Air Carrier Access Act Technical Assistance Manual (2005)

You shall not exclude a passenger with a disability from any seat in an exit or other row solely on the basis of his or her disability except to comply with FAA safety rules. FAA safety rules establish criteria that must be met in order for a passenger to occupy a seat in the emergency exit rows. [14 CFR 121.585] If a passenger with a disability meets these FAA criteria, he or she must be allowed to sit in an emergency exit row. As with any other passenger, you must look at the individual passenger with a disability and reasonably assess whether he or she meets FAA criteria for exit-row seating. [Sec. 382.37(a)]
