Leonardo DiCaprio was able to make his $1 million donation for tiger conservation Tuesday after being delayed by an air crisis.
“En route to attend the Tiger Summit in St. Petersburg, Leonardo DiCaprio was one of the passengers aboard Delta Flight 30,” a spokesman for the actor said. “He wishes to commend the actions of the pilot and flight crew in bringing the plane to a safe landing.”
The flight was forced to make an emergency landing at John F. Kennedy Airport in New York after blowing an engine and dumping fuel.
When the crisis in the air was over, “Leo signed a bunch of autographs for the crew and the passengers,” a source tells PEOPLE. “Everyone is fine.”
DiCaprio, 36, is joining heads of government from the 13 tiger range countries in St. Petersburg, Russia, for a first-ever summit to save tigers. Hosted by Russian Prime Minister Vladimir Putin, the summit’s aim is to save tigers from extinction. DiCaprio’s $1 million donation to the World Wildlife Fund will aid urgent tiger conservation efforts.
“He is doing great,” a DiCaprio source says. “Happy to make it to St. Petersburg safe admittedly a little late.”
