Frontier Airlines adds 20 new routes focusing on Houston, Fort Lauderdale and Detroit

Frontier did not announce any route reductions or eliminations as part of this update. However, adjustments to flight schedules are common following major network changes. Some of the newly announced routes are returning after previous suspensions; for example, service from BWI and DTW to Cancun was last offered in 2024 but was discontinued due to fluctuating demand.

The carrier’s expansion at IAH marks a recent shift in its operations. Prior to this announcement, Frontier was already planning to offer 158% more departures out of Houston than it did two years ago. This comes as IAH continues to serve as a major hub for United Airlines.

In addition to route changes, Frontier has made several updates to its loyalty program and fare structure over the past year. The airline introduced an UpFront Plus seating option with a blocked middle seat—described by the company as similar to European-style business class—and restructured its fare bundles.

Frontier also updated its loyalty program by adding a companion pass for travelers who achieve Platinum-level status. Last week, the airline began offering automatic Gold status for $69 to members of Spirit Airlines, Southwest Airlines, Alaska Airlines or JetBlue loyalty programs. Gold status on Frontier will soon include complimentary upgrades—when available—to first-class seats expected later this year.

"Frontier's deep ties to Houston are a much more recent development," according to the release. "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."

The latest changes come amid financial pressures faced by budget airlines like Frontier as they compete with larger carriers for both leisure and business travelers.
