I'll bite....
Jumped on UAL 3 weeks ago, was warmly greeted by the CA with a few lighthearted smart a$$ comments, the FO piped up with his own and I naturally threw them a few of my own back. CA said to grab a "good seat" and enjoy the ride. If the ride was bad the FO was to balme.
The CA came back to personally welcome those of us in first class and brief us on the flight before departure, something I thought was a nice touch for those actually paying out the nose for this kind of service.
The "A" FA was great, served a meal, wine and fresh cookies along with a movie instead of the stupid "short subject" video was supposed to be played.
Starbucks coffee was also served of course.
I've jumped on UAL many times and had good and bad experiences. This was the first flight I'd been on where I was taken care of so well all the way around.
