The ownership saga for ONT between the cities of Ontario and Los Angeles included everything from a congressional hearing to the start of negotiation discussions.
After engaging in talks for three years, Ontario officials started 2012 by launching a social-media campaign asking the public to help "Set ONTario Free."
And by the end of the year, the city was successful in gaining the attention of L.A. officials, who agreed to begin discussions for the transfer of control.
The report, released in late September by L.A.'s top administrator, was a glimmer of hope for Ontario officials who wanted a chance to revive the ailing airport.
"The action that has been brought to regain the airport by the city of Ontario, and all of our friends, is historic. A movement like this has never taken place to this degree," Councilman Jim Bowman said.
• City officials launch a public-relations effort - SetOntarioFree.com - to sway Los Angeles voters in their quest to regain control of ONT. Included in their efforts is a poll that the city says shows a majority of voters support transfer of ONT to Ontario from Los Angeles.
• Two Los Angeles councilmen on Jan. 24 call for a study of how to return ONT to Ontario's control.
• Federal Aviation Administration officials express to two Inland Empire politicians that there is little they can do to improve operations at ONT, despite concerns about the decline in traffic. Reps. Jerry Lewis, R-Redlands, and Ken Calvert, R-Riverside, meet with FAA officials as a follow-up to a letter they sent to Secretary of Transportation Ray LaHood raising their concerns about operations at ONT.
• Los Angeles Mayor Antonio Villaraigosa says he would not approve the sale of ONT until the real estate market bounces back. He cites his financial obligation to taxpayers as a reason.
• Ontario officials get their biggest endorsement in efforts for local control. After hearing about the dismal conditions plaguing ONT, Los Angeles City Council's Trade, Commerce and Tourism committee directs the city's administrative officer to begin analyzing Ontario's proposal.
• Baseball icon Tommy Lasorda becomes the city's newest champion in its quest to reclaim control of the airport.

• Allegiant Air becomes the first airline to publicly acknowledge LAWA's high costs at ONT. The low-cost carrier suspends flights between Los Angeles and three northern cities, citing a shortage of space at Los Angeles International Airport, but says the costs of operating out of ONT instead would be prohibitive.
• Despite the decline in passenger traffic through August, air cargo at ONT is up by about 15 percent.
• City officials announce the formation of a Joint Powers Agreement with San Bernardino County to create the Ontario International Airport Authority. Governed by a five-member commission, the focus of the authority - if Ontario gained control of the airport - would be to operate and grow the airport.

• A report released by LAWA details the value of the Ontario airport, ranging from $243 million to $605 million, based on several factors. The exact figure depends on how much the airport would bring in in the next 50 years.
• Months after it was expected, Miguel Santana, Los Angeles' top administrator, says his city should decline Ontario's offer but begin negotiations with Ontario officials for the potential transfer. The 107-page document was hailed by Ontario officials as a step forward.
• The Trade, Commerce and Tourism committee agrees to open discussions for transferring control of the airport, and asks that a progress report be given every 90 days on negotiations.
