Airport Information System

The Airport Information System is an online program that provides the public with information about Washington's air transportation system.

Each airport in the state is able to update their information online and print reports. We use the information to measure aviation system performance over time and communicate improvement needs to decision makers. Airport sponsors are encouraged to log in, review and update their existing data at any time during the year as information changes. However as a condition for grant eligibility, airports are required to acknowledge their review and update by December 31 of the preceding calendar year. We create a benchmark of the data for each year.
