Nine airports, including Houston’s two main airports – George Bush Intercontinental Airport and Hobby Airport – remain closed Monday as the region continues to grapple with devastating flooding throughout the area. San Antonio International Airport and Austin-Bergstrom International Airport are also shut down.

Officials had hoped to reopen Bush Intercontinental by noon Monday, but scrapped those plans. Both Bush Intercontinental and Hobby Airport are expected to stay shut down until at least Wednesday.

The torrential rain and flooding in Houston, a large hub for air travel, prompted the cancellation of at least 40 flights at LAX Sunday.

Several passengers remain stranded at LAX, including Clayton Atkins. The Dallas resident says there is not direct United Airlines flight between there and Los Angeles, so without Houston as a hub, he is unable to get home.
