Final answer:
Pet owners cannot access airplane cabins with their pets without proper documentation for service animals, according to new regulations designed to prevent exploitation of previous loopholes.
Step-by-step explanation:
Pet owners are not allowed access to specific areas of practice, such as airplane cabins, without appropriate documentation for service animals, as per new regulations developed by various stakeholders. These restrictions have been put in place to close loopholes previously exploited by some pet owners who wished to avoid using a pet carrier or paying a pet fee. The regulations aim to ensure that those with a genuine need for service animals, including psychiatric service animals, can still travel with their documented and trained companions while curbing the misuse of the system tied to emotional support animals.
