Dallas / Fort Worth International Airport became the latest airport to allow Canadian and American passengers to use the Mobile Passport App. The app allows users skip the line at US airports for Customs and Border protection and go straight to an express lane.
After downloading the app, users scan their passport, take a selfie and fill out details of where they have been. Then, after entering the info, passengers get a QR code good for 4 hours that they show the express lane attendant.
This app is also available for use at Atlanta, Chicago, Miami, San Francisco and Seattle .
