Seattle’s Boeing Field and the Yakima Air Terminal have a choice: Let Immigration and Customs Enforcement (ICE) flights land at the airport or risk future money from the government.

It started in April when King County Executive Dow Constantine issued an order to rid Boeing Field of ICE flights.

While Boeing Field does not have a contract with the agency, a ground operator at their airport had a contract with Swift Air, which had a contract with ICE to transport undocumented immigrants.

Earlier this month, that operator ended its relationship with Swift Air, effectively terminating ICE’s ability to move immigrants through the area.

Now those flights are landing at the Yakima Air Terminal in central Washington.

Cliff Moore, the Yakima city manager, has witnessed three of those flights. On Mother’s Day, he watched as 42 detainees were deplaned and walked onto buses.
