What routes does the Delta Boeing 747-400 serve and does the economy class have individual TVs at each seat?

I’m pretty sure I answered another similar question last night from you!!!! Are you planning a trip on a 747 or what? here is a link to satisfy your question: http://www.youtube.com/watch?v=vAzgIk1fxnU
You can see how the Delta 747-400 looks like inside.

And this second link is for the Northwest 747-400: http://www.youtube.com/watch?v=qmHTW3zoNSo

As for the route you have to check on Delta and Northwest sites. They tell you what equipment does what routes!!
