SFO was impacted by a gate hold this morning that threatened to reach two hours.. specifically my frame for later in the day took 2h37 to get off the ground from push, and there were a lot of cranky pilots on the radio. What happened to cause something like that? I know it's in the reverse runway pattern from the wind, but they are running departures on both 10R and 10L with no interruptions so I'm confused what would cause a gate hold.
My best guess is that they swapped from the 28s to the 10s at some point and couldn't manage the resulting traffic snarl.
Meanwhile inbound is restricted to 19L arrivals, so that's bad times..
