In aviation business news, beginning this summer it appears Delta will add a new European destination from Metro Airport in Munich, Germany.
While I am not aware of any formal announcement, during a search on the Delta website for the summer 2016 months, I stumbled across a bookable nonstop flight between DTW and Munich that appears to be almost daily. It sure would be nice to have a direct flight for traveling to and from Bavaria, and would be another feather in the cap for DTW's international air service if true.
