Southwest Airlines received support from Houston's aviation director for international service from William P. Hobby Airport. The ultimate decision will be made by Mayor Annise Parker and the Houston City Council. Should the proposal pass, negotiations with Southwest will continue over construction of a Customs facility and an international terminal that could cost $75 million to $100 million. "Southwest has pledged to cover the cost through an increase in the passenger facility fee," to $4.50 from $3, the Houston Chronicle says. Parker plans to schedule "a vote on the agreement for next month," the newspaper says.
