Passenger traffic at Salt Lake International Airport continues to decline.

The volume of travelers arriving, departing or making connections at the airport dropped 7 percent in February compared to the same month last year, according to statistics released this week. Passenger traffic was down 7.4 percent in January.Last year, the airport experienced a drop in annual passenger volume for the first time in 16 years.

Airport and airline officials attribute the decline to a strong economy that is keeping ticket prices up. Fewer bargain rates are being offered. But most travelers, particularly business people, are still booking flights and airlines, in general, are making more money.

The Salt Lake City Airport Authority has responded to years of unprecedented growth in passenger volume with a 20-year, $1.7 billion expansion project, and those plans are unlikely to change.
