Fly from Chicago-ORD to Key West, Florida for $134 roundtrip on American Airlines this September.

It's tough to pin this fare down because the travel dates vary across the board by month. You will have the most luck traveling roundtrip in September at this price, but other limited days are available in additional months if you play around.

The best way to do that is by searching for one-way fares listed at $67 and piecing together an itinerary of two separate tickets.

As an example, I found seats searching on AA.com on flights departing ORD Tuesday, September 17, and returning from EYW on Saturday, September 21, 2019.

There are a lot of great deals leaving Chicago today, so make sure to pop on over to our O'Hare (ORD) and Midway (MDW) departure pages to see what else is available.
