Passengers may upgrade their cabin class at any point before departure, subject to availability in the higher class on the same itinerary and departure date. Upgrades are processed through the Pelorus Voyages account portal or by contacting bookings support. The upgrade charge is the price difference between the original cabin class fare and the new cabin class fare at the current rate (not the original rate if pricing has changed since booking), minus any upgrade discount applicable to the passenger's loyalty tier: 10 percent for Navigator tier, 20 percent for Pathfinder tier.

Upgrades paid using Orbital Points must be completed at least seven days before the departure window opening. Within seven days of departure, upgrades are possible but must be paid by credit card, debit card, or Orbital Credits — Orbital Points cannot be applied to upgrades within the seven-day window. This cutoff applies regardless of loyalty tier.

When a cabin class upgrade is confirmed, the passenger's mass allowance increases immediately to the allowance of the new class. A passenger upgrading from Pioneer (12 kg) to Navigator (18 kg) gains 6 kg of additional personal mass allowance; this additional allowance can be used for items checked at the Earth launch terminal on departure day, subject to the standard baggage procedures. Equipment rental credits associated with the new class are also available from the date the upgrade is confirmed.

Cabin class downgrades after booking are not permitted. Passengers wishing to move to a lower cabin class must cancel the current booking (with applicable cancellation fees) and create a new booking in the desired class.

Itinerary changes — changing from one voyage type to another (for example, from IPS to GST) — are treated as a cancellation of the original booking and a new booking at the current price. Cancellation fees apply to the original booking based on how far in advance of the departure date the change is made. Itinerary changes made within 14 days of the original booking date may qualify for the free cancellation window on the original booking.

Add-on purchases — excursions, the gondola descent, the Extraction Coverage add-on, and equipment rental credits above the class allowance — can be added or modified up to 48 hours before departure. After 48 hours before departure, no new add-ons can be purchased and existing add-on bookings cannot be cancelled for refund.
