Is it normal for airlines to ask for passport number?

No, you can make a booking without your passport details. Your passport number may, however, be needed at the time of online check-in.



Yes, it is completely normal and often legally required for airlines to ask for your passport number when booking an international flight. This information is part of the Advanced Passenger Information System (APIS), which airlines are mandated to share with the customs and border protection agencies of your destination country before the plane takes off. Providing this data early allows governments to pre-screen passengers for security risks and visa compliance. In 2026, many airlines now use "document scanning" technology within their apps to capture this info automatically. You will typically need to provide your passport number, expiration date, and country of issuance. While some airlines allow you to skip this step during the initial "seat reservation" phase, you will always be required to enter it before you can complete the online check-in process or receive a boarding pass. As long as you are booking through an official airline website or a reputable travel agency (OTA), your data is protected by strict encryption and privacy laws, making it a safe and essential part of modern global travel logistics.
