EVERETT — The cities of Edmonds and Mukilteo and other foes of commercial air service at Paine Field have filed a notice to fight the decision in federal court.

The (Everett) Herald reports the notice filed with the federal court of appeals could lead to an April hearing.

The Federal Aviation Administration determined in December that flights proposed by Allegiant Air and Horizon Air at the airport would not significantly increase noise, traffic or air pollution in nearby communities.

The county is starting to plan for a terminal. Though most county officials oppose commercial flights at Paine Field, the county is required to provide space to airlines if it wants to continue receiving federal money for the airport.
