Travel down to the most southern point in the contiguous 48 states with this fantastic fare from American Airlines. Flights from New York-LaGuardia to Key West Florida are available for just $163 roundtrip for travel this September and into October.
Tickets at this price are available on select travel days starting in early September through October 1, with returns possible through the end of October. Most departures are valid on Sunday through Wednesdays, with return flights from MIA on Tuesdays through Fridays. Other days of the week may be available.
On some itineraries a long layover in Miami might be required on the return segment but if you are flexible with travel dates they can be avoided.
As an example, I found seats available departing New York LGA on Tuesday, September 24, and returning from Key West EYW on Thursday, October 3, 2019, with quick connections on both legs of the journey.
This Basic Economy fare includes a carry-on bag plus one personal item. A checked bag costs $30 each way.
Seats will be assigned at random upon check-in for this price.
American's Main Cabin Economy fare is $223 roundtrip, which includes advanced seat assignments and allows ticket changes/upgrades for a fee. A checked bag will still cost the same $30 each way.
