Ok, boarded UA 901 SFO-HNL on Monday night. Upgraded with UDU. When all of the F passengers are seated, but they are still boarding Coach, the Captain comes out of the cockpit. He then proceeds to personally introduce himself and shake the hand of each F pax. After that, he invites anyone who wants to come up front and sit in the pilot's seat where he will take your picture with your camera/ phone. Captain Mike Guymon, you made my day. I wish we would get that kind of treatment more often, but then if we did, it wouldn't be special!
