Delta Airlines' quality rating keeps losing altitude

Via Wikipedia

Talk about a rotten trade: Delta Airlines, which now calls Minneapolis St. Paul International Airport one of its major national hubs after its takeover of Northwest Airlines, ranks just 15th out of 18 in the latest Airline Quality Rating from Purdue University and Wichita State University -- down from 12th the year before.

Northwest Airlines,meanwhile, held on to its fourth-place position before being assimilated into the Delta collective.

Sheesh. Can we get a refund?
