How did we take off during a ground stop?
Not specifically an AA question, but I was flying AA so I will start here. Curious about something. I flew to MSP today, which had a big snowstorm.
There was first a ground delay, then a ground stop. Ground stop was scheduled to end at 3:30 ET. We boarded plane before this. Shortly before we departed gate, ground stop was extended to 4:30 ET.
I assumed we would not leave gate. I was pleasantly surprised when we did. We took off before 3:30, which was before the original expiration time of the ground stop.
As a layman, I am guessing that there are “exceptions”? I am just curious, if anyone in the industry can explain how this actually works. The language on the FAA site made it sound like “no one is allowed to take off to this airport”. But, there must be some grey area?
