DiCaprio's representatives told UsMagazine.com the "Titanic," "The Aviator" and "Inception" star was on his way to attend a four-day meeting in St. Petersburg, led by Russian leader Vladimir Putin, to discuss ways to prevent the extinction of tigers.
"(DiCaprio) wishes to commend the actions of the pilot and flight crew in bringing the plane to a safe landing," the actor's publicist said in a statement issued to UsMagazine.com.
