Aviation Capital Group LLC (ACG) and Japanese carrier Skymark Airlines (BC) have finalized lease agreements for seven Boeing 737-10 aircraft, with deliveries scheduled to begin in 2028.

Announced on July 20, 2026, at the Farnborough International Airshow, the agreement supports Skymark’s strategy to increase passenger capacity on domestic routes operating out of the highly slot-constrained Tokyo Haneda Airport (HND). The Boeing 737-10 is the largest variant in the 737 MAX family, offering the airline a higher-density configuration compared to its existing fleet.

Fleet Modernization and Capacity Growth

Skymark currently operates a fleet of 30 aircraft, consisting of Boeing 737-800s and Boeing 737-8s. According to fleet data reported by ch-aviation, the airline plans to configure the newly leased Boeing 737-10s with 207 seats. This represents an increase of 30 seats per aircraft over its current 177-seat Boeing 737-800 and 737-8 configurations.

The capacity increase is critical for Skymark’s operations at HND, where adding new flights is restricted by slot availability. Aviation Week reports that Skymark is offering 6.03 million seats across its domestic network during the summer 2026 season, representing a 0.4 percent increase year-over-year. The introduction of the larger Boeing 737-10 will allow the carrier to grow its passenger volume without requiring additional departure slots.

“For airlines serving high-density markets from slot-constrained airports, the ability to add capacity, improve efficiency, and maximize revenue opportunities is critical,” ACG Chief Executive Officer and President Thomas Baker stated in the July 20 press release.

Expanding Boeing 737 MAX Commitments

The ACG lease agreement builds on Skymark’s existing commitments for the Boeing 737 MAX family. Aviation Week notes that the carrier already holds firm orders directly with The Boeing Company for seven Boeing 737-10s, alongside a mix of orders and lease agreements for seven Boeing 737-8s. Skymark became the first Japanese airline to introduce the Boeing 737-8 into commercial service in May 2026, debuting the aircraft on the route between HND and Fukuoka Airport (FUK).

Skymark Airlines President and Representative Director Yoshihiro Miwa highlighted the operational benefits of the new aircraft.

“We look forward to operating the 737-10, which boasts the largest capacity in the MAX series, and welcoming even more passengers to enjoy the Skymark experience.”

The Boeing 737-10 is also expected to deliver improved operating economics. A May 2026 Skymark fleet presentation cited by ch-aviation estimated a 19 percent reduction in fuel costs per seat for the Boeing 737-10 compared to the older-generation Boeing 737-800.

Aviation Capital Group’s Farnborough Momentum

The Skymark deal marks the second major Boeing 737-10 placement announced by ACG in July 2026. On July 14, 2026, the lessor announced long-term lease agreements with Canadian carrier WestJet (WS) for 13 Boeing 737-10 aircraft.

The consecutive agreements underscore strong lessor demand for the largest MAX variant as airlines seek to maximize yield in constrained airport environments.

AirPro News analysis

We view Skymark’s decision to lease additional Boeing 737-10s as a pragmatic approach to the strict slot limitations at Tokyo Haneda Airport. By upgauging from the Boeing 737-800 to the 737-10, Skymark can add 30 seats per departure. This strategy mirrors a broader industry trend where carriers operating in congested hubs rely on larger narrowbody variants to drive growth when frequency expansion is impossible. Securing these airframes through a lessor like ACG provides Skymark with delivery certainty starting in 2028, insulating the carrier’s near-term growth plans from potential direct-from-manufacturer delivery delays.

Saudi Arabian startup carrier Riyadh Air (RX) has expanded its future widebody fleet by firming up an order for six additional Airbus A350-1000 aircraft at the Farnborough International Airshow on July 20, 2026. The agreement exercises purchase rights from a 2025 commitment for up to 50 airframes, bringing the airline’s total firm backlog for the European manufacturer’s largest twin-engine jet to 31 aircraft.

In a press release issued during the airshow, Airbus confirmed the transaction and noted that Riyadh Air will become the first operator of the A350-1000 in Saudi Arabia. The acquisition aligns with the carrier’s mandate to support the national Vision 2030 strategy, which targets serving more than 100 global destinations by the end of the decade.

Expanding the Airbus widebody footprint

The Airbus A350-1000 offers a maximum non-stop range of 9,700 nautical miles (18,000 kilometers), providing the operational capability required for Riyadh Air’s planned ultra-long-haul services. Airbus states the aircraft delivers a 25 percent advantage in fuel burn, operating costs, and carbon emissions compared to previous-generation widebody aircraft.

Riyadh Air Chief Financial Officer Adam Boukadida stated that the finalized order reflects continued confidence in the airline’s growth trajectory and the broader Saudi aviation sector.

“Increasing our A350-1000 commitment to 31 aircraft strengthens the foundation of our future network and supports our ambition to serve more than 100 global destinations by 2030 while delivering a premium guest experience,” Boukadida said.

Airbus Executive Vice President of Sales for Commercial-Aircraft Benoît de Saint-Exupéry added that the commitment highlights the aircraft’s efficiency and range. He noted the A350-1000 will play a central role in positioning Saudi Arabia as a leading international aviation hub. As of the end of June 2026, Airbus had recorded 1,595 firm Orders for the A350 family from 68 customers worldwide.

Concurrent Boeing 787 Dreamliner expansion

The Airbus finalization occurred alongside a separate widebody order placed with The Boeing Company. According to reporting by Al Arabiya, Riyadh Air also confirmed an order for 28 additional Boeing 787 Dreamliner aircraft at the Farnborough event on July 20.

This separate agreement introduces the Boeing 787-10 variant to the carrier’s fleet. Following the announcement, Riyadh Air’s total firm commitment for the Dreamliner family stands at 67 aircraft.

Riyadh Air Chief Executive Officer Tony Douglas told Al Arabiya that the introduction of the 787-10 and the expanded Dreamliner backlog marks another significant milestone in the airline’s journey toward its 2030 network goals. The carrier recently opened ticket sales for its initial overseas routes as it prepares for the launch of commercial operations.

AirPro News analysis

We view Riyadh Air’s dual widebody orders at Farnborough as a clear signal of the carrier’s aggressive timeline and robust capital backing. By splitting its high-capacity, long-haul requirements between the Airbus A350-1000 and the Boeing 787-10, the airline mitigates delivery risk in an era of constrained aerospace supply chains. Securing 31 firm A350-1000s and 67 Boeing 787s provides the necessary metal to rapidly scale a global network from scratch. However, the operational complexity of inducting two distinct widebody types simultaneously will require substantial training, tooling, and maintenance infrastructure investments prior to the Launch of commercial flights.

Indian low-cost carrier IndiGo and CFM International signed a Memorandum of Understanding (MoU) on July 20, 2026, for more than 1,000 LEAP-1A engines to power 510 Airbus A320neo Family aircraft. The agreement, finalized at the Farnborough International Airshow, represents the largest single order for LEAP engines in the manufacturer’s history.

The procurement completes the engine selection for IndiGo’s outstanding narrowbody order book and includes a long-term material services agreement. According to a press release issued by GE Aerospace, the deal also provides support for establishing a new engine maintenance, repair, and overhaul (MRO) facility for the airline. CFM International operates as a 50/50 joint venture between GE Aerospace and Safran Aircraft Engines.

Record-setting engine procurement

The MoU covers the power requirements for a specific segment of IndiGo’s future fleet. Reporting by Aviation Week indicates the order breaks down to engines for 135 undecided Airbus A320neos and 375 undecided Airbus A321neos. The airline currently operates more than 430 aircraft, with over 375 A320 and A321 Family jets already supported by CFM.

Incoming IndiGo Chief Executive Officer Willie Walsh, who officially assumes the role by August 2026, stated the LEAP engine’s reliability makes it the ideal choice to support the carrier’s scale and operational resilience.

“As IndiGo embarks on its next phase of growth towards becoming a truly global airline, we are delighted to extend our long-standing partnership with CFM International for the engines powering future deliveries of our Airbus A320/321neo Family aircraft fleet,” Walsh said in the company statement.

GE Aerospace Chairman and Chief Executive Officer H. Lawrence Culp, Jr. noted the engines are delivering up to twice the time on wing in hot and harsh operating environments compared to their initial entry into service.

Transitioning the narrowbody fleet

The massive LEAP-1A commitment finalizes IndiGo’s pivot away from the Pratt & Whitney PW1100G geared turbofan (GTF) engine. Aviation Week reported the airline previously faced the grounding of up to 75 aircraft due to GTF durability problems and powder metal defect issues.

IndiGo began its relationship with CFM in 2016 with a sub-fleet of Airbus A320ceo Family aircraft powered by CFM56-5B engines. The carrier deepened that partnership in 2019 by selecting the LEAP-1A for its initial batch of Airbus A320neo and A321neo aircraft. The July 20 agreement ensures the remainder of the airline’s narrowbody deliveries will utilize CFM propulsion.

AirPro News analysis

We view this 1,000-engine MoU as a definitive operational reset for IndiGo as it prepares for leadership under Willie Walsh. The carrier’s previous exposure to Pratt & Whitney GTF supply chain and durability constraints severely impacted capacity. By standardizing the remaining 510 A320neo Family deliveries on the LEAP-1A, IndiGo is prioritizing fleet availability and predictable maintenance intervals over a split-engine strategy. The inclusion of localized MRO support in the agreement also signals a maturation of India’s domestic aviation infrastructure, reducing the airline’s reliance on constrained global overhaul facilities.
