Quark Expeditions upgrade eligibility
Whether a Quark Expeditions booking can be upgraded depends on a few factors. Eligibility is shown when you enter your booking reference and last name on Quark Expeditions's upgrade page — but here's what generally determines it.
What affects eligibility
These are the common factors that determine whether an upgrade offer appears on your booking:
- ·Fare class — deeply discounted and some promotional fares are often excluded; mid-tier and flexible fares are typically eligible.
- ·Timing window — upgrades usually open weeks before departure and close 24–48 hours before.
- ·Stateroom availability — the higher stateroom must have space.
- ·Route / sailing — not every route or departure is configured for upgrades.
- ·Booking structure — group bookings and some complex itineraries may be excluded.

Why don't I see an upgrade option on my Quark Expeditions booking?
