There are cheap round-trip flights from Houston (IAH) to Curacao (CUR) on sale for $259 right now. Availability is pretty much limited to February 2015. Other dates are possible but they cost more and require long, overnight stopovers in Miami. The itinerary used in this post avoids the long overnight stopover (for now).
[08/25/2014 @ 10:54 PM] Prices have increased to $290.
[08/27/2014 @ 3:13 PM] Looks like this deal is ending soon. You can probably still find tickets by booking directly with American Airlines.
