Delta Air Lines bans emotional support animals

Also, Southwest is already pretty strict when it comes to emotional support animals.

the difference is that up until now, an "emotional support animal", could be carried on board without being in carrier, and sit on the persons lap if the size was small enough..an ordinary traveller who just wanted to take their cat,or their small dog who would fit into a carry on sized kennel to fit under a seat,had to pay for the privilege..its a good move because so many people did abuse the "emotional support" clause..a "service animal",which is about 99% of the time a dog like a labrador or golden retriever,is always well trained,stays only with the owner,must sit at the feet of the owner while on board,wear a service vest,and are not to be petted nor touched unless the owner says its ok..i worked with many and never had an issue, as opposed to people with a turtle or a bird or some other such who insisted they were for emotional support!

Huh? All of the big 3 airlines and some others I think have banned emotional support animals.
