Oct 1, 2009 FRNTQ Frontier Airlines Holdings, Inc. Common Stock Pink Quote Deleted Plan of Bankruptcy effective immediately
Symbol has been deleted so this will no longer trade again. It may come back at a later date but will most likely do so under a new ticker/cusip and with new share organization.
