When you take your car in for repairs, they give you an estimated time. There is no difference here. Mechanics get a BASIC idea of the problem when dispatched by mx control. It isn't until they arrive at an airplane and do their job, that the whole picture is discovered. THAT is why most delays are "rolling." We're also required to update every 15 minutes, with or without news, so that you're all kept in the loop, which is where your dreaded creeping 15 minute announcements come from. Sometimes we don't have the whole story or an accurate story to tell you. Passengers just have to have patience and flexibility when something irregular occurs.

Ops swapped gates and we found out when all the MSP pax marched into the boarding area; looking up at the monitor I could see that it now read MSP with their flight monitor. When I walked over to 2, our flight was listed as CX.

Since these were the last flights of the day, I hustled down to the counter, only to be told it would be a couple of days until NW could get me to WAS (high loads). I ended up staying home that week after declaring "trip in vain" and getting a full refund on a "non-refundable" Y fare. The work suffered a slight bit, but I didn't feel it good stewardship of the Company's money to fly down there for only a day's work (Thu).

So, again, be glad everyone made it that day.
