Hawaiian Airlines flight attendants, represented by the Association of Flight Attendants-CWA, on 14 March reached a tentative agreement on a contract extension through February 2028. This extension includes "continued pay increases, retirement improvements, better profit sharing, and a strong foundation to build upon as negotiations for a Joint Collective Bargaining Agreement (JCBA) begin this month", AFA-CWA said in a 14 March press release. "This provides a second bite at the apple for all Hawaiian and Alaska flight attendants claiming their share of the benefits of the merged airline." The contract extension includes three pay raises, inclusion in the Alaska Air Group profit sharing program, and scheduling improvements, AFA-CWA adds. The extension tentative agreement will be sent to Hawaiian Flight Attendants for a vote that closes on 17 April.

An engine on an American Airlines Boeing 737-800 caught fire while the aircraft was taxiing to a gate at Denver International on 13 March. American flight 1006, bound for Dallas/Ft Worth International, had been diverted to Denver after the crew reported engine vibrations, says the US Federal Aviation Administration. The 737-800 departed Colorado Springs and landed safely at Denver at 17:15 local time. "After landing and while taxiing to the gate, an engine caught fire and passengers evacuated the aircraft," the FAA says, adding that it will investigate the incident. Denver International airport says in an X post that all passengers were safely evacuated from the aircraft, adding that 12 people were transported to local hospitals with minor injuries. American has confirmed that after landing safely and taxiing to the gate at Denver International, "flight 1006 experienced an engine-related issue", adding: "All 172 customers and six crew members deplaned". Data indicates that the 13 March flight was operated with a 737-800 (MSN 31139) that was built in 2012 and is leased by the US major from AerCap. MSN 31139 was delivered to American in February 2012. The same month, it was sold to an entity named SkyFunding Limited and leased back to American by AerCap. The current lease is set to expire in February 2026.

The US Federal Aviation Administration is permanently restricting non-essential helicopter operations around Ronald Regan Washington National airport and eliminating helicopter and fixed-wing mixed traffic. The move comes after the National Transportation Safety Board (NTSB) asked the FAA to permanently prohibit helicopter operations near the airport when runways 15 and 33 are in use, and to designate an alternative helicopter route. The FAA notes in a 14 March update that it is permanently closing Route 4 between Hains Point and the Wilson Bridge and evaluating alternative helicopter routes as recommended by the NTSB. It adds that it is prohibiting the simultaneous use of runways 15/33 and 4/22 when helicopters conducting urgent missions are operating near DCA. "If a helicopter must fly through the airspace on an urgent mission, such as lifesaving medical, priority law enforcement, or Presidential transport, the FAA will keep them specific distances away from airplanes," it says. Furthermore, the FAA is limiting the use of visual separation to certain Coast Guard, Marine and Park Police helicopter operations outside the restricted airspace. The FAA says it is "continuing its analysis of airports that have high volumes of mixed traffic". That includes an assessment of the eight cities where it has charted helicopter routes: Boston, New York, the Baltimore-Washington area, Detroit, Chicago, Dallas, Houston and Los Angeles, some of which have multiple airports. The administration is also assessing the US Gulf Coast, including offshore helicopter operations. "The FAA will have corrective action plans for any risks that are identified," it says. "To make us more predictive, we are using machine learning and language modeling to scan incident reports and mine multiple data sources to find themes and areas of risk."
