I think I am the only one that might not mind. The lions share of my travel is to Europe, and while I like the 330s the difference in service between DL BF and NWA WBC is miniscule. However, living in DTW it is my opinion(ok hope) that much of the combined ITNL travel would be moved to DTW from JFK, ATL and CVG....
See I have this dream of DTW-NCE no-stop(my usual destination) and a DL/NWA merger would make it more likely, and even if not - there would at least be more destinations served in Europe more easily out of DTW.
