Ultra-low-cost carrier Spirit Airlines said Thursday that it will begin nonstop daily service between Denver and San Diego starting Jan. 6.
The airline’s booking engine shows a 7:25 a.m. flight leaving Denver and an 8:45 p.m. flight leaving San Diego. It lists a fare of $43.09 for each leg, excluding baggage fees.
A comparable roundtrip flight leaving Jan. 12 and returning Jan. 17 is running $151 on Frontier Airlines, $204 on Southwest Airlines and $235 on United Airlines.
. It currently offers direct flights from Denver to Las Vegas; Fort Lauderdale, Fla.; Minneapolis-St. Paul; Phoenix; Chicago O’Hare; and Houston’s Bush Intercontinental.
Spirit’s previous owner, Indigo Partners, acquired Denver-based Frontier a year ago from Indianapolis-based Republic Airways Holdings for $145 million and has converted it into an ultra-low-cost carrier. Spirit is now a public company.
