There are three airports we recommend, the Detroit Wayne county airport, the Lansing capital airport and the Grand Rapids Gerald R Ford airport. Detroit will be the cheapest and have the most available flights but will be about a hour and a half drive. The Lansing airport will be the closest and but its price will be around 250 or less for a round trip per person. And Grand Rapids will be roughly the drive time as Detroit and be around the same price as Lansing. They might have better times though for flights depending on your schedule.
