A few days ago I was heading over to DEN on COCO for a somewhat tight onwards connection -- however once everyone had boarded and gotten settled we had a delay as a good number of bags had not yet been loaded due to some foul up with the IAH baggage system. Thinking it would be 15-25m delay I sat in my bulkhead seat listening to chatter from the galley where the FAs were commenting on the lack of hot water as the pre-departure coffees that my fellow F passengers had requested could not be fulfilled. As soon as they got the bags loaded the pilot announces a MX delay for the water system at which point I excused myself to the top of the jetway to discuss alternate routes with the GA. While we were working on rebooking my ticket, the GA at the pilot for waiting till the last second to report the water issue commenting on that if he had simply called it when we started boarding it would have probably been fixed, or at the least MX would have been there working on it during our delay for the bags. However, seeing as he waited until after the bags were loaded to report it, the delay would not be longer (and the FAs were aware of the issue from pre-boarding since they could not accommodate the coffee requests, so one would assume they let the flight deck crew know as soon as they discovered the issue.) Anyways the reason I mention this is because I'm curious as to if anyone knows what kind of mood labor, especially ALPA, is in right now. Obviously I don't think too much can be read into what happened to me on my flight, but it does raise the question in the back of my mind if the pilots/GAs/FAs/handlers/etc. are planning on any kind of (un)official action in the near future.
