I agree with the above posters that Flint is a great airport and usually has better fares. But we're willing to pay higher airfares to avoid Detroit. My DH and I have discovered that the easiest (and cheapest) way to go is that I have DH drop me off with the luggage at the terminal, then he goes across the street to the economy parking lot and takes the shuttle back to the terminal. I go ahead and get in line, if there is one, while he's doing that. He's always rejoined me in less than 5 minutes. And we don't have to wrestle the luggage on and off the shuttle.
