Is there a handy site that can show me the routes for these particular jets? Or is it a manual search thing? A rep at the sky club mentioned that the 747 may fly a lot out of MSP since it's a former NW plane ...
I believe most or all of the 747s are used on routes to Asia. Mostly out of MSP and DTW but they change planes on routes all the time. I think delta has 16 of them with at least one in for a retrofit right now.
The 777s do a lot of routes to Asia as well but also do LAX-SYD, ATL-JNB and ATL-DUB along with some others I am likely missing. I don't know of any source to see exactly what route each plane is on but if you are looking into travel because of a plane type I'd go with the 777 right now. They are all pretty new and have flat beds in J and AVOD in Y. The 747 are just starting to be updated so you are likely to get an old NW layout with no AVOD in Y and the old NW seats in J.
Plus a summer seasonal addition to the DTW-AMS flights.
As already mentioned, MSP-NRT will be switching to a 777
later this fall (October 29th to be exact). You can download the
DL flight schedule from their website and search for the term
"744". You need to be careful and only pay attention to flights
listed with 0 stops and that have actual Delta flight numbers (not
code share partner flight numbers). Flight schedules can be
