The airlines' applications will be approved "as soon as possible," said Paul Takemoto, a spokesman for the F.A.A. "We are interested in anything that might improve onboard security.
The agreement, announced last month, aroused residents who had opposed the airline's application for space at the airport last summer.
But some industry specialists say the filing will probably strengthen the airline's application because it will include the cost cuts that the government has been seeking.
Despite its cash squeeze, United is reluctant to file for bankruptcy protection as long as the federal Air Transportation Stabilization Board is considering the airline's application for $1.8 billion in federal loan guarantees, the executive close to the negotiations said.
Mr. Parker stressed that the airline's application relied on more conservative assumptions about the industry's recovery than are being used by Wall Street to demonstrate its ability to repay the loans.
But the matter set off a political storm, given Mr. Snow's intervention, Mr. Hastert's political power and the fact that the White House had not previously played a role in any airline's application.
The ministry rejected in December 1991 the airline's application for flying to Stockholm and Copenhagen.
In December, the airline filed applications with the Department of Justice (DOJ) to fly from Houston to four popular Mexican vacation spots: Cancun, Los Cabos, Mexico City, and Puerto Vallarta, as well as Belize City, Belize, and San Jose, Costa Rica.
The airline sent an application to register the Caravelle in April, but the application was canceled later in the month, and the aircraft was subsequently registered in Sweden.
However, the loan board has suggested that the airline trim its application by about $100 million and seek the rest from other lenders, people involved in the discussions said.
