Green Lane is the highest level of "OceanReady" status for guests on a Princess Cruises vacation, signifying that they have completed 100% of their pre-cruise requirements. To achieve Green Lane status, a guest must use the Princess MedallionClass app to complete their travel profile, upload a security photo, enter their passport information, and select a "Method of Payment" for onboard expenses. The most distinguishing factor of the Green Lane is that you have your Princess Medallion (the wearable device that replaces a room key) shipped to your home before you leave. When you arrive at the cruise terminal, "Green Lane" passengers enjoy the most streamlined embarkation process possible—often called "expedited arrival"—where you can skip the traditional check-in lines, have your documents quickly verified, and walk directly onto the ship. If you do not complete these steps or choose to pick up your Medallion at the terminal, you are placed in the Blue Lane, which requires a more traditional, and often slower, check-in process. In 2026, being "Green Lane" is the gold standard for a stress-free start to a Princess cruise.
