Here are more details on restrictions to her use of a military jet:

The letter from the Pentagon yesterday cites specific U.S. Code that government policy does not include the routine use of military aircraft for the speaker of the House.
“Nonstop service is not guaranteed, meaning she’s getting Hastert’s plane and nothing bigger,” the congressional source said, referring to the commuter jet Mr. Hastert began using for security reasons after the September 11 terrorist attacks.
But the administration official said Mrs. Pelosi “wanted to be able to fly between Washington and the West Coast nonstop.”
The letter leaves open the possibility that Mrs. Pelosi may get a larger plane that does not require refueling if one happens to be available in the 89th Airlift Wing at Andrews Air Force Base. But, generally, the larger military passenger jets are in high demand, especially due to the Iraq war.
In addition, the letter stipulates that the Air Force will only fly her between Washington and her San Francisco district and places limits on who can travel with her.

“Non-governmental personnel, i.e. political supporters and contributors, may not fly,” the congressional source said yesterday, paraphrasing the letter sent to Mrs. Pelosi. “The plane may not ferry her to any political events and other members may only accompany her after approval by the House ethics committee, which means Republicans would have to OK it.”
Immediate family members who fly with her must pay the U.S. Treasury for the flight.

Aren’t you glad that’s settled!
