Airline passenger traffic at Tucson International Airport was up more than 5 percent this year through September, to 2.4 million passengers, marking year-over-year increases for 15 consecutive months, the Tucson Airport Authority said.

The Airport Authority said airlines are responding to passenger demand at TIA by “upgauging” to larger aircraft and new flights, including Alaska Airlines’ nonstop service to San Jose, which launched in August.

In December, TIA will welcome its newest carrier, Sun Country Airlines, with nonstop flights from Minneapolis/St. Paul.
