Definitely crossed my mind during my exchange with the FA. I asked him to refresh his app, and of course showed him my BP in the app

He said his app is updated. He informed me at the end this happens from time to time, but not exactly in a reassuring manner.

Had a similar experience yesterday. But mine was apparently due to clearing the upgrade after boarding--the FA showed my seat as empty. She greeted my wife (on a separate res) and thanked her for being a 1K, as did the next FA... I got, "I don't have you on this flight. There's no one sitting here according to what I see. What's your name again?" Lots of back and forth, like you saw.

Even once resolved, not a single, "Thank you for being a 1K." It was very off-putting overall.

I just got this Non-alcoholic drink option for a trip later this week, when I got alcohol options on the outbound leg last week????

Had a flight last week (ATL-DEN) where I was charged for both my drink and snack box. Sat in the bulkhead, FA forgot about my snack box order and moved on before giving it to me but did give me the drink. Finished drink, hit the head and asked for the snack box again while I was back there.....never acknowledged 1K so maybe I need to clarify from now on (hate pulling the status card, I just want my measly benefits). Got an email after I got home with my "receipts" that was completely blank, just had the subject of the flight but no other details. Now those charges are posted to the CC and I've reached out to customer care. This January has been a cluster.... of disappointment with United with all my other changes, cancelations etc. (some related to Max 9, others not) which just hasn't been the case for me the last couple years.
