What a ground stop at LAS means
When the FAA issues a ground stop for Harry Reid Intl, aircraft headed there are held at their departure airports until it lifts; flights already airborne continue, hold, or divert. It is the FAA's most severe traffic-management step short of closing the airport, and it is usually issued in 30 to 90 minute increments that get extended while the cause persists, then often converted into a ground delay program as conditions improve.
Passengers:your aircraft is probably sitting at its origin; the airline's "delayed" status usually resolves in waves after the stop lifts. Pilots: a stop at LAS ripples into the satellite airports and the whole TRACON; check the national board for programs at your alternate.
