Is the Cathay Pacific online check-in 24 or 48 hours?

Cathay Pacific allows online check-in starting 48 hours before the scheduled departure time of your flight. This convenient service is available through their official website and mobile app, and it remains open until 90 minutes before departure. However, if you are traveling to or from the United States, online check-in becomes available only 24 hours before departure due to additional U.S. security regulations.

When you check in online, you can select or change your seat, add your frequent flyer number, and get your boarding pass electronically. This helps you save time at the airport and head straight to the bag drop or security check if you are not checking in luggage. For passengers without checked baggage, this can make the airport experience much smoother and quicker.

If you're flying on a codeshare flight operated by another airline, Cathay Pacific’s online check-in might not be available. In such cases, you will need to check in on the partner airline’s website or directly at the airport. It's also important to note that some special service requests, such as traveling with pets or requiring wheelchair assistance, may require airport check-in even if online check-in is technically available.

Cathay Pacific also offers the option to receive a mobile boarding pass, which can be saved on your phone or printed at home. For certain destinations, however, you may still be required to collect a physical boarding pass at the airport due to local immigration rules.

To ensure a smooth journey, it’s a good idea to check in as early as possible within the allowed window. This gives you a better chance of selecting your preferred seat and resolving any travel issues well in advance of your flight.
