What a ground stop at CPR means

When the FAA issues a ground stop for Casper-Natrona County 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 CPR ripples into the satellite airports and the whole TRACON; check the national board for programs at your alternate.

How long do ground stops at CPR last?

We have not recorded enough ground stops here yet to give an airport-specific average. Nationally, most stops run 30 to 90 minutes per issuance, but a stalled line of storms can keep one extended for hours.

Does a ground stop mean my flight is cancelled?

No. It means departures to CPRare held, not cancelled. Airlines cancel on their own when the backlog cannot be recovered, so watch your carrier's updates alongside this page.
