Cruise check-in is no longer a paperwork-heavy process completed at the port. For P&O Cruises guests, the mobile app acts as a digital travel companion, allowing passengers to manage check-in details, travel documents, health declarations, and boarding preferences well before embarkation day. However, many travelers complete check-in early and later realize they need to make changes.
This guide explains how to edit your check-in on the P&O Cruises app, what can and cannot be changed, and how to avoid common issues. The guidance is based on publicly available operational practices, maritime passenger regulations, and digital travel management standards used across major cruise lines.
The P&O Cruises app is designed to centralize passenger data while complying with international maritime security, immigration, and health regulations. Editing check-in information is possible, but only within defined limits.
When you check in using the app, the system securely stores multiple categories of data required for travel authorization and shipboard operations.
This includes:
Full legal name as shown on travel documents
Date of birth
Nationality
Gender (where required for border control)
These details are transmitted to port authorities and immigration systems, which is why accuracy matters.
Passengers may upload:
Passport or government-issued ID details
Emergency contact information
Health declarations or questionnaires if applicable
Some of this data becomes locked once validated by backend systems.
Editing check-in details is straightforward when changes are permitted. Timing and data type determine what can be modified directly.
Before making changes, you must locate your active booking within the app.
Follow these steps:
Open the P&O Cruises app and sign in using your booking credentials
Select your upcoming cruise from the dashboard
Tap the “Check-in” or “My Cruise” section
Review the status showing “Completed” or “In progress”
If the check-in window is still open, editable fields will appear.
Once inside the check-in section, editable fields are clearly marked.
You can usually edit:
Contact phone number
Email address
Emergency contact
Travel preferences such as arrival time slots
After editing:
Review all changes carefully
Save and confirm updates
Wait for the system confirmation message
Changes sync automatically, but it may take a short period to reflect across all app sections.
Not all check-in details are editable due to security and compliance requirements.
Certain data fields are restricted once verified.
Typically locked fields include:
Passport number after validation
Full legal name if already submitted to authorities
Date of birth linked to immigration records
Based on publicly available information, there is no confirmed data on this being overridden inside the app once final validation occurs.
If the app blocks edits, human assistance is required.
You should seek support if:
Your name does not match your passport
Your passport has been renewed after check-in
A medical or accessibility requirement was entered incorrectly
Support teams can reopen check-in or apply backend corrections after verification.

Seasoned cruisers follow simple habits to avoid issues:
Complete check-in only after finalizing travel documents
Double-check spelling against your passport
Save screenshots of confirmations
Reopen the app a few days later to verify data accuracy
These practices reduce embarkation delays and last-minute stress.
Cruise apps handle sensitive personal data and operate under international maritime data protection standards.
Passenger data is:
Encrypted during transmission
Stored in compliance with passenger manifest regulations
Shared only with authorized port and health authorities
This structured approach aligns with global travel safety frameworks used across the cruise industry.
Before sailing, confirm:
All editable details are correct
Boarding pass or QR code is visible in the app
Notifications are enabled
App is updated to the latest version
Completing this checklist ensures smooth terminal entry and boarding.
