Took over an hour to get a PK242, $50 off a $100 fare applied to today's NW outbound, DL return. Required a call to Chisholm, 1 hour + on the telephone, a couple of calls by agent to his supervisor and bypassing the system to get the $50 bucks from a previously cancelled flight.

Seems that although we are told that NW is part of DL, not so unless the DL flight is a NW codeshare on this Certificate. Since they expire in September, it is "not necessary to fix this problem since it will soon go away". Yes, and how many of your previously inconvenienced customers will "go away" because your compensation is illusionary?
