This situation appears to have been totally mishandled.
I assume both tickets you had purchased on CO and DL were not bulk fares and that both tickets were acessable to NW, if the agent printed both tickets, that would lead to a problem with you using them on the original carriers. Was this attempted prior to 12/10 when NW established an E-tkt link with DL?
I would suspect that the agent you spoke to at the ticket counter got wind that you then spoke to the gate agent about the same thing and received a different (and correct) answer...they advised the supervisor and it went from there. Basically an ego problem with someone that was wrong, was overridden, and wanted to show you who was running the show. I would get names of everyone you talked to and submit them with your note to Customer Relations. The BUMP program still exists and was recently mentioned in an internal memo "Q & A" as to it's current validity...as the program is several years old and not heavily promoted within the company (to say the least), I would estimate at least 50% of customer service agents are not familiar with it. It is not necessarily something NW wants to make public knowledge, for lack of better terminology, as to not encourage someone to purchase a less expensive fare on another carrier and then fly NW with it. The program is designed to capture revenue on day-of-departure only to fill empty seats. Why a supervisor would actually remove you from an aircraft, even if NW was only getting $10.00 for the ticket(s) you purchased, is beyond me and as I said, at least on the face of it, wrong.
Curiously, did you speak to the GA afterwards?
