An illustrative method provides information to a user on wireless communication coverage along at least one route. A wireless availability server receives a user request for coverage information where the request includes an origination and destination location provided by the user for at least one route. A set of routes connecting the origination and destination locations is determined. A query is made to a database containing wireless coverage data based on the origination and destination locations, and the set of routes. A response to the query contains wireless coverage information along the set of routes. A reply is transmitted to the user responding to the user request where the reply contains the wireless coverage information.
