Rochester now is only about 45 minutes from the Minneapolis airport. That said, as someone mentioned earlier, flight plans are easily changed.The plane is headed to Rochester, Minnesota this morning. Could be visiting Kaden Johnson? It's only scheduled to be there for 45 minutes though, and Rochester is over an hour from Minneapolis.
