If you're planning a flight longer than eight hours, Delta Air Lines says you can't bring an emotional-support animal with you. The rules for pups are getting tighter, too. Neither support animals nor trained service animals will be allowed on any Delta flights if they are under 4 months old. Delta says the changes take effect Dec. 18. The airline says exceptions will be made until Feb. 1 for customers who already bought a ticket and asked to bring a support animal, the AP reports.
Airlines are tightening rules on animals, saying their numbers have skyrocketed and some have relieved themselves or bitten other animals—and in one case, a Delta passenger. People who fill out the forms to travel with a support animal avoid pet-carriage fees. "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," says Delta exec John Laughter. (Earlier this year, United Airlines rejected an emotional support peacock.)
