The rumors on the DL board are that the reservations system for NW will be shutdown on 2/1 and the former DL system will handle everything. The rumors also suggest that nwa.com will be shutdown at the same time.
oh joy. That will be the day the NW website takes 3 steps back to 1997. DL has one of the lamest sites in the industry. Nobody still holds a stick to the AS site (maybe WN or FL comes the closest but are still pretty far off). But as far as legacy domestic carriers go, DL is one of the worst if not the worst website around
