Mobile boarding passes, which use a two-dimensional barcode, were introduced Thursday for passengers departing on domestic flights from Chicago's O'Hare International Airport. On Monday, mobile boarding passes will be offered as an option for customers departing on domestic flights from Los Angeles International and John Wayne Orange County airports as well.
The mobile boarding pass program is being rolled out in partnership with the U.S. Transportation Security Administration. If successful in trial cities, it could be extended to
additional U.S. airports in the coming months.--Nina M. Lentini
