On Princess Cruises, being in the "Blue Lane" means your "OceanReady" profile is incomplete or missing key information required for a streamlined embarkation. To move into the preferred "Green Lane," you must complete all 10 pre-cruise steps in the Princess app, including uploading a photo, entering passport details, and selecting a boarding window. If you are in the Blue Lane in 2026, you will have to wait in a longer queue at the terminal so a staff member can manually verify your documents and issue your Medallion wearable. If you are in the Green Lane, your Medallion may have been mailed to your home, allowing you to walk directly to the security checkpoint. Essentially, Blue Lane represents "Standard Check-in," while Green Lane represents "Expedited Entry." Completing your profile 24 hours before sailing is the easiest way to turn your status from Blue to Green and start your vacation faster.
