half-round-trip fare
1. (US/CA fares) Half of a round-trip fare. A one-way fare is never considered a half-round-trip fare. See also combinations.
2. (International fares) Half of a round-trip (Tag 2) fare or a one-way (Tag 1) fare doubled and halved. Half of a specified/published or constructed/unpublished round trip normal or special fare. Additionally, the one-way normal may be considered to be a half-round-trip normal fare. If a one-way special fare may be doubled to establish a round-trip special fare, the one-way special fare may be considered to be a half-round-trip special fare. A one-way Tag 1 fare doubled and halved may be considered to be a half-round trip-fare, but it is never considered to be a Tag 2 fare. A half-round-trip fare is never a one-way (Tag 3) fare that cannot be doubled. See also combinations.
