Like the poster above who is trying to get back from Florida just days after the May 10th schedule, I had our first half booked, but ended up booking a one way back on Northwest. I am from the Detroit area and try to avoid flying them at all costs, but today, they had $83.90 all in one way fares, and I snapped up 4 tickets for a one way and will not look back. It looks like many of the legacies will post one way fares (of course not with the same refund policies of Southwest) at the same low prices as Southwest where they compete on the same routes. I noticed that DTW-BWI ($49), DTW-MDW ($49), DTW-STL ($59), DTW-BNA ($59), DTW-LAS ($79), DTW-PHX ($79), and DTW-MCO ($83) were all available from Northwest as bookable one way trips. Coincidentally, those are all the same routes where Southwest flies non stop from Detroit.
