The three airports I listed here are the only choices for nonstop flights from Europe on legacy carriers; if you connect in the USA, you wouldn't go through CBP at MSP.
Not everyone flying from Greece is either from Athens or originating trips from ATH on one-stop routings. From a bit outside Chicago to parts of Greece where some of my acquaintances go, some trips from door to door take close to twenty hours.
