**Before anyone says that Lufthansa must be on drugs, keep in mind that Colorado's 2nd largest minority are Germans after Hispanics. Primarily from the Bavarian region of Germany which is where Munich is located.**
If airlines decided that population of ethnic groups in a city was the reason they would expand their routes...
would have more than one weekly Royal Jordanian A310 flight. Basically if that were the case then DTW
would have daily flights from almost any of the majors from the Mideast because of Detroits large Middle Eastern population and yes a majority are recent immigrants or 2nd generation, unlike the Germans in Colorado that have been there since the 1800s.
If that were a reason to expand, then large cities like Detroit, LA
, Chicago and whoever else has a large African American population should see flights from SAA etc regularly too.
