Air Carrier Access Act Technical Assistance Manual (2005)

Service Animals

It is not required under the law to provide advance notice if you are traveling with a service animal. However, in order to guarantee your seat assignment, you should be aware that, depending on whether the carrier provides advance seat assignments and the type of seating method it uses, it may have a policy requiring passengers with a disability (i) to request a particular seat assignment 24 hours in advance of the departure of the flight or (ii) to check in at least an hour before the departure of the flight. Carriers are obligated to make a good faith effort to accommodate you and your service animal regardless of whether you comply with the carrier’s advance seat assignment policy and/or advance check-in requirement. Keep in mind that requesting your seat assignment well in advance of the flight may permit you to secure the specific seat assignment you would like with the least amount of waiting, inconvenience, or hassle to you.
