Most of the travelers using Des Moines International Airport hail from areas outside the city, according to a late 2018 analysis conducted for the airport authority.

Why it matters: Airport officials are citing the data in calls for Des Moines' surrounding areas to contribute to a nearly $576 million terminal expansion.

By the numbers: Almost 60% of the airport's 3.4 million passengers in the second quarter of 2018 came from within a 90-mile area, according to the analysis of the most recent publicly available data.

  • Residents from nine suburban ZIP codes topped the list, accounting for more than 254,000 passengers.

Catch up fast: The airport's terminal construction is slated to begin in 2024, and a parking garage expansion could begin as early as next year, Clint Torp, the airport's operations director, told Polk supervisors last month.

  • Airport spokesperson Kayla Kovarna told Axios metro-area governments are being asked to contribute $34 million. They've agreed to just over $28 million so far.
  • State and federal grants will pay for $300 million with airport revenue and reserves picking up most of the rest.

Between the lines: Airport officials are reminding suburbs that the Des Moines Airport is a regional amenity with widespread benefit.

  • Local contributions are critical to leverage the federal grants.
