MSP-NRT increases from 8x weekly to 10x weekly. The new frequencies also operate with B744. Before anybody asks, the slots came from HNL-NRT, which is going to 14x weekly this summer vs. 17x weekly last summer.

The return of the fifth DTW-AMS is a surprise. I would've liked to see the 2300 departure, like the old NW60 though.

Ah, didn’t we repeatedly read on airliners.net that this service would fail miserably?

Worth noting: they've added these new flights, but they haven't made any changes to existing ones (in other words, the timetable's otherwise the same).
