At the request of the U.S. Secret Service, the FAA is restricting air traffic Saturday evening within 1.5 miles of Rhinebeck, New York, the expected site of the much-anticipated wedding. Air traffic over 2,000 feet - including all commercial flights - will not be interrupted.
The Secret Service requested the flight restrictions for security reasons only, the FAA said. In this instance, the notice says it is for "VIP movements."
It is common for the FAA to grant temporary flight restrictions - or TFRs - to increase security where government VIPs are moving or gathering. The number of security-related TFRs has jumped since the 2001 terrorist attacks.
And while the guest list for the Clinton-Mezvinsky wedding has not been announced, at least two prominent participants will clearly be in attendance - Secretary of State Hillary Rodham Clinton and former President Clinton.
The restrictions on low-level flights will last from 3 p.m. Saturday until 3:30 a.m. Sunday.
