WASHINGTON, Jan 28 (Reuters) - A U.S. appeals court on

Tuesday blocked the Biden administration's 2024 rule on upfront

disclosure of airline fees, saying the Transportation Department

had not complied with procedural rules.

Tuesday's ruling sent the rule back to the Transportation

Department to give it a chance to address the procedural errors.

Regulations issued by the Transportation Department in April

required airlines and ticket agents to disclose service fees

alongside the airfare, in a move to help consumers avoid

unneeded or unexpected fees.
