?

Oh, wait. There was Robert the Bruce, but that was a very long time ago.

There are so many other elements that make flying uncomfortable. 

At least Delta is trying to curb one.
