The maps purport to help when you get the error message:
No flights were found. Try expanding your search by selecting alternate dates, class of service, airports, number of stops or including more carriers. Please check Where We Fly for airports we serve.
Though I am sure that aa.com could equally well check the list and tell you if AA and/or its codeshare partners served the airport!
