Right now you can qualify to have an emotional support animal, on line for 79 bucks. No actual visit to a doctor. Imagine if you really had to see a doctor, pay what that might cost and renew it (with cost) on an annual basis. That would probably weed out a vast majority of the BS. Sad for those who really do need an emotional support animal. One of the last emotional support dogs I had on one of my flights tried to bite one of the FAs.
