Over 400 passengers were stranded at Houston's Hobby Airport during Hurricane Harvey. Flood waters had submerged all roads to and from the airports. The airport terminals were holding up well, but no one knew how to evacuate the travelers trapped inside. When flooding receded slightly from the Hobby runways, Southwest Airlines got special permission from the Federal Aviation Commission to fly five rescue flights to Love Field in Dallas, outside the storm zone.

Airport passengers waited calmly in lines by the gates to board the rescue flights, and applauded the food service staff who kept them fed. In total, 486 passengers (and some Southwest employees) were evacuated to safety, leaving only 17 people in the terminal -- mostly local residents. Southwest put evacuees up in Dallas hotels until they can be rebooked.
