<p>The MSA Airbus is still the cheapest way to get between campus and airport during fall break/T-gives/end of semester, but for any other time this appears to be the best option (assuming you don't know anybody who can drive you themselves). This would probably be most useful for prospective students or people going to orientation.</p>
<p>Ann Arbor Transportation Authority (better known as AATA) has re-routed their #36 Wolverine Tower shuttle bus to service the Sheraton Hotel for this purpose. It's free for U of M students if they show their Mcard, $.50 for high school students (may be asked for identification, but usually not), and $1 for everybody else.</p>
