The Boeing 737 MAX 10 has become the aircraft that airlines want the moment the FAA finishes the paperwork. With the aircraft certified on October 20, 2026, the manufacturers order book of more than 1,555 firm commitments spread across 30-plus customers now carries real weight. This ranking sticks strictly to firm orders, leaving options and purchase rights aside, because an option is a conversation while a firm order is a commitment. Delta Air Lines and Pegasus Airlines both sit at 100 aircraft, which means six airlines occupy the five top positions. The gap between the carrier at the top and the ones below it says as much about fleet strategy as it does about buying power.
United Airlines Holds The Largest 737 MAX 10 Order With 167 Aircraft
United Airlines sits at the top of the table with 167 firm orders for the 737 MAX 10, a figure disclosed in its June 2026 regulatory filing. That count stands clear of every other named airline buyer and makes United the single largest identified customer for the type. Its history with the aircraft is longer than anyone else’s. United became the launch customer in June 2017, at the Paris Air Show, by converting 100 existing 737 MAX orders into the larger variant. Boeing confirmed at the time that the airline would be the largest single customer for the jet, and nearly a decade later the carrier has held that position.
The logic behind United’s early bet was straightforward capacity efficiency. At 185 to 210 seats in a typical two-class layout, the MAX 10 lets the airline move more passengers through congested hub slots without stepping up to a widebody. The 230-passenger maximum and roughly 3,100 nautical mile range also give United room to fly the type across its domestic network and into select international routes where a 757 once did the work.
Ryanair Commits To 150 Boeing 737 MAX 10s In Its Record Order
Ryanair’s agreement, announced on May 9, 2023, covered 300 aircraft in total, split into 150 firm orders and 150 options. At the time it was the largest aircraft order in the Irish carrier’s history, and the firm half alone puts it second in this ranking, behind only United. Deliveries are scheduled between 2027 and 2033, giving Ryanair a six-year window to absorb the type into one of Europe’s busiest short-haul networks.
The configuration tells you everything about how Ryanair intends to fly the jet. The airline plans a 228-seat layout, consistent with its high-density, low-fare model and its relentless push to drive unit costs down. Roughly half of the aircraft will replace older 737NGs, while the rest will fuel traffic growth. Ryanair has tied the order directly to its ambition of carrying 300 million passengers annually by March 2034, a target that would be impossible without an aircraft of this size and efficiency. If all 150 options are exercised, its commitment could double to 300 airframes, though this ranking counts only the 150 firm jets.
American Airlines Orders 115 Boeing 737 MAX 10s Through New Builds And Conversions
American Airlines announced its first MAX 10 order on March 4, 2024, committing to 115 aircraft through a blend of new purchases and fleet reshuffling. The deal paired 85 newly ordered MAX 10s with the conversion of 30 737 MAX 8s that were already sitting in American’s Boeing order book. That distinction matters: the 30 conversions added no new metal to the manufacturer’s backlog, they simply moved an existing commitment up to a larger airframe. The resulting firm total of 115 places American third in the ranking, ahead of Alaska and behind Ryanair.
Boeing also confirmed 75 options as part of the agreement. If American exercises all of them, its potential commitment climbs to 190 aircraft, but those remain future possibilities rather than confirmed orders. For American, the MAX 10 offers a way to add seats within the 737 family it already operates, avoiding the training and maintenance costs of introducing a separate type. The airline framed the deal as part of a wider fleet modernization push, replacing older equipment with more efficient jets across its domestic network.
Alaska Airlines Places Its Biggest Ever Order At 105 Boeing 737 MAX 10s
Alaska Airlines announced 105 firm 737 MAX 10s on January 7, 2026, the largest aircraft order in its history and a statement of intent from a carrier that had long kept its fleet plans conservative. The package also included five Boeing 787 widebodies and rights to purchase another 35 MAX 10s, extending the airline’s delivery stream through 2035. That 35-jet purchase right is flexibility, not commitment, so it stays out of the count.
The timing raised eyebrows. Alaska signed for the jet before the FAA had certified it, a move that reflected confidence in the program and the airline’s urgency to lock in capacity and delivery slots. The MAX 10 keeps commonality with the 737s already flying at Alaska, cutting pilot training and spare-parts complexity while adding seats per departure. The five 787s in the same agreement support the carrier’s international ambitions, pairing a long-haul widebody with a high-capacity single-aisle for domestic feeder traffic.
Delta Air Lines And Pegasus Airlines Share Fifth Place With 100 Boeing 737 MAX 10s Each
Delta Air Lines ordered 100 737-10s in July 2022 at the Farnborough International Airshow, with options for another 30. The order slots into Delta’s drive to refresh its single-aisle fleet and respond to passenger demand, and the airline has said the MAX 10 will be 20% to 30% more fuel-efficient than the retiring aircraft it replaces. Delta has been careful to keep the options separate from the firm commitment, giving it room to scale up if demand justifies it without inflating its current order book.
Pegasus Airlines matched Delta’s figure with 100 firm aircraft announced on December 19, 2024, alongside options for 100 more that could lift its total commitment to 200. The Turkish low-cost carrier wants the jet for fleet modernization and network expansion, with deliveries scheduled to begin in 2028. The aircraft also arrives against the backdrop of Boeing’s certification campaign, which included nearly 1,000 test flights and more than 2,000 flight hours before the FAA signed off.
Where Alaska committed early and American blended conversions into its total, Delta and Pegasus bought clean firm aircraft with sizeable options attached. The result is a ranking in which the last rung holds two very different airlines, one a legacy US carrier and the other a European-priced low-cost operator, both betting that the largest MAX will define their next decade of flying.
