The cicle fares are mileage based (like GE and most competing RTW-type fares). OWE is continent based, not mileage, making it better value (cost per mile). For many trips the circle fares are more convenient and usually much cheaper than the equivalent point-to-point fare. The circle pacific fare is described at http://www.oneworldalliance.com/prod...fm?ObjectID=28
