BURBANK -- A bid to impose a curfew on flights at Bob Hope Airport in Burbank just didn't fly with federal officials.

The Federal Aviation Administration announced on Monday that it has rejected a request to ban nighttime flights at the airport.

The agency said in a letter that such action "was not reasonable" and would "create an undue burden on commerce" as well as negatively effect the national air transportation system.

The Burbank-Glendale-Pasadena Airport Authority proposed a nightly curfew from 10 p.m. to 6:59 a.m., except in emergencies. Residents and local officials have been fighting for decades to reduce airport noise in the area.

In 1973, the Supreme Court even weighed in, striking down a Burbank ordinance banning overnight takeoffs from the airport, then called the Hollywood-Burbank Airport.

The FAA says there are other alternatives available for reducing noise, such as soundproofing homes near the airport.

Fed Ex, United Parcel Service and other cargo companies and trade groups objected to the curfew, saying it would harm the economy just as it was showing signs of recovery. Opponents also argued that a curfew at Bob Hope Airport would have a ripple effect on the national air transportation system, leading other airports to seek to restrict flights.

The FAA says the airport authority can challenge the decision in federal court.

Airport officials say they will continue efforts to reduce noise in neighboring areas.
