Representatives from the low-priced airline joined city officials on the steps of City Hall Thursday morning to make the announcement. Southwest and Alaska Airlines also offer nonstop service to Cabo San Lucas.
The new San Antonio route comes on the heels of the airline's new service to Austin, Texas, which launched in April.
"The greater San Antonio and Central Texas communities continue to respond well to our "Low Fares Done Right" philosophy and we are proud to continue our commitment and bring even more low fares to San Antonio", stated Josh Flyr, vice president of Network Planning and Revenue for Frontier Airlines.
The airline is kicking off the service with a $59 special introductory one-way fare.
Frontier flies to more than 80 destinations in the United States, Canada, Dominican Republic and Mexico on almost 300 daily flights.
The flight will operate three times per week - on Sundays, Tuesdays and Thursdays - starting August 12. The flights mark Air Canada's return to Sacramento International Airport after a decade away, and continue a string of flight announcements to new cities for the fast-growing local airport. That was a 10.6 percent increase over the same month in 2017 and represented the highest level of traffic for any month on record (except July 2017).
