Los Angeles' top city administrator, Miguel Santana, last month urged Los Angeles and Ontario officials to begin negotiations.
Santana's move was backed by a Los Angeles City Council subcommittee.
"I'm fairly sure they are going to be in support of the subcommittee," said Ontario Councilman Alan Wapner, who is the city's liaison on the issue.
Wapner said he plans to attend the meeting and address the council in case members have any questions.
From there, Wapner said he expects Ontario City Manager Chris Hughes to begin negotiations with officials from Los Angeles World Airports, which manages and operates ONT.
Last month, Ontario officials created the multijurisdictional agency, the Ontario International Airport Authority, to prepare for the possible transfer. The agency would be in charge of the operations.
Wapner said the first meeting for the authority has been set for Monday.
Since Santana's recommendation, LAWA has been forthcoming about discussing negotiations with Ontario officials.
For the past three years, Ontario officials have waged a battle against the agency that oversees the airport. They said the agency hasn't done enough to attract airlines to Ontario.
The Los Angeles City Council meets at 10 a.m. Wednesday.
