The Biden administration is on a mission to crack down on junk fees. Here's who's fighting to keep them.

• President Joe Biden earlier this year said his administration would crack down on hidden fees.
• But lobbyists are pushing back against proposed rules that could boost transparency, per WaPo.

From a dizzying array of airline fees to add-ons tacked on to concert ticket prices, Americans are fed up with hidden fees.

And they have an ally in President Joe Biden, who during his State of the Union address earlier this year vowed to crack down on the add-ons, often called junk fees, which when affixed to subtotals can make a simple hotel stay or a round-trip flight financially out of reach.

Biden wants to go after the practice and push companies to increase pricing transparency for consumer purchases, and his administration has targeted a swath of industries across the larger US economy, from airlines and ticket sales companies to banking institutions and credit card companies.

But corporations and their lobbyists are aggressively fighting back against proposed rules that would compel them to be more transparent about hidden fees, according to The Washington Post.

The Post analyzed federal lobbying files and filings sent to federal agencies as the administration pushes to save US consumers from collectively spending billions of dollars in fees each year.

One area where consumers have often lodged complaints is toward the airline industry. Travelers have long spoken out in favor of airlines revealing the true cost of tickets earlier in the sale process. And Biden wants airlines to oblige to what consumers have asked for regarding pricing.

But major US-based airlines, including American Airlines, Delta Air Lines, and United Airlines, are not thrilled with the prospect of such a change, which consumers have advocated for in numerous letters submitted to the Department of Transportation (DOT).
