So no delay was posted until well after our departure time. The inbound plane arrived maybe 20-30 minutes late since they were just deplaning when usually boarding is just starting. We only got the explaination from the pilot on taxiing to the IAH gate. Basically, the dispatcher with all the mess, never informed the crew what flight they were working. Not sure exactly if the crew that showed up was suppose to be our crew originally or not....

Customer First was certainly not being followed. Only 2 announcements in the 3 hours, no beverages/snacks, no meal vouchers offered. This was my biggest problem, in that though mistakes happen, it's how you handle the situation that makes or breaks the situation. CO failed on this operation.
