903 oneworld Alliance

We speak with a oneworld Alliance VP about airline alliances in general, and oneworld in particular. In the news: a mid-air near miss at Atlanta, NTSB and families call on Congress to act on the DCA accident recommendations, a civilian plane crash and military GPS jamming, adaptive-cycle jet engines and sixth-generation combat aircraft, and the unleaded avgas transition plan.

Roger Blackburn serves as the Vice President – Commercial and Loyalty for the oneworld Alliance. He leads the commercial team and oversees corporate revenue, events, and alliance fare products, as well as the development of oneworld’s loyalty proposition. A member of oneworld’s leadership team for the past six years, Roger has led several key alliance initiatives, including the creation of oneworld’s first two branded lounges.

In our conversation with Roger, we learn about the value that airline alliances provide to the member airlines, and what value accrues to the flying public. We look at criteria for membership in an alliance, network fit, commercial value, and alliance governance, as well as loyalty programs and lounges.

For reference, here are the three major global airline alliances:

  • Star Alliance, founded in 1997 by Air Canada, Lufthansa, SAS, Thai Airways, and United.
  • oneworld, founded in 1999 by American Airlines, British Airways, Cathay Pacific, and Qantas.
  • SkyTeam, founded in 2000 by Delta, Air France, Aeroméxico, and Korean Air.

Two Delta Air Lines Jets in Mid-Air Near Miss at Atlanta Hartsfield as Air Traffic Control Direct Departing Aircraft into Path of Other Plane

This was a mid-air near-miss at ATL with two Delta Air Lines flights: Flight DL-1568 from Pittsburgh to Atlanta operated by a Boeing 737-900, and Flight DL-2472 from Atlanta to Rochester, New York, an Airbus A321.

The airport was experiencing weather delays, and controllers were working at full capacity to clear the backlog. Departures and arrivals were taking place on parallel runways. DL-1568 had been scheduled to land three hours earlier and was diverted to Chattanooga to wait out a storm.

The arriving flight 1568 elected to make a go-around after seeing a Frontier flight taking a long time to clear the runway. At the same time, departing flight 2472 was directed to turn and climb to the same altitude as the other Delta flight. A TCAS Resolution Advisory alarm sounded, and the aircraft came within 1,800 feet of each other.

NTSB Chair, Victim’s Families Call Upon Congress toTake Action on 50 Safety Recommendations After DC midair

It’s been a year and a half since American Airlines Flight 5342 and a U.S. Army Black Hawk helicopter collided near DCA, killing 67 people. Six months ago, the NTSB issued safety recommendations. NTSB Chair Jennifer Homendy and families of the victims want Congress to take action on the 50 open recommendations.

So far, Congress has failed to pass either the Rotorcraft Operations Transparency and Oversight Reform (ROTOR) Act or the Airspace Location and Enhanced Risk Transparency (ALERT) Act.

Statement from NTSB Chairwoman Jennifer Homendy on the open recommendations for the investigation of the January 2025 midair collision near Ronald Reagan Washington National Airport

In part: “Six months ago, we concluded our investigation and adopted our final report, issuing 75 findings and 50 safety recommendations, all of which must be implemented to prevent reoccurrence, yet we are no closer today to addressing many of the serious safety gaps that contributed to this terrible tragedy.

“Every day that passes without implementation of all 50 NTSB recommendations represents a continued and unacceptable risk to public safety.

“The National Transportation Safety Board provided a clear roadmap to improve aviation safety and reduce the risk of another catastrophic midair collision. Now it’s time for action that was promised months ago; we owe it to the victims, to the families who continue to grieve their loss, and to the millions of people who rely on the safety of our aviation system every day.”

A Civilian Plane Crashed in New Mexico. Was Military GPS Jamming To Blame?

On May 14, 2026, a Trans Aero MedEvac Beechcraft King Air 90 crashed in the New Mexico Capitan Mountains, killing four people. The NTSB’s preliminary report [PDF] stated that routine military GPS jamming exercises from White Sands Missile Range were active at the flight’s altitude and location. ADS-B was also degraded. The crew’s ForeFlight pre-flight package briefed the pilots on the jamming threat.

Air Force eyes next-gen engine ‘integration’ by 2030

Although no decision has been made, the Next Generation Adaptive Propulsion (NGAP) system could go into the F-47 Next Generation Air Dominance (NGAD) platform. Both Pratt & Whitney and GE Aerospace are developing NGAP prototypes which the Air Force intends to compete for future production. NGAP is designed to be platform agnostic and is a multi-billion-dollar program using adaptive-cycle jet engines for sixth-generation combat aircraft that change jet engine characteristics in flight, allowing more fuel-efficient cruising or increased thrust.

GE Aerospace and Pratt & Whitney (RTX) are the two competitors, building prototypes designated GE’s XA102 and P&W’s XA103. As of late July 2026, the program completed a pre-prototyping readiness review, with both contractors having met the Air Force’s design requirements, clearing the way to begin building and testing hardware.

‘Final’ Unleaded Avgas Transition Plan Released

The so-called “Version 1.0” of the 72-page FAA transition plan was released, updating a draft plan released earlier this year. The FAA says it’s keeping the 2030 target date for replacing 100LL with unleaded fuel.

Unleaded fuel takes center stage at AirVenture

The FAA took some of the comments received to heart, including communication and transparency. AOPA reports, “the FAA plans to release new versions of the transition plan after each phase. The agency also plans to publish two additional documents soon: an FAQ on unleaded fuel and a summary of the input received during the public comment period in early 2026.”

Four transition phases make up the plan:

  1. Authorizing fuels and doing comparison testing.
  2. Focus on unleaded fuels gaining market experience for the benefit of fuel producers, aircraft owners, fuel retailers, and others.
  3. Wide-scale transition, first in the Lower 48 by 2030.
  4. Followed by Alaska two years later.

Carlos Ozores is the Americas Aviation Lead for PA Consulting, a global firm that focuses on technology and innovation. Carlos addresses the key priorities for the U.S. aviation industry in 2026, including investing in airport infrastructure and addressing the industry labor shortage. He explains that U.S. airports have an estimated $170B capital requirement over the next five years to address airport infrastructure needs. Carlos tells us about the traditional sources to fund such projects, and what other sources could make up the shortfall.

We look at public-private partnerships, the Passenger Facility Charge, and monetization of airport assets such as terminal concessions, car parking, and real estate development. Also, utilizing data collected about passengers and the importance of airport stakeholder engagement.

Carlos tells us how the aging workforce is contributing to an industry labor shortage and leading to the loss of institutional knowledge. We talk about promoting the industry to the young generations, and issues such as pay, training, documented and repeatable work, quality of life, and labor relations.

Update: Air Traffic Controller Pay During Shutdowns Meets Resistance

The House Transportation Committee advanced a bipartisan bill (H.R.6086 – Aviation Funding Solvency Act) which “provides continuing appropriations to the Federal Aviation Administration (FAA) if (1) an appropriations bill for the FAA has not been enacted before a fiscal year begins, or (2) a law making continuing appropriations for the FAA is not in effect.” 

The “bill provides appropriations from the Aviation Insurance Revolving Fund at the rate of operations that was provided for the prior fiscal year to continue programs, projects, and activities that were funded in the preceding fiscal year. The FAA may use the balance of the fund, minus $1 billion. If the FAA determines that the amounts from the fund are insufficient to continue all programs, projects, or activities, then the FAA must prioritize compensation payments for employees of the Air Traffic Organization (e.g., air traffic controllers).”

However, Steve Womack (R-Ark.), chair of the House Appropriations Committee’s transportation panel, is critical of the legislation.

The Aviation Insurance Revolving Fund exists to cover war‑risk insurance claims for airlines participating in government programs such as the Civil Reserve Air Fleet (CRAF), when commercial insurance is unavailable or withdrawn. The balance was originally built up from premiums paid by airlines, but that premium program authority expired in 2014.

Because the fund has been largely unused for claims, investment earnings have grown it to roughly more than 2.6 billion dollars, significantly above what has historically been needed for CRAF-related claims.

The Abundance Problem: Why the FAA Has Spent 40 Years Modernizing Air Traffic Control—and Still Isn’t Done

Vincent E. Bianco III, an FAA Veteran and Senior Aviation Safety Consultant, describes why presidential administrations and Congresses have failed to adequately fund the FAA and modernize the ATC system. He draws on a concept from the March 2025 book Abundance: What America Gets Wrong About Capitalism and What We Can Do to Fix It, by Ezra Klein and Derek Thompson. Those authors describe how an institution, like the FAA, can become paralyzed by process, where well-intentioned rules accumulate. Each rule is logical by itself, but taken together, they end up stifling progress.

FAA Publishes Unleaded Avgas Transition Plan Daft

Section 827 of the 2024 FAA Reauthorization Act directs the FAA to facilitate a safe, timely, and orderly transition to unleaded alternatives while maintaining operational efficiency. The FAA released a Draft Transition Plan to Unleaded Aviation Gasoline – For Public Comment (January 2026, Version 1.0, 77 pages), which phases out 100LL fuel by 2030 in the contiguous United States, and by 2032 in Alaska. The FAA is seeking feedback from aviation professionals, specifically aircraft owners, pilots, and aviation stakeholders.

Boeing warned 15 years ago about a part problem at the center of UPS crash

The Air Current reports that in an investigation update, the NTSB noted “that cracking discovered in a spherical bearing assembly from the accident aircraft ‘appears consistent’ with an issue identified by Boeing almost 15 years ago.” The bearing assembly is part of the pylon aft mount bulkhead. That mount, and the forward mount bulkhead and thrust link assembly, attach the engine pylon to the wing.

“The NTSB’s preliminary report on the accident, released Nov. 20, revealed that on the left pylon aft mount bulkhead, the forward and aft lugs that house the spherical bearing assembly had fractured and separated. The spherical bearing’s outer race, which contains the ball bearing and allows it to move independently of the surrounding parts, had also fractured around its circumference.”

The 2011 Boeing service letter informed operators of bearing race failures on three different airplanes. A visual inspection of the part was added to the regular 60-month maintenance cycle. Also, Boeing recommended (but did not require) installing a new part design. Boeing determined that failure of the bearing race would “not result in a safety of flight condition.”

The NTSB is not saying this is the conclusive cause of the accident.

Hundreds of Aircraft Deregistered in FAA Move Against Trust Company

About 800 aircraft registered through U.K.-based Southern Aircraft Consultancy have been grounded after the FAA informed the company it did not meet U.S. citizenship requirements.  Those requirements allow a trustee firm to register aircraft in the US. Southern Aircraft Consultancy’s registration service allows non-American owners to maintain N-registrations on their planes. Southern Aircraft Consultancy says it intends to transfer its business to a U.S.-based company.

737 Diversion

Music artist, airline pilot, author, and piano technician Peter Buffington has released his second new studio album, 737 – Diversion by Speed Brake Armed.

“Recorded between late-night flights, hotel rooms, and restless studio time, 737 – Diversion captures the raw energy of sleepless nights, long-haul journeys, and the electric haze of life lived at 37,000 feet experienced by pilots. The 15-track project blends classic pop, worldly electronic, country, classic rock, and piano solo with introspective lyricism that pushes aviation-themed music into new territory. The music is family-friendly, yet captures the intensity of airline flying.”
