Because of increased world tensions and terrorist activities, most flight scheduling information is no longer posted on the Internet. One exception is the Joint Operational Support Airlift Center (JOSAC) site, which allows you to check the daily OSA Space-Available Flight schedule and a searchable OSA Flight Schedule. These schedules can only be accessed from a government installation. Also, your DNS server at your base must be configured to do a reverse lookup.
You can also find flight information on an individual location's Facebook page. Check out our Space-A Gateways page for a list of those pages.
