Fifth Circuit Vacates DOT Fee Transparency Rule After Airlines Challenge Procedural Violations
The Fifth Circuit Court of Appeals vacated the Department of Transportation's rule requiring enhanced transparency of airline ancillary service fees on February 3, 2026, after the DOT conceded it failed to follow proper Administrative Procedure Act rulemaking procedures. A coalition of major U.S. airlines, including American, Delta, United, and Spirit, had challenged the rule's implementation.
