It was my understanding that changes to ticketed points can be made after ticketing for USD125 and that there is no fare reassessment unless the first sector changes. However, rule 16(a)(1)(b) says:
Changes to ticketed points are permitted at a charge of USD125.00 per transaction. If the fare level has increased since ticket issuance, the difference between the old and new fare will also be charged. If the fare level has decreased since ticket issuance, no refund will apply.
Is my understanding wrong such that ticketed point changes prior to the first departure, whether the first sector or other sectors, requires a reassessment of the fare?
