Airspace Designations and Reporting Points: Vicinity of Laredo, TX

What it does

• •Proposes to amend Jet Route J-21 by shifting its southern segment intersection at the U.S.-Mexico border from the TTXOX waypoint (Laredo 163°M/172°T radial) to the DAPUN waypoint (Laredo 165°M/174°T radial), located 0.93 nautical miles southwest.
• •Eliminates a 1.47-degree turn where the Mexican segment of J-21 joins the U.S. segment, thereby straightening the airway's ground track.
• •Leaves the remainder of J-21 unchanged, with the route continuing from the new border intersection through Laredo, San Antonio, Centex, Waco, Ranger, Ardmore, Will Rogers, Wichita, Omaha, and Gopher to Duluth, Minnesota.

Why it matters

• •The straightened route is intended to improve operational efficiency by eliminating an unnecessary turn in the jet airway structure within the National Airspace System.
• •The FAA determined the proposal involves only routine, technical amendments to established regulations and will result in de minimis costs to operators, with no significant economic impact on small entities.

Who is affected

• •Aircraft operators using Jet Route J-21 between the U.S.-Mexico border and Duluth, Minnesota.
• •The FAA and pilots navigating the affected airspace in the vicinity of Laredo, Texas.

What happens next

The FAA will accept public comments until December 28, 2026, consider all submitted comments before taking final action, and publish updates to FAA Order JO 7400.11 if the proposal is adopted.
