Frontier Airlines is picking up 8 routes Spirit Airlines used to fly, and it’s using the moment to remind everyone why it calls itself America’s Low Fare Airline.

The new nonstops connect major markets like Boston, Dallas, Detroit, and Las Vegas, with flights starting today and tomorrow. Frontier is backing the launch with introductory fares as low as $39, giving budget-conscious travelers a fresh set of cheap options right as summer travel ramps up.

These are the new routes and schedules.

Frontier Airlines’ 8 New Routes

Frontier‘s expansion touches 9 airports and covers a mix of daily and multi-weekly service. It’s moving to fill gaps (and hopefully gain customers) left behind when Spirit Airlines ceased operations.

Most of these routes run daily, though the Kansas City-Las Vegas pairing and the Orlando routes to Memphis and Richmond operate 3x and 4x weekly, respectively. As always with new route launches, frequencies aren’t set in stone, so check flyfrontier.com before you build a trip around one of these flights.

Hot Tip:

The $39-and-up intro fares are only bookable through 11:59 PM ET on July 12, and they apply to travel between August 3 and September 2, 2026, on select days of the week. A round-trip purchase isn’t required, so you can grab a one-way at the sale price if that’s all you need. Book early if your dates are flexible; not every route will be available throughout the entire travel window.

Final Thoughts

Route gaps left behind when an airline shuts down or pulls back rarely stay empty for long, and Frontier is moving fast to claim this territory.

If any of these city pairs align with your travel plans, the introductory fares offer an easy way to try the airline’s new seating and service changes. Just book before the July 12 deadline, and keep an eye on Frontier’s website in case frequencies or flight times shift.
