Whether you need a new boarding pass after a layover depends on how you checked in and whether your flights are on the same "itinerary" or booking. In 2026, if you are traveling on a single ticket with a major airline (like Delta, United, or Emirates), you will typically be issued all of your boarding passes at once—either as physical cards at the initial check-in counter or as a series of digital passes in your mobile wallet. In this case, you simply use the second pass for your connecting flight. However, if you are flying with two different airlines on separate tickets (a "self-transfer"), you will likely need to check in again at the transfer desk or via the second airline's app to receive a new pass. Furthermore, some international layovers require you to visit a "Document Verification" desk to have your visa or passport checked before a new boarding pass can be validated for the final leg. Always check your airline's app during the layover; if your gate number is updated, the digital pass will refresh automatically, but if it shows "See Agent," you will need to obtain a new physical pass.
