Frontier Airlines plans to add 16 routes to its network during the first quarter of 2025, including five city pairs served by embattled rival Spirit Airlines.

The expansion will mark Frontier’s return to Tucson, Arizona, for the first time since February 2022. The ULCC is also resuming services to Antigua for the first time since September 2022, and Reno, Nevada, after a break since February 2023.

According to OAG Schedules Analyser data, Frontier will face direct competition on 15 of the 16 routes. The only exception is between Antigua and San Juan, Puerto Rico, which was last operated by Silver Airways until May 2024.

Notably, 12 of the new routes are already served by two or more carriers, with Southwest Airlines present in 11 of the markets. Spirit and United Airlines each operate on five of the routes, while American Airlines and Delta Air Lines are active in four markets apiece, and Allegiant Air in one.

The network additions will see Frontier go head-to-head in five markets with Spirit, which filed for Chapter 11 bankruptcy protection on Nov. 18. They are between Austin-Bergstrom-Orlando, Nashville-Orlando, Houston-Tampa, Indianapolis-Tampa, and Las Vegas-Reno.

In its latest financial results for the third quarter of 2024, Frontier grew total operating revenue 6% year-over-year to $935 million as expenses fell 2% to $916 million. The carrier recorded a net loss of $26 million versus a $32 million loss the year prior.

The Denver-based airline’s overall capacity for November 2024 is running at about 3.75 million seats, marking a rise of about 56% compared with pre-pandemic levels. Of the 323 nonstop routes served this month, it competes with Spirit on 85 of them.
