"We're going to be working to keep at least one runway clear just in case of flight diversions or an emergency," airport spokeswoman Mary Flannery said. "Other runways and taxiways will be cleared, too, in anticipation of resuming operations on Sunday." Travelers can rebook without a penalty fee, American Airlines said.

Nearly 300,000 recreational drone pilots registered their small unmanned aircraft in the first 30 days after a registration rule took effect Dec. 21, the Federal Aviation Administration said Friday. Because of the risk imposed by drones veering too close to airports, airplanes, and heavily populated areas, the FAA set up an online registration at www.faa.gov/uas/registration. Hobbyists who own a drone weighing between 0.55 pounds and 55 pounds have until Feb. 19 to register. Anyone flying an unregistered drone after Feb. 19 could face a fine and possible criminal charges, the FAA said. - Linda Loyd
