When can I check in with the Royal Caribbean app? Is there a difference if I checked in via the website?

You can check in on the app beginning 45 days in advance and up to the morning of your sailing. App check-in provides several benefits over web check-in, such as less time spent in the terminal and more time on vacation. In the app, you will scan your passport, upload your security photo and answer the required health questions to receive your mobile boarding pass. The terminal agent simply verifies your travel documents and scans your mobile boarding pass.

Remember, you still need to bring your passport and other travel documents with you to the terminal check-in.
