American Airlines tests face-scanning at DFW airport

American Airlines said Wednesday that customers with PreCheck can walk through security checkpoints at Dallas-Fort Worth International Airport with a face scan and phone app instead of showing their driver’s license or passport.

The airline said it intends to expand testing starting Wednesday at airports in Miami, Phoenix, Washington, D.C. and elsewhere later this year.

American is touting the service as a convenience factor that will help passengers get through security checkpoints more quickly. Privacy experts have expressed concerns about the personal information that people volunteer for convenience benefits, and how that information is used and stored.

At DFW airport, passengers will need PreCheck, a quick-screening service sold by the Transportation Security Administration, and American Airlines’ mobile app to use facial recognition technology.

Delta Air Lines and JetBlue Airways have used biometric technology for boarding at other airports.
