...Does anyone know if
INS is still used on civilian airliners, particularly on overseas
flights?


Trans-oceanic or polar flights are about the only place you'd need one,
anyway. When I last flew (mid-90s) my employer, a non-sked freight hauler,
was looking into converting from INS to GPS. I'm guessing there aren't many
INSs left, at least on US registered craft.
