Hundreds of private planes have descended on Sun Valley for this year's 'summer camp for billionaires'

The biggest names in tech and media have arrived in Sun Valley, Idaho for the annual conference hosted by investment bank Allen & Co. 

The event is known as "billionaire's summer camp" for a reason - Elon Musk, Rupert Murdoch, Barry Diller, Jeff Bezos, Jack Dorsey, and Sheryl Sandberg have already made their arrival at the Sun Valley Resort.  

And their preferred mode of transportation? Private plane.

The event is considered one of the year's biggest for private jets, with officials at Friedman Memorial Airport expecting more than 200 jets to land on Tuesday alone, according to CNBC.

Airport officials warned of possible delays in a letter to flight operators in June. 

"The most arrival-congested window at SUN, during this event, is between the hours of 12:00 pm and 6:00 pm (lcl) on these days," Airport Manager Rick Baird wrote. "Scheduling arrivals prior to or after this period will likely afford less inconvenient delay."

A record of arrivals we found on FlightStats show that a number of private jets chartered through NetJets and XOJet landed at Friedman Tuesday evening. The city listed on the left-hand side is the flight's point of origin. 

NetJets is a subsidiary of Berkshire Hathaway that allows users to partially own or rent private planes. XOJet runs a similar operation. 

More private planes continued to arrive from San Jose and Seattle Wednesday morning. 

"It all depends on the size of the aircraft," Baird told CNBC. "If there are a lot more large corporate jets, then we could run out of room."

Baird said that he expects Friday and Saturday to be the busiest day for private jet traffic. The conference's last presentation will wrap up on Saturday afternoon.
