Bill,
Airline tickets vary a lot in their return requirements. Some are good only for short periods, others for a year. Basically in this deregulated environment it's up to to the airline to decide the return the requirement for any given fare. In general, the cheaper the price the more restrictions including often a fairly narrow window for use, whereas full fare tickets are essentially without restriction and can be exchanged or refunded, making them effectively good forever (or as long as the airline is in business.)
Here are some sources of cheap tickets to Belize, but again you'll have compare restrictions and validity dates.
