American Airlines have round trip airfares travelling from Detroit (DTW) to Cancun, Mexico (CUN) for $173-$176, making 1 stop. These are basic economy fares but also a flexible travel fare. While in Mexico, I recommend staying at all-inclusive resorts for value and convenience.
Departs DTW: Aug 1-31; Sept 1-30; Oct 1-31; Nov 1-10
Returns: wide and great availability returns
