Build a huge hub? Under NW, DTW WAS its biggest hub. Seeing that DL has added DTW-HKG, DTW-HND now, doesn't seem like DTW is going anywhere.

It boggles my mind why people think DTW should be dehubbed. It not only provides a great gateway to Asia and Europe, but in terms of connections, it makes total sense to keep DTW. For example, it's hard to fly from Asia to the east coast on UA unless you're going through ORD. For people on the east coast flying from Asia, getting home means arriving before midnight since you'd go through LAX, SEA or SFO, take a flight to another UA/CO hub (right now it looks like EWR, IAH are popular picks), then I'd be able to get home, at around 10-11 pm). With DTW, I get home on the east coast 4 PM at the very latest and I don't need to go through another hub. Why would it make any sense for anybody living on the east coast to go through LAX, SEA, SFO from Asia?
