Boeing and Partners Develop Sensors to Reduce Aviation Contrail Impact
Boeing, Honeywell, and University of Reading develop onboard sensors to measure humidity and help airlines avoid climate-impacting contrails.
This article is based on an official press release from Boeing. The original report is paywalled; this article summarizes publicly available elements and public remarks.
A new collaborative project involving Boeing, Honeywell, and the University of Reading aims to develop advanced onboard sensors to help airlines mitigate the climate impact of condensation trails, or contrails. The initiative targets a critical gap in aviation’s environmental strategy by focusing on non-CO2 emissions.
Funded by the Aerospace Technology Institute (ATI) and Innovate UK, the project seeks to create prototype water vapor sensors capable of measuring atmospheric conditions during flight. According to a Boeing press release, this data will improve weather forecasting and enable airlines to avoid specific atmospheric regions where persistent contrails are likely to form.
As detailed in the company’s announcement, Boeing will provide its engineering expertise to integrate the new sensors onto commercial aircraft and conduct real-world flight testing, moving the technology from the laboratory to the skies.
The Science and Strategy Behind Contrail Mitigation
Addressing the Non-CO2 Climate Impact
While the commercial aviation industry has heavily focused on reducing carbon dioxide emissions through sustainable aviation fuel and engine efficiency, researchers and airlines increasingly recognize that contrails significantly contribute to global warming. Contrails form when hot, humid engine exhaust mixes with cold, low-pressure air at high altitudes, creating microscopic ice crystals.
Most contrails dissipate quickly and have a negligible environmental effect. However, under certain atmospheric conditions, they persist and spread into cirrus clouds that trap heat radiating from the Earth’s surface. Boeing estimates that just 10 percent of flights are responsible for the majority of contrail-related climate impacts.
Overcoming Measurement Limitations
Currently, commercial aircraft lack the specialized equipment needed to accurately and frequently measure the specific humidity and temperature conditions that lead to persistent contrails. The new sensor project aims to fill this critical data gap by developing hardware that can be widely adopted across global airline fleets.
By deploying affordable and accurate water vapor sensors, the industry hopes to gather reliable atmospheric measurements. This data will not only enhance general weather forecasting but also allow flight dispatchers to route planes around ice-supersaturated regions, effectively preventing the formation of warming contrails before they occur.
Collaborative Roles in the Sensor Project
Industry and Academic Synergy
The project divides responsibilities among its three primary partners to accelerate the development and deployment of the new technology. Honeywell is leading the hardware design and integration, utilizing its specialized facilities in Yeovil, UK.
Boeing’s role focuses on the practical application of the technology, ensuring the sensors can be safely and effectively fitted to commercial airframes for real-world testing. Meanwhile, the University of Reading’s Department of Meteorology, which has researched aviation’s climate impacts for over three decades, will handle data analysis and contrail modeling.
Perspectives from the Partners
The initiative aligns with broader industry goals, including the UK aerospace sector’s commitment to achieving net-zero aviation and the ATI’s Non-CO2 Technologies Roadmap. Company leadership emphasized the importance of leveraging existing flight operations, which already collect data on winds, temperature, and turbulence, to gather new environmental metrics.
“We’re excited to work with ATI, Honeywell and the University of Reading on a new water vapour sensor, as humidity observations are essential,” said Dr. Tia Benson Tolle, Boeing Commercial Airplanes Product Development Sustainability Director.
Academic partners echo this sentiment, noting that high-quality humidity measurements are a critical component of future mitigation actions and will allow for the optimized use of aircraft equipped with these sensors.
AirPro News analysis
We view the development of specialized contrail sensors as a pragmatic step toward addressing aviation’s non-CO2 climate impacts. While alternative fuels and new engine designs offer long-term solutions, optimizing flight paths to avoid contrail formation could provide immediate environmental benefits using current-generation aircraft.
However, we note that the success of this initiative will depend on the widespread adoption of the sensors by commercial airlines and the seamless integration of the resulting data into daily air traffic management systems. Balancing contrail avoidance with fuel efficiency and airspace congestion will be the next major hurdle for the industry as it works toward comprehensive sustainability goals.

Alaska Air Group Unveils Lie-Flat Suites and Premium Cabins
Alaska Air Group introduces lie-flat suites on 737-10 MAX and 787 aircraft, a new Premium Reserve class, and expanded lounges by 2028.
Alaska Air Group has unveiled a sweeping overhaul of its premium cabin and lounge offerings, introducing lie-flat suites to its narrowbody fleet for the first time and establishing a unified premium strategy following its acquisition of Hawaiian Airlines.
Announced during the company’s 2026 Investor Day in Seattle on September 29, the investment introduces the “Aurora” and “Leihōkū” flagship experiences for Alaska Airlines and Hawaiian Airlines. In a press release, the company detailed plans to roll out a new “Premium Reserve” premium economy class and open expansive new lounges in Seattle and Honolulu, targeting a shift in revenue mix that aims to push premium revenues above 40 percent of total revenue by 2030.
Fleetwide cabin upgrades and lie-flat expansion
The introduction of the Aurora and Leihōkū suites marks a significant product evolution for both carriers, with cabin retrofits and new deliveries scheduled to begin in 2028. For Alaska Airlines, the Aurora product will bring 34 lie-flat suites to its Boeing 787 Dreamliner fleet. The updated Boeing 787-9 configuration will increase the aircraft’s total premium seating to 46 percent, up from 38 percent.
In a major shift for its domestic operations, Alaska Airlines will also install 12 lie-flat suites on at least 25 of its Boeing 737-10 MAX aircraft. This development brings true premium transcontinental capabilities to the Alaska Airlines narrowbody fleet, allowing the carrier to compete directly with legacy airlines on coast-to-coast routes.
Hawaiian Airlines will see its 24 Airbus A330 widebody aircraft retrofitted with 22 redesigned Leihōkū Suites. The upgrade will boost the premium seating footprint on the A330 fleet from 30 percent to 40 percent.
Alaska Airlines President and Chief Financial Officer Shane Tackett emphasized the strategic necessity of the upgrades in capturing high-yield traffic.
“We already have the scale and customer base, now we are making sure we have the right product for every trip our guests take. Aurora, Leihōkū and Premium Reserve close important product gaps across international, Hawaiʻi and premium transcontinental flying, giving us more ways to compete for high-value demand while preserving the distinct identity of the Alaska Airlines and Hawaiian Airlines brands.”
Introducing Premium Reserve and expanded lounges
Alongside the flagship suites, Alaska Air Group is launching Premium Reserve, a dedicated premium economy cabin designed to align the carriers with international long-haul standards. The new class will offer passengers 38 inches of seat pitch and 16-inch 4K OLED seatback screens.
The onboard investments are paired with a major expansion of the company’s ground facilities. A new 41,000-square-foot lounge complex is slated to open at Seattle-Tacoma International Airport (SEA) in late 2027. Shortly after, in early 2028, a 13,000-square-foot Hawaiian lounge will open in Terminal 1 at Honolulu (HNL). Alaska Air Group Chief Executive Officer Ben Minicucci stated that the Aurora and Leihōkū concepts are intended to raise the standard for comfort, dining, and service from the moment passengers arrive at the airport.
Integrating operations under Alaska Accelerate
The premium product overhaul is a cornerstone of the “Alaska Accelerate” strategic plan, which the company outlined to investors as it works to integrate Hawaiian Airlines. Alaska Airlines completed its $1.9 billion acquisition of Hawaiian Airlines on September 18, 2024. The merger combined Alaska’s primarily domestic narrowbody network with Hawaiian’s widebody international routes.
Through the Alaska Accelerate initiative, the company is targeting $1 billion in incremental profit by 2027, with $500 million expected to materialize from merger synergies. Following the acquisition, Alaska Airlines assumed Hawaiian’s Boeing 787 Dreamliner orders, integrating them into its own fleet expansion strategy while Hawaiian retained its Airbus A330 operations.
The company also announced the expansion of its Atmos Rewards loyalty program, which integrates HawaiianMiles and Alaska Mileage Plan to offer unified earning and redemption options across the combined global network.
AirPro News analysis
The decision to install lie-flat seats on the Boeing 737-10 MAX represents a fundamental shift in Alaska Airlines’ domestic strategy. For years, the carrier relied on standard domestic first-class recliners, effectively ceding the highest-yield premium transcontinental market to Delta Air Lines (DL), United Airlines (UA), American Airlines (AA), and JetBlue. By equipping its largest narrowbody aircraft with true suites, we see Alaska directly challenging the established coast-to-coast hierarchy and defending its Seattle hub against legacy incursions.
Furthermore, the introduction of the Premium Reserve class is a necessary maturation for the combined entity. As Alaska Air Group integrates Hawaiian’s widebody network and takes delivery of Boeing 787s, a true premium economy product is required to compete on international routes where a three-cabin configuration is the baseline standard. Pushing premium seating to 46 percent on the Boeing 787-9 indicates a strong confidence in long-term premium leisure demand, a segment that has remained resilient since the post-pandemic travel recovery.
