Boise versus Spokane Airport Passenger Trends

People did not believe me when I said that Spokane International Airport handled fewer passengers in 2009 than it did in 1996. They also did not believe me when I said that Boise Airport had seen a net increase over that time. Here then is the actual data and a chart to make the point clear – this is based on data provided by each airport.

Boise remains up in total passengers over the period 1996 to 2009 while Spokane had more passengers in 1996 than it does in 2009. The immediate downturn is due to the economy but that does not explain Spokane’s drop to below 1996 levels. According to the Spokane Airport data, 2010 is running 1.3% above 2009 levels, which means that 2010 would also be below 1996 traffic levels.

The choice of starting years was determined solely by Boise only providing data back to 1996. Data on Spokane is available back to 1990. The choice of Boise versus Spokane is based on each city’s selection of the other as a “comparable city” for comparing each cities relative economic performance.

It is interesting that Boise Airport has produced roughly the same number of air passengers as has Spokane International Airport. Spokane County has an estimated 468,684 residents (US Census official estimate for 2009) versus 384,656 for Ada County, Idaho (home of Boise).  This difference could be do to the much higher incomes of the Boise area versus the very low incomes of Spokane.  Spokane residents may not be able to afford to fly as much as Boise residents. Other factors could be related to the mix of industry in each area, or perhaps travelers come from a wide area around Boise to use their airport.

Notes

The Boise data was difficult to transcribe. Some was only provided in PDF format and had to be entered by hand. All is provided only in monthly values. For most of the data, table formats changed from year to year and required much manual fiddling to obtain the values.

Update:

During the past several years, the airport has pushed through – a guess here – nearly a quarter of a billion $s in airport improvements, especially in regards to re-aligning and lengthening runways. Even the the passenger load is now less than 15 years ago.

I found a story about the St Cloud, MN airport – which has built a shiny new air terminal but has no air line service and no passengers. The problem, the story suggests, is that the FAA’s airport improvement program spends money on poorly justified projects.
