Spirit Airlines plans to provide nonstop service between San Antonio and Tampa as of next year. Starting January 11th, the low-cost carrier will fly from San Antonio to Tampa International Airport four times a week, on Mondays, Thursdays, Fridays and Sundays. So far the flights are scheduled only through April 5th, but airport officials hope that may change. Since beginning service in San Antonio a year ago, Spirit has added seven destinations including Tampa. Tickets for the new nonstop flights are on sale already.
