Misfiled Fares
HA, as a policy, does not file nor intend to offer/file tickets priced at zero or near zero. Essentially, such fares do not make any economic sense. We have introduced warning mechanisms to try to prevent such occurrences; however, occasionally fares such as these mistakenly get loaded into computer reservation systems that are not controlled by HA. Agents/customers should be aware that in these circumstances they are not allowed to ticket at these fares and HA will not honor fares of zero or near zero value. In the event a zero or near zero fare is ticketed inadvertently, HA will void such ticket and may choose to waive, in its sole discretion, certain rules or restrictions of existing published fares as a gesture of good will.
