[11/16/2015 @ 7:46 PM] The HOUSTON Deal looks like it’s been pulled or has sold out. It’s no longer bookable on any OTA. DALLAS still seems available via a United match. Updating post to reflect that United is now the carrier. American Airlines has pulled their fares.
[11/17/2015 @ 1:23 PM] Fare gone. Removing from deal list.
United has round-trip flights from Dallas (DFW) to Kailua-Kona, Hawaii (KOA) for $490 with a connection. Flights from December to May.
There are currently a few flights near New Years Eve. Those are probably going to be gone really quickly.
