In 2026, you generally do not need to print a paper boarding pass if you check in online, as digital boarding passes stored on smartphones are the industry standard at nearly every major airport. Most airlines allow you to use their mobile app or add the pass to your digital wallet (Apple Wallet or Google Wallet) to be scanned at security and the gate. However, there are still critical exceptions where paper remains a necessity. Some international destinations (such as certain airports in Morocco, Turkey, or India) still require physical "validation stamps" on a printed pass for security reasons. Additionally, if you are flying a budget carrier like Ryanair and have not checked in via their app, or if you are traveling to a country that requires a "document check" at the counter, you may be forced to print a pass. It is always wise to keep a screenshot of your digital pass in case of poor connectivity and, for peace of mind on long international journeys, a single printed backup in your carry-on is still a recommended "fail-safe" against dead batteries or tech glitches.
