Hurricane Harvey continue to recede, officials said.'s two major airports resumed limited flight operations Wednesday afternoon as floodwaters from
George Bush Intercontinental Airport and William P. Hobby Airport resumed limited service for domestic flights at 4 p.m. CT.
"We will attempt to begin a phased return to service, with full service expected by this weekend," both airports said on Facebook.
The airports cautioned that many roads in Houston remain flooded and said only confirmed ticket holders on scheduled flights should travel to the airport. It could take two to three days for airlines to resume their schedules, the FAA said.
Southwest has canceled all flights to and from Houston Hobby Airport until Saturday at noon. United is operating a limited schedule.
"We have good news," said Jeff Lindner, a meteorologist with the Harris County Flood Control District. "The water levels are going down. And that's for the first time in several days."
Nevertheless, many thousands of homes in and around the nation's fourth-largest city were still swamped by the record-breaking deluge of 4 feet of rain and could stay that way for days or weeks. And officials said 911 call centers in the Houston area were still getting more than 1,000 calls an hour from people seeking help.
