Frontier Airlines launched new nonstop service Thursday from Fort Lauderdale-Hollywood International Airport to four major U.S. cities, and intends to launch flights to two more destinations later this week.

The Denver-based budget carrier is offering introductory fares of $29 to all six cities. They include:

Baltimore/Washington International Airport (starting Thursday).
Chicago O’Hare International Airport. (Thursday)
Dallas-Fort Worth International Airport (Thursday)
Detroit Wayne County Metropolitan Airport. (Thursday)
Charlotte Douglas International Airport in North Carolina (Friday).
George Bush Intercontinental Airport in Houston (Saturday).

All of the cities except for Houston will be served three times a week from Fort Lauderdale. The Texas destination will get a single flight each week.

Frontier said the additions push the number of its nonstop offerings to 12 cities from Fort Lauderdale-Hollywood International.

“With our launch of new service to Baltimore, Chicago, Dallas-Fort Worth, Detroit, Houston, and Charlotte, N.C., we are thrilled to offer South Florida consumers affordable travel to even more exciting destinations just in time for the busy holiday travel season,” Josh Flyr, Frontier’s vice president of network and operations design, said in a prepared statement.

From the airline, here are the terms of its $29 promotional fare:

“Tickets must be purchased by 11:59 p.m. Eastern time on Dec. 3. Sale fares are valid for non-stop travel on select days of the week, Dec. 3, 2025, through Feb. 28, 2026. The following travel blackout dates apply: Dec. 18-31, 2025; Jan. 1-6, 2026; Jan. 16-17, 19, 2026; Feb. 13, 15-16, 2026.

“A 21-day advance purchase is required. Not all markets are available for all dates of travel.”

In an August announcement unveiling the six-city flight additions, passengers were offered a range of one-way introductory fares of between $29 and $49, depending on the city. But now, $29 fares are up for grabs across the board.

Competitive shuffle

Frontier’s moves come at a time when its South Florida-based discount rival Spirit Airlines is downsizing while operating under Chapter 11 of the U.S. Bankruptcy Code. Some of the additions are in cities where Spirit is cutting back, such as at Chicago’s O’Hare International, where Spirit is relinquishing half its gates.

A Frontier spokeswoman said she could not say whether Frontier will be taking additional terminal space at Fort Lauderdale-Hollywood.

Spirit, which is headquartered in Dania Beach, has cut its systemwide capacity by 25% effective this month. It has dropped 14 airports, is terminating leases on 80 aircraft and furloughed hundreds of pilots and flight attendants, according court filings.

Frontier has sought to acquire Spirit multiple times, but without success.
