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
downloaded
