WASHINGTON, July 29 (Reuters) - A U.S. appeals court on

Monday blocked the U.S. Transportation Department's new rule

requiring upfront disclosure of airline fees pending a full

review of the regulation.

The DOT issued final rules in April requiring airlines and

ticket agents to disclose service fees alongside the airfare,

saying it would help consumers avoid unneeded or unexpected

fees.

The 5th U.S. Circuit Court of Appeals granted the industry's

request to block the rules saying it "likely exceeds DOT's

authority and will irreparably harm airlines" pending a full

review by the court.
