The Princess Cruises app—also known as the MedallionClass app—has changed the way guests prepare for their cruise, making the entire check-in process faster, more flexible, and much easier to manage. Whether you need to update your travel documents, revise emergency contact information, or adjust your onboard preferences, the app allows you to make changes at nearly any point before embarkation. Understanding how to edit your check-in is essential for ensuring a smooth boarding experience and avoiding delays at the port.
The editing tools inside the MedallionClass app are designed to give guests complete control over their pre-cruise setup. Most sections can be updated instantly, while others may lock closer to the sailing date. Knowing exactly what can be edited—and when—helps you complete all requirements on time.
The app divides the check-in process into categories that you can modify individually. Each category stores information that Princess Cruises needs before you board.
Your name, date of birth, and legal identification details are usually locked unless these changes are part of a valid correction or an approved name-change request. However, you can still update certain optional details such as preferred contact information and general profile elements.
This includes the details from your passport, government-issued ID, or visa. If you entered the wrong expiration date or need to add the information for a new passport, the app allows you to update it. Documentation must match what you present during boarding.
The MedallionClass app requires you to upload a security photo used at ports, onboard venues, and the embarkation terminal. You can retake or replace this photo anytime before check-in is finalized.
If you need to change your credit card, add a new card, or switch the card responsible for a family member’s charges, the app lets you adjust this at any time. Guests often update this right before traveling.
While the app is flexible, certain elements cannot be edited once finalized.
Your sailing date, itinerary, and stateroom assignment are fixed. If you must change any of these, you need to contact Princess Cruises or your travel agent.
Once reservations are linked, they typically stay connected unless you manually remove or unlink them. Some guests prefer to keep linked parties together for dining, excursions, and onboard chats.
Editing your check-in on the Princess Cruises app is simple, but you need to follow each step carefully to make sure your updates save correctly. The following instructions work for both iOS and Android versions of the app.
After opening the app, sign in using the same email and password you used when booking your cruise or creating your Princess account.
Once logged in, navigate to “Journey View,” which displays all active bookings. Select the reservation you want to edit.
Inside your trip details, you’ll find a “Check-In” option. This area contains all the editable categories.
The app shows a status bar for each section, such as:
Personal Info
Travel Documents
Security Photo
Emergency Contacts
Payment Info
Travel - Arrival & Departure Details
Click into any category you want to update.
Each category may have different fields depending on your cruise destination and personal travel needs.
If you need to revise passport details:
Tap Travel Documents
Select Edit Document
Enter updated information
Save the changes
You may be prompted to re-upload a scanned image or photo of your passport.
You can replace your photo if you don’t like the lighting or angle:
Tap Security Photo
Select Retake Photo
Follow the photo guidelines displayed on screen
Save
To update card information:
Tap Onboard Account
Remove the old card
Add the new payment method
Assign each traveler to the correct card
Some edits require confirmation through a verification step before being accepted. For example, documentation updates may prompt a reminder to bring the physical document to the port.
Princess Cruises uses two color-coded lanes at embarkation:
Green Lane – Fully complete check-in
Blue Lane – Missing required steps
After editing your information, the app should reflect a Green Lane status. If it does not, double-check that you’ve completed all mandatory fields.
Small details can dramatically affect how smoothly your embarkation goes. Following these tips helps prevent issues at the terminal.
While some changes can be made at the terminal, it’s best to finish the process in advance. Incomplete check-in leads to longer lines and possible delays.
Changes involving passports or visas may require you to upload a photo of the document. Having your passport nearby simplifies this.
Many guests accidentally enter incorrect dates, which can flag their reservation for review. Double-check that all dates match your physical documents exactly.
If you're traveling with family or friends, make sure everyone’s check-in progress matches. Inconsistent information may cause certain guests to fall into the Blue Lane.
Everyone must complete his or her own check-in, even when reservations are linked.
Edits are allowed up to a certain point before sailing, but making last-minute updates may lock you out of some sections.
Occasionally, guests experience technical issues or encounter locked sections in the app. Here’s what to do if you run into difficulties.
Common fixes include:
Logging out and back in
Restarting the app
Updating the app to the latest version
Switching between Wi-Fi and mobile data
Some categories freeze 72 hours before sailing. If that’s the case, only Princess staff can make adjustments.
If the app still won’t allow changes, the support team can manually update your reservation details. You can also ask your travel agent to assist.
