Frontier Fifth Mexico Destination

DENVER, Colo (Aug. 4, 2003) - Frontier Airlines (Nasdaq: FRNT) today announced its intention to add Ixtapa/Zihuatanejo as its next Mexico destination. The Company has filed an application with the U.S. Department of Transportation (DOT) for authorization to serve Ixtapa/Zihuatanejo, Mexico from its Denver International Airport (DEN) hub. The airline already serves, or plans to serve, four cities in Mexico: Puerto Vallarta, Los Cabos, Cancun and Mazatlan.

“Ixtapa/Zihuatanejo is another key destination for Frontier, and it is our intent that when customers think of traveling to Mexico for vacation or business, they automatically think ‘Frontier’,” said Frontier Vice President of Marketing and Planning, Sean Menke.

If granted authority, the Company plans to begin operating the service in the first calendar quarter of 2004.
