Tucson International Airport officially opens its new C Gates this week. The airport is seeking additional low-cost carriers amid an effort to boost tourism to the southern Arizona city.

Allegiant Airlines will be the first carrier to use the gates, which are in a separate facility about 300 feet from the main terminal.  Tucson Mayor Jonathan Rothschild says the new terminal will help attract new low-cost airlines, providing more destinations for city residents and increasing tourism.

The Tucson Airport Authority said it is already looking at the possibility of expanding the C Gates facility in the future.
