Boeing delivered 67 737s, 13 787s and three 767s during the first quarter ended 31 March. The US airframer's output included three 767-based KC-46 tankers and one 737-800-based P-8 maritime patrol aircraft, Boeing's latest delivery data shows. Commercial deliveries in March comprised 24 Max jets and five 787s. In February, Boeing delivered 17 Max jets and seven 787s, following 25 Max jets and one 787 in January. Boeing booked 131 commercial aircraft orders during the January-March period. This includes orders from unidentified customers for 20 777X jets (placed in March), one 777 Freighter (in February), 10 Max jets (February), and another deal in January for three Max jets. Remaining orders booked in March came from American Airlines for 85 Max jets and from Ethiopian Airlines for eight 777-9s. Royal Brunei Airlines in February ordered four 787-9s.

Airbus has agreed to reschedule deliveries of new aircraft to Spirit Airlines initially intended to arrive in the second quarter of 2025 through the end of 2026, a deferment the US carrier says will save it $340 million over the next two years. The aircraft will instead be delivered in a 2030-2031 timeframe, the US airline states. Miramar, Florida-based Spirit's newly disclosed cash-saving efforts include the furloughing of approximately 260 pilots, effective 1 September, made necessary by fleet-size limitations caused by Pratt & Whitney geared-turbofan engine availability issues, along with the aircraft deferrals. Spirit and JetBlue Airways in early March terminated the merger agreement they agreed in July 2022, seven weeks after a US district court judge ruled in favour of the Department of Justice after it challenged the deal on competition grounds. The court's ruling blocked an influx of capital to Spirit from JetBlue. "This amendment to our agreement with Airbus is an important part of Spirit's comprehensive plan to bolster profitability and strengthen our balance sheet," Spirit chief executive Ted Christie states. "Deferring these aircraft gives us the opportunity to reset the business and focus on the core airline while we adjust to changes in the competitive environment." The deferral agreement with Airbus follows a compensation deal made with Pratt & Whitney affiliate International Aero Engines to receive a monthly credit in relation to the grounding of PW1100G-JM-powered Airbus A320neos. Spirit has on order 77 and 40 A321neos and A320neos, respectively. The deferral agreement with Airbus does not affect the number of Airbus aircraft Spirit has on order, the carrier says.

United Airlines is delaying the start of new Tokyo-Cebu and Newark-Faro routes as the carrier faces greater scrutiny from the US Federal Aviation Administration. The daily Cebu service was scheduled to start on 31 July but has been pushed back to the start of the northern winter scheduling season on 27 October. United's four-weekly services to Faro had been planned to start on 24 May but has now been pushed to the summer of 2025. "Impacted customers can receive full refunds or we will rebook their travel on one of our partner airlines without a fee," the airline states. The schedule change is a consequence of the FAA pausing some certification activities amid a safety probe into the airline. On 23 March, the regulator said that after "recent safety events" it was "increasing oversight of United Airlines to ensure that it is complying with safety regulations, identifying hazards and mitigating risk; and effectively managing safety". The FAA added at the time: "Certification activities in process may be allowed to continue, but future projects may be delayed based on findings from oversight."
