I can tell you Sat or Sun evening down to PFO is no fun as well you know often you can pick up extra 40 min ground delay and get your inbound figures at the last min.
Only a few weeks ago due to good conditions and friendly ATC we ended up on stand at 21:38 local but then due to them not being able to handle volume of pax passing through had 25 min delay so end up with 2hr 5min on the ground.
