NW has "direct" service to tons of places. Let's see...

• LAX-PUS (NW 1)
• PDX-SIN (NW 5)
• SEA-ICN (NW 7)
• HNL-CAN (NW 9)
• DTW-PEK (NW 11)
• JFK-HKG (NW 17)
• MSP-MNL (NW 19)
• DTW-PVG (NW 25)
• SFO-BKK (NW 27)
• MSP-BOM (NW 42/46)
• SEA-BLR (NW 34 -- coming soon)
• DTW-TPE (NW 69)
• DTW-MNL (NW 71)

Of course all of these usually require switching planes in NRT or AMS (plus a couple of KIX/NGO switches), but they are "direct" flights.

You might want to change all instances of "direct" to "nonstop" in your post.
