September 1997 Continental Airlines announced it would consolidate its Houston headquarters in the Continental Center complex; the airline scheduled to move its employees in stages beginning in July 1998 and ending in January 1999. Bob Lanier, Mayor of Houston, said that he was "tickled to death" by the airline's move to relocate to Downtown Houston. Tim Reylea, the vice president of Cushman Realty, said that the Continental move "is probably the largest corporate relocation in the central business district of Houston ever." Hotel operators in Downtown reacted favorably, predicting that the move would cause an increase in occupancy rates in their hotels. In 2008 Continental renewed its lease in the building. Before the lease renewal, rumors spread stating that the airline would relocate its headquarters to office space outside of Downtown. Steven Biegel, the senior vice president of Studley Inc. and a representative of office building tenants, said that if Continental's space went vacant, the vacancy would not have had a significant impact in the Downtown Houston submarket as there is not an abundance of available space, and the empty property would be likely that another potential tenant would occupy it. Jennifer Dawson of the Houston Business Journal said that if Continental Airlines left Continental Center I, the development of Brookfield Properties's new office tower would have been delayed. As of September 2011 the headquarters moved out, but Continental will continue to house employees in the building. It will have about half of the employees that it once had.
