Final answer:
At some airports, passengers have the option to submit alternative forms instead of filling out the blue form. These forms confirm the health, behavior, and training of the animal and can be required by airlines either before travel or at the departure gate.
Step-by-step explanation:
At some airports, an alternative to filling out the blue form is submitting forms attesting to the animal's health, behavior, and training. These forms can be required by the airlines either 48 hours before the travel or at the departure gate. For passengers with a Seeing Eye-certified or other officially trained dog, providing these forms is not an issue.
