The Lewiston-Nez Perce County Regional Airport and the Idaho Falls Regional Airport are among the facilities on a list of 149 slated for closure around the country.
Both are scheduled to lose federal funding on May 5. Officials involved with those airports met earlier this week to consider options.
The other Idaho airports on the Federal Aviation Administration list are the Pocatello Regional Airport and Friedman Memorial Airport in Hailey. Officials with the Friedman airport said last week they would seek an injunction to prevent the federal government from shutting down the tower, but no date for legal action was set.
Craig Davis, airport director at the Idaho Falls airport, said the facility will shift money from maintenance and other areas to keep the tower operating through Oct. 1.
"We might be able to put off fixing a cracked ceiling or a ramp for six months to shift (money) over and pay for the tower operations through the end of the fiscal year," Davis said. "After, we'll look to revise the (entire city) budget to include the tower."
He said the city is committed to paying for tower operations starting Oct. 1. However, Councilwoman Sharon Parry said the council hasn't had that discussion yet, though she supports funding the tower.
Davis said it costs about $425,000 annually to run the tower, paid for currently by the FAA. He said the city is looking at spending about $300,000 annually, which would mean cutting the hours of the tower.
"We need to come to understand what measure of safety we are buying for potentially $300,000," Parry said. "Those questions will need to be asked and answered as we move forward. I don't have an inkling where the council will land on it."
Davis said he'll push for finding a way for local money to keep the tower operating.
"We are bound to provide safety," Davis said. "That's why we are choosing to self-fund the tower."
In northern Idaho at the Lewiston airport, airport manager Robin Turner estimated it would cost $750,000 annually for local entities to take over tower operations.
At a meeting Tuesday, officials considered ways to keep the tower open. An FAA spokesman during a teleconference call said the agency would enter into an agreement to maintain all the electronic systems, but local entities would have to pay the bill.
Local officials agreed to send a letter to the FAA complaining about the closure.
The FAA is under orders to trim hundreds of millions of dollars from its budget. Last month, it released the list of control towers that would be closed.
The closures will not force any of the airports to shut down, but pilots will have to coordinate takeoffs and landings over a shared radio frequency with no help from ground controllers.
Airlines serving rural Idaho said they were accustomed to flying into airports without control towers and would continue their services.
