[08/05/2015 @ 12:34 PM] Removing from deal list until a fresh sale begins with a lot of availability on many days. There are a few days left where there is a sale, but not enough for this to be a deal for most of you.
American Airlines is offering round-trip flights from Dallas (DFW) to Belize (BZE) from $299, NONSTOPS available. Flights from October to June-2016.
Update: United is offering flights with a connection for $221. Their flights cover September and November, no weekend departures.
American’s cheapest nonstop flights start in November. Southwest flights have a stop, so the better deal will be the AA flights unless you like airports.
