Southwest Airlines is terminating its San Antonio-Mexico City route, effective March 9.
The route will be replaced with the commencement the following day of a second daily flight between Houston-Hobby and Mexico City. With the addition, Southwest will offer both morning and afternoon service each way between the two cities.
In an email Friday, Southwest spokeswoman Thais Hanson said the adjustment in the airline's service to the Mexican capital was due partially to strict slot regulations at Benito Juarez Airport.
"We are making a change to address customer demand and offer the best itineraries to the greatest number of passengers wishing to fly between Mexico City and the rest of our network," Hanson said.
She added that San Antonio customers will have quick access to Mexico City through Houston.
