The number of scheduled domestic and international passengers on U.S. airlines dropped 3.4 percent year-over-year in July 2009 to 68.1 million, according to the U.S. Department of Transportation's Bureau of Transportation Statistics.
It was the 16th consecutive month that U.S. airlines saw a decrease in passengers from the prior year.
"The robust economy is an airline's best friend. People pay more for tickets, and they fly more," said Darryl Jenkins, a consultant who runs The Airline Zone, an airline economics Web site. "In a recession, they have less money in their pocket, they fly less often, and they're not willing to pay very much for their tickets."
It has forced airlines to be more frugal when deciding whether to drop, keep or expand existing service or start new service.
Redmond points to studies showing that about half of the passengers within the Yakima area were not flying from the Yakima airport. They are instead opting to fly from Seattle, Portland or Pasco. Redmond and other business officials often use this data to argue that there's an unfilled local market.
But since Yakima is located within driving distance of those airports, some airlines may believe that they are still capturing Yakima passengers and feel less need for bringing new service to the immediate area, Jenkins said.
The Tri-Cities Airport in Pasco is often looked at with envy by local business and airport leaders, as it is one of the few smaller airports in the U.S. that got new air service this year.
This month, the low-cost airline Allegiant Air will begin offering flights to the Phoenix area. And this past summer, United Express began service from the Tri-Cities to San Francisco.
Economic development officials in the Tri-Cities credit the airport's growth to a still-robust economy and a large corporate travel base that includes everyone from Hanford contractors to Lamb Weston officials.
"It takes a good strong business case and I think, frankly, a little bit of luck as far as equipment utilization," said Carl Adrian, president and CEO of the Tri-City Development Council, or TRIDEC.
But the Pasco airport has not been immune to airline cuts.
More than a year ago, the airport lost service to Portland from Horizon Air. More recently, it lost service by Northwest Airlines, which is operated by Delta, to Minneapolis just months after Northwest began offering the service.
That came as a surprise to local officials there, who say passenger loads were in the 90 percent range.
Adrian, of TRIDEC, believes that Delta Air Lines, which had service from the Tri-Cities to Salt Lake City, was in direct competition with the Northwest flight.
"Why would they compete against themselves?" he said.
So while the goal is simple -- showing airlines that they can be financially viable by providing local air service, constantly changing circumstances for the airline industry has created a moving target for airports.
"What makes sense a year ago, doesn't make sense now," said Jim Morasch, director of airports for the Tri-Cities Airport in Pasco.
Yakima airport officials are hoping to find experts who can aim at that moving target -- they're currently taking proposals from consultants who can advise the airport on how to provide the right information that is attractive to airlines.
But given the sluggish economy, airlines may not be ready to talk.
"Airlines are going to be reticent to put new capacity in the market after the disasters of the last two or three years," Jenkins said. "It's not impossible, but it's going to be tough for you to get service."
Redmond knows the airport is facing a long process.
"We have to go into this recognizing that it's going to be very daunting and very challenging," he said. "But I do firmly believe there is a great opportunity for an airline to provide service to other cities and make a reasonable revenue and get more customers into its network."
Beginning April 8, Horizon Air will begin using 74-seater turboprop Q400s for some of its seven daily flights to Seattle.
The Yakima Air Terminal hired a consulting firm to study the demand for expanded air service and eventually help the airport court prospective airlines.

The airport -- the only one served by commercial airlines in Central Oregon -- recorded 188,995 boardings in 2005, up 20.5 percent from 2004.
