When it’s all said and done, 2013 will be a banner year for the Casper-Natrona County International Airport.

Roughly 100,000 departures are expected by the end of December – a milestone that hasn't been reached since 1987.

However, airport officials say business can still be better. Airport manager Glenn Januska says Casper loses about 40,000 passengers annually to Denver.

Januska says the focus in 2014 will be to stop the “leakage.”

“That’s our focus, it’s been our focus, it will continue to be our focus,” Januska said. “In terms of fares, and frequency of service, and size of aircraft, and markets, we’re going to continue to work with the airlines and really try to capture some of that leakage back.”

With one month remaining, 90,685 passengers have flown out of Casper in 2013. Just under 90,000 passengers flew out of Casper in all of 2012.

Januska says the airport has seen a 13.5 percent year-to-date increase in departing passengers.
