Airline passengers can already get online 30,000 feet over Oklahoma. Soon U.S. airlines will offer Internet connections over the ocean, too.
United, Delta, and American — the nation's three biggest airlines — said Wednesday that they're within weeks of having their first international flights with Internet service.
It's fairly common for passengers to check email and update Facebook while flying over the U.S. But the air-to-ground signal used by those planes won't work over the ocean. So airlines are installing satellite-based systems to solve that problem.
