Two airlines have agreed to demands from airline attendants and family groups to filter porn on their in-flight WiFi services. Both American Airlines and Delta announced this week that they would block sites that are considered inappropriate for viewing in public, though problems involving Internet pornography have yet to be reported. "Since the launch of Gogo, American has not experienced any reported incidents of customers viewing inappropriate content via the Gogo service," American Airlines said in a statement issued earlier this week. "However, we believe this is an appropriate measure to take." Gogo is AA's in-flight wireless service offered on select domestic flights between New York, San Francisco, Miami, and Los Angeles. The service is being offered through AA's partner, Aircell, and was just rolled out this August.
