In 2026, while most airlines offer digital boarding passes via their apps, you often still need to visit a check-in counter for international flights, which may result in a physical pass. This is primarily for document verification (passports, visas, and entry authorizations like ETIAS or ESTA). Many airlines will not allow you to generate a mobile boarding pass until an agent has physically or digitally verified that you have the legal right to enter your destination country. Furthermore, some airports in regions like parts of Asia, Africa, and the Middle East still require a stamped physical boarding pass to clear immigration or security. Even if you have a digital version, it is "best practice" in 2026 to either print a backup or ensure you have your confirmation slip ready, as some gate readers or local authorities may not accept a phone screen. Always check the specific "Check-in" email from your airline, as it will explicitly state if a mobile pass is valid for your specific international route.
