Tucson International Airport is reporting a 5 percent increase in air travel so far this year. As of the end of last month, the airport recorded 2.4 million passengers, marking 15 straight months of increases.
The Tucson Airport Authority says airlines are responding to passenger demand at TIA by upgrading to larger aircraft and adding new flights, including Alaska Airlines' nonstop service to San Jose, which launched in August.
Starting in December, Sun Country Airlines will begin offering service with three weekly nonstop flights between Tucson and Minneapolis/St. Paul.
Other airlines also are boosting flight service and aircraft in and out of Tucson.
