Princess Cruises’ Greenland sailings do not appear to have a clearly published “Greenland sales open” date in the results I could verify, but Princess’s 2026 Wave Season sale ran from December 9, 2025 through February 16, 2026, and its 2027 Europe/Northern Europe program was announced in January 2026 with voyages going on sale shortly after. That suggests Greenland-related inventory would most likely open around the same general schedule as other Europe/Northern Europe deployments, but I can’t confirm a specific Greenland date from the information available.

What is confirmed

  • Princess launched its 2026 Wave Season “Come Aboard Sale” on December 9, 2025.
  • That sale ran through February 16, 2026.
  • Princess announced a large 2027 Northern Europe program in January 2026.

Best practical read

  • If you’re trying to book a Greenland itinerary, the safest expectation is that openings happen with Princess’s broader Europe/Northern Europe rollout rather than on a separate, clearly advertised Greenland-only date.
  • In cruise booking terms, these launches often appear in wave-season windows or shortly after itinerary announcements.

How to verify fast

  • Check Princess’s current Europe and cruise-deals pages for newly released itineraries.
  • Watch for “now open for sale” wording on Princess announcement posts and press releases.
  • If you have a specific year in mind, that year matters a lot here because Greenland availability can change from one deployment to the next.

TL;DR: I could confirm Princess’s broad 2026 sale timing and 2027 Europe rollout, but not a separate official Greenland sales-open date.
