At MIA flying to DEN and was meant to leave at 7:37am and our flight has been delayed several times due to a security incident. The TSA checkpoint is closed and apparently the crew cannot get through. Gate agents are saying that nobody is allowed in or out. We’re in the G gates and I’m wondering if anyone has any idea what’s happening. I walked to the checkpoint and it’s completely closed. No agent. Nobody in line. Nothing. Any ideas?
