Delta Air Lines recently launched a partnership with Green Taxi Aerospace to develop an all-electric taxiing system that could save airlines $300,000 per aircraft annually through reduced fuel burn.

Delta Air Lines is partnering with Maeve Aerospace to advance the development of Maeve’s revolutionary hybrid electric aircraft for regional flights.

Delta's 757 fleet was also boosted by the 2008 merger with Northwest Airlines, which added 61 aircraft overnight. Thanks to having the same engine type as Delta's current fleet, Northwest's 757s made a smooth transition to strengthen the jet’s position in the fleet. The 757 was only made stronger as a pillar of Delta's fleet after the merger.

The MAEVE Jet is designed for regional flights and reduces fuel consumption and emission by up to 40% when using conventional jet fuel.

Delta Air Lines is replacing parts on more than 300 of its Airbus fleet to combat toxic fume leaks, which can be linked to serious health issues, including brain injuries, among both crew and passengers. The mass upgrades mark one of the boldest steps by a major U.S. airline to tackle a quietly escalating safety concern in modern aviation.

Delta Air Lines has been swapping out engines on 300-plus Airbus A320 jets since 2022 following reports of toxic air contamination affecting passengers and crew.

Delta Air Lines pilots and dispatchers didn’t look at all available weather information when they sent a plane into a damaging hailstorm in Italy in 2023, Italian transportation investigators ruled in a report published Thursday.

On Wednesday, two Delta regional planes collided at low speeds while taxiing at New York’s LaGuardia Airport. One of those planes was headed to Roanoke, carrying 28 passengers.
