Frontier facing $380,000 fine

WASHINGTON — Federal regulators are proposing a $380,000 civil penalty against Frontier Airlines for using the wrong sign to guide passengers toward one of the emergency exits on its plane s.

The Federal Aviation Administration said today that Frontier operated about 900 flights without the right signs.

The FAA says that in 2008 and 2009, Frontier reconfigured the cabins on some of its Airbus A318s and A319s to that two aisles could access the emergency exits over the wings. But the signs didn 't show the new layout.

Frontier is owned by Indianapolis-based Republic Airways Holdings.

Spokesman Carlo Bertolini says the company does not believe passenger safety was affected, but that Frontier will use the incident to improve its compliance programs.
