That was a long, relatively complicated read.
So should the summary of what you said be that "irregular operations consume too much time for both NWA passengers and NWA employees"?
If it's any consolation, I had to stand in line twice (for at least two hours each go through) at the ticket counter to get rerouted when NW 1 from LAX to NRT got cancelled yesterday. It was a massive mess, with frayed nerves on all sides, and the agents still had to check in the AMS / DTW / MSP people all while trying to reroute & accomodate. It's amazing anything can get done when things like this happen.
It'd be nice if the airline kept agents "on-call" for when irregular ops happen.
