Business in Brief: United joins Delta in tightening rules for comfort animals
In this Saturday, April 1, 2017, file photo, a service dog named Orlando rests on the foot of its trainer, John Reddan, while sitting inside a United Airlines plane at Newark Liberty International Airport during a training exercise, in Newark, N.J. United Airlines wants to see more paperwork before passengers fly with an emotional-support animal. United says the changes won't affect owners of legitimate service animals with special training.
