Delta Air Lines is launching a biometric screening program in Atlanta and Detroit in partnership with the Transportation Security Administration that aims to expedite the check-in and boarding process with facial recognition technology for travelers who hold passports and are members of Delta's frequent flyer program and the TSA's PreCheck program. At Hartsfield-Jackson Atlanta International Airport, Delta is opening an express lobby and baggage drop service exclusively for travelers eligible for the biometric program. "We want to give our customers more time to enjoy travel by unlocking simplified, seamless and efficient experiences from end to end," said Byron Merritt, Delta's vice president of brand experience design.

American Airlines has revamped its AAdvantage frequent flyer program, creating a system where participants earn and spend loyalty points, generated at varied levels based on air travel and purchases from partner companies. The most notable new feature treats all points the same, thereby allowing participants to theoretically earn elite status based on credit card and partner points.

Andrea Lusso, the airline's JetBlue's vice president of network planning, said the airline will "be going back to our roots and long-term plan again," with a focus on its routes in the Northeast and Florida.

Alaska Airlines is collaborating with ZeroAvia to develop a hydrogen-electric engine that can power a 76-passenger aircraft with a 500-mile range.

The House Homeland Security Committee has approved legislation that would require signs and instructions at US airports, as well as their website content, to be available in multiple languages. The proposal would also require the Transportation Security Administration to improve communications with people who have vision or hearing impairment.
