The US Department of Transportation says that airlines don't have to let support animals into the cabin if they're too large, heavy, disruptive, or threatening to the crew and passengers.
Emotional support animals are not considered service animals under the ADA, so they have different laws to govern them. Starting March 1, the airline will require 48-hour notice, an "enhanced" letter from a mental health professional, confirmation that the animal has been trained to behave properly in public, and an acknowledgment of responsibility for the animal's behavior.
