According to a tweet from the FAA, "Southwest Airlines requested the FAA pause the airline’s departures."
We have had to implement a ground stop as a result of intermittent issues that were experienced, and we should hopefully be resuming our operation as soon as possible. I apologize for any inconvenience this may cause, but we'll be here for you if you need any assistance. -Katy
Why did Southwest Airlines have to ask the FAA to ground their flights? Couldn't they have done it themselves?
