EasyJet plans to implement its APU-Zero project at Milan Malpensa airport following a successful trial in September 2024. The carrier says the initiative involves turning off aircraft Auxiliary Power Units (APUs) during turnarounds and replacing them with electric and hybrid Pre-Conditioning Air Units (PCAs) that connect to the airport's Fixed Electrical Ground Power. The project, developed in collaboration with TCR, PCA manufacturer Guinault, and ground handler Menzies Aviation, with support from SEA Milan airports, aims to reduce fuel consumption, carbon emissions and noise pollution during ground operations. During the trial, which involved 57 aircraft at Milan Malpensa's Terminal 2, EasyJet demonstrated that the PCAs could effectively provide heating, cooling air and power to stationary aircraft. Easyjet director of sustainability Lahiru Ranasinghe states: "This trial, part of our operational efficiencies workstream, resulted in fuel and emissions savings and a reduction in noise, without affecting our operation. This is yet another small but important step that contributes to our broader decarbonisation journey and is an excellent example of an initiative that provides both environmental and business benefits." The airline estimates the full implementation will save approximately 1,150 tonnes of fuel annually, equivalent to 3,600 tonnes of CO2. The rollout will involve deploying 16 PCA units at Milan Malpensa, with six units being added in March, six more in April, and the final four in May 2025.

The US National Transportation Safety Board (NTSB) has asked the US Federal Aviation Administration to permanently prohibit helicopter operations near Ronald Reagan Washington National airport when runways 15 and 33 are in use, and to designate an alternative helicopter route. Not doing so poses "an intolerable risk to aviation safety by increasing the chance of a midair collision", the NTSB says in an "urgent safety recommendation report" released in tandem with a preliminary report on the 29 January fatal collision of a US Army Sikorsky H-60 Black Hawk helicopter and a PSA Airlines MHIRJ CRJ700 regional jet (operating flight 5342 for American Airlines) on final approach to Washington National's runway 33. The collision killed 67 passengers and crew on both aircraft. The NTSB notes in the urgent safety report that preliminary findings suggest that the existing separation distances between helicopters transiting the Route 4 helicopter corridor and aircraft landing on runway 33 are insufficient.

Ticket sales from the UK to USA have slowed sharply since early November, with bookings flipping from being significantly ahead of a year earlier to notably behind, Cirium's advance-bookings data indicates. From London airports Heathrow, Gatwick, Stansted and Luton to New York's JFK, Newark, La Guardia and Stewart, advance-bookings data for June travel shows a relatively strong bookings trend from the start of September until early November. In the week to 21 October, for example, there was nearly a quarter more daily bookings made from London to New York for June travel than a year earlier. Cirium does not publish the number of bookings made, within its advance-bookings data – only the changes. However, for over a month in the period since early November, daily bookings from the UK appear to have grown more slowly than normally. They rose 22% in the week to end-December, versus 7 November, where a year earlier they had risen 64% over the same timeframe. Since then, bookings this year have risen by 107%, against an 135% increase in 2024. Currently, there are around 14% fewer daily bookings being made for June travel from London to New York this year than in 2024, the data shows. This means that sales for June travel have flipped from being stronger in the period up to early November to being slower afterwards. Searching the same data for bookings between London and Los Angeles shows a similar trend. Daily sales to the Californian city for June travel were 62% higher in the week to end-December than in the week to 7 November 2024, against a corresponding increase of 84% a year earlier. It is impossible to specify a cause of the trend. The change does coincide with the re-election of US president Donald Trump, but many other factors could be having an influence, including the general economic landscape, pricing, the timing of holidays, and whether consumers are choosing to book earlier or later in the cycle. A look at the same booking trends between the London airports and other destinations indicates that bookings activity outside the USA seems comparatively stable. Daily sales from London to Toronto Pearson for June travel, for example, rose 49% in the period from 7 November to end-December 2023, and 45% a year later. Likewise, bookings to Bangkok showed an 80% rise for June travel between the weeks ending 7 November and 31 December 2023, and an 81% rise a year later. A similar trend is visible in Europe. From London to Rome, sales for June travel were in 2023 up 19% in the week to end-December compared with 7 November. In 2024, the corresponding percentage increase matched exactly, and the number of daily sales was extremely similar to a year earlier. This appears to indicate that the fallback in sales from the UK is limited to the US market. Advance-bookings data tracks sales from the three largest global distribution systems, and not direct sales with airlines. It thus captures around 40% of the market.
