A Mobile Boarding Pass is a digital version of a traditional boarding pass that travelers can access on their smartphones. It is typically provided by airlines through their official apps or via email after check-in. This pass contains essential information such as the passenger's name, flight number, departure time, and gate information. Using a mobile boarding pass offers convenience, as it eliminates the need for printed paper passes. Travelers can simply scan the QR code or barcode at security checkpoints and boarding gates. Many airlines, including Delta Air Lines and American Airlines, support this feature, making air travel more efficient.
