Frontier Airlines, which is headquartered in Denver, announced a new pricing plan Friday, putting an emphasis on transparency in the midst of the Biden administration’s efforts to require airlines to disclose service fees alongside airfare.

Frontier is referring to the changes, which include transparent pricing, no change fees and “enhanced customer experience,” as “The New Frontier,” saying the changes are part of the airline’s efforts to provide high value travel experiences.

The airline will now offer basic, economy, premier and business travel options, “designed to meet various customers’ needs and budgets,” the airline wrote in a news release Friday. 

Basic will include a personal item with other amenities available for purchase. 

Economy includes a carry-on bag and standard seat assignment.

Premium includes a premium seat assignment, carry-on bag and priority boarding.

Business includes “UpFront Plus” seating with extra space and comfort, carry-on bag, two checked bags and priority boarding.

The airline will also stop charging change or cancellation fees for economy, premium and business flights, according to the release. 

They are also extending flight credit expiration time to 12 months and a price match guarantee, meaning customers who find a lower price somewhere else will get 2,500 Frontier miles, the release said.

“Today marks the beginning of a new era for Frontier – one with transparency in our prices, no change fees and the lowest total price,” Barry Biffle, the CEO of Frontier, said in the news release. “No gimmicks, just really low prices and good customer service.”

Frontier is also upgrading its website and app to “simplify your travel planning” and improve their flight update system, adding extra notifications, according to the news release. They will also have live phone support for customers within 24 hours of their flight.

The announcements come in the midst of tension between major U.S. airlines and the U.S. Transportation Department, with several airlines suing the department over a new rule requiring upfront disclosure of airline fees, according to a Reuters report. 

Lobbying group Airlines for America, along with American Airlines, Delta Air Lines, United Airlines, JetBlue Airways, Hawaiian Airlines and Alaska Airlines, filed suit against the department (USDOT) in the U.S. Fifth Circuit Court of Appeals in Louisiana late on Friday, according to a copy of the suit seen by Reuters.

The USDOT issued final rules last month requiring airlines and ticket agents to disclose service fees alongside the airfare, saying it would help consumers avoid unneeded or unexpected fees.

The airline group said in a statement on Monday the department’s rule would confuse consumers and that its “attempt to regulate private business operations in a thriving marketplace is beyond its authority.”
