No, if you read my original post, you'll see my argument is that this does honor seniority because all the available slots were filled in seniority order, then the junior people whose base were closing were also allowed to go to a filled spot. Yes, there are some people who feel aggrieved that the junior bumped people shouldn't have been able to go to a seat without offering it to a more senior person, but that senior person wouldn't have gotten the seat because the seat was already filled.

You are advocating for a bump and flush which would (and has in the past) cause more havoc throughout the crew force and negatively affect so many more people than this bid system does.
