I'm at the bayshore Marriott watching flights coming into SFO and operations look to be running smoothly now that the rain has stopped. There is still a low cloud cover so not sure what delays are in effect by ATC. I can see some blue sky in the distance so hopefully it will be cleared up by later tonight.
The SYD flight doesn't leave until 10:40p and I'm sure the pilot will work to make up some time in the air from PHL. I'd say there's a high probability that they will make it.
