On March 23, 2018, the President signed H.R. 1625, the Consolidated Appropriations Act, 2018. The legislation provided the Federal Aviation Administration's (FAA) Airport Improvement Program (AIP) an additional $1 billion in discretionary grants, to enable the Secretary of Transportation to make grants for projects as authorized by subchapter 1 of chapter 471 and subchapter 1 of chapter 475 of title 49, United States Code.

• Corrected list of Airports eligible for 'Priority Consideration' as of October 19, 2018 (PDF) (added 10/25/2018)
  This is a correction to the 10/19/2018 Priority Consideration list. The corrections do not impact any airports. Since posting the list on 10/19/2018, we discovered the following three issues: (1) Duplicate listings, (2) The bullet point summarizing the changes (quantity of additions and removals) to the Priority Consideration list was incorrect, and (3) The 'as of' date at the top of the nonprimary airports table had not been updated. This version corrects all three issues. Despite the duplicates, the individual airports on the October 19, 2018, list were correct. The duplicates also had no impact to the State totals.
