- Frontier Airlines is launching new Las Vegas routes to Oakland and Boise, restoring two city pairs previously served by Spirit before its May 2026 shutdown
- Service levels remain below Spirit’s former capacity, with Frontier offering 11 weekly flights to Oakland and four to Boise, compared to Spirit’s 25 and seven
- With Spirit gone, travelers on many former Spirit city pairs are seeing higher average fares, fewer departure‑time choices, and reduced competition
Frontier Airlines is making another move to capture demand left behind by Spirit Airlines’ collapse. The Denver‑based ultra‑low‑cost carrier announced Tuesday that it will launch two Las Vegas routes previously operated by Spirit: Oakland and Boise.
Frontier’s new Las Vegas–Oakland service begins Aug. 20, 2026, marking the airline’s return to Oakland International Airport after exiting the market in 2023. Frontier will operate 11 flights per week.
A second route, Las Vegas–Boise, launches Sept. 10, 2026, with four flights per week. Boise had been one of Spirit’s smaller but steady western markets before the carrier ceased operations.
“We are laser‑focused on redefining what consumers can expect from low‑fare travel — from our expansive network map to the premium upgrades we offer — and we look forward to providing consumers with affordable flight options on these new routes,” Frontier VP of network and operations design Josh Flyr said in a press statement announcing the news.
Still Behind Schedule
The new Las Vegas routes represent two of the 16 that Spirit abandoned when it shut down on May 2, 2026. Spirit’s exit removed thousands of weekly seats and roughly 70 daily departures, creating the largest single‑day capacity loss in Harry Reid International Airport’s modern history.
While no U.S. city lost its only nonstop link to Las Vegas, the number of daily flight options — especially in the budget tier — dropped sharply. Spirit had operated 25 weekly flights between Las Vegas and Oakland and seven weekly flights to Boise. Frontier’s replacement service restores only 11 and four, respectively, leaving both markets with fewer low‑fare seats than before.
Southwest Airlines, already the dominant carrier at LAS, has actively increased frequencies on several West Coast routes, including Oakland, during its post‑Spirit expansion. However, Southwest has not added new Boise service, leaving Frontier as the only airline replacing Spirit’s ULCC‑level competition on that route.
With Spirit gone, travelers on many former Spirit city pairs are seeing higher average fares, fewer departure‑time choices, and reduced competition — a shift airlines have acknowledged as they rebalance capacity heading into the 2026–27 travel seasons.
