Frontier Airlines is making a push to be top-of-mind for travelers in South Texas, South Florida and Michigan.
The budget airline on Tuesday announced a big network shakeup, unveiling 20 new or returning routes covering 14 cities, from the U.S. to Mexico and Central America.
It’s the latest in a series of shakeups we’ve seen from Frontier over the past two years, amid financial pressures. Increasingly, the carrier has aimed to transport customers flying between major cities to visit friends and relatives or for work — not just vacationers headed to places like Orlando and Orlando.
The big winner in Tuesday’s announcement: Houston’s George Bush Intercontinental Airport (IAH), which is getting eight new Frontier routes to the likes of New Orleans, Fort Lauderdale, Guatemala and Honduras, among others.
Fort Lauderdale-Hollywood International Airport (FLL) will see a half-dozen new Frontier flights, and Detroit Metropolitan Wayne County Airport (DTW) will get five additional routes.

The carrier did not announce any route cuts or pullbacks as part of Tuesday’s announcement, but such changes are common when there’s a big network shakeup at an airline.
Not all of these routes are entirely new. In fact, Frontier offered CUN service from BWI and DTW as recently as 2024, but cut those flights amid stiff demand to the popular Mexico beach destination.

The carrier last operated its DTW-MIA and IAH-PHL services in 2022.
On the other hand, Frontier’s deep ties to Houston are a much more recent development. Even prior to Tuesday’s announcement, the ultra-low-cost carrier was set to offer 158% more departures out of IAH than it did just two years ago. IAH also remains a major hub for United Airlines.
Loyalty changes in the works
Frontier has changed more than its route map in recent years as it has proved less profitable than the larger network airlines (as have other budget airline competitors).
A year ago, the carrier revamped its longstanding fare bundles and introduced an UpFront Plus seating product it has compared to European-style business-class, featuring a blocked middle seat.

It also made sweeping changes to its Frontier Miles loyalty program, including introducing a companion pass for travelers who earn Platinum-level status.
Last week, Frontier said it would offer automatic Gold status for $69 to any loyalty members of Spirit Airlines, Southwest Airlines, Alaska Airlines or JetBlue. Gold status on Frontier will soon come with complimentary, space-available upgrades to its soon-to-be-introduced first-class seats, set to debut by the end of the year.
