Commercial aviation is operating on two timelines at once. Boeing and Airbus are effectively sold out for much of the next decade, yet airlines still need aircraft available this summer. The gap between the planes that have been ordered and the planes that can actually fly has become one of the most consequential issues in the global economy. It is also the gap Demetrios Bradshaw built a company to address.

As founder and CEO of Aeras Aviation, Bradshaw leads a global engine and aircraft asset-management firm that sources, leases, repairs and remarkets the engines and assets airlines need to keep existing fleets in service while they wait years for new aircraft. Where manufacturers sell the future, Aeras operates in the present — managing spare engines, serviceable used parts and the remaining "green time" on mid-life powerplants so grounded aircraft can return to service this quarter rather than next year.

That timing matters because airlines are not just planning around demand; they are planning around what can physically be delivered, repaired or swapped into service. In that environment, asset management is no longer a back-office function but part of the operational plan that determines how much capacity can actually reach passengers.

Inside Aeras Aviation: how the company keeps global fleets flying

A backlog measured in decades

The numbers are striking. Airbus and Boeing together have a combined order backlog of roughly 15,800 aircraft, which is close to ten years of production at current build rates. Delivery slots for new narrowbody jets are now being quoted into the late 2030s and, for some configurations, into the 2040s. An airline that orders a new A320neo or 737 MAX today may not take delivery until a child born this year is finishing high school.

Hundreds of jets grounded and waiting

Even aircraft already in service are not all flying. A powder-metal flaw in Pratt & Whitney’s geared turbofan engine, which powers a large share of the A320neo family, has forced accelerated inspections of critical components. At its peak, the issue has grounded roughly 38% of the global A320neo fleet. Shop visits that once took 60 to 90 days are now stretching past 300 days, and the maintenance queue runs into 2027 and 2028.

"The most valuable asset in aviation isn’t the one on the order book — it’s the one that can fly next week," Bradshaw says. "Our entire business is built around keeping good assets in service and getting stranded ones back in the air."

The new economics of "green time"

For most of modern aviation history, an aircraft was treated as a depreciating asset: fly it, age it, retire it. The current squeeze has altered that pattern. Aircraft and engine values, along with lease rates, are at multi-decade highs as airlines and lessors work to keep older airframes in service years longer than planned. A serviceable engine has become a strategic instrument rather than a spare part, and the disciplined reuse of high-value assets has moved from the back office to the boardroom.

That shift also helps explain why maintenance capacity, parts availability and engine turns have become closely watched across the industry. When aircraft remain in service longer than planned, every extra day an engine spends in the shop can affect schedules, spare coverage and the flexibility airlines have to protect route networks.

"Every conversation about fares, capacity and route cuts eventually comes back to one question," Bradshaw notes. "Can you get the lift? If you can’t source the engine, the rest of the strategy is theoretical."

A bet on the United States

Bradshaw is now expanding Aeras into the U.S. market, with new logistics, storage and engine-management capacity announced earlier this year. The move also serves as a signal of demand in the aftermarket. His perspective is unusually broad: Aeras operates across the Middle East, Europe, Asia and Africa, and Bradshaw sits on the board of Air Botswana, giving him direct exposure to emerging-market aviation, where fleet growth and financing differ sharply from the environment in New York or London.

In 2026, four forces are colliding in commercial aviation: a sold-out production pipeline, a historic engine-maintenance backlog, fuel-price volatility and asset values at generational highs. Each would be significant on its own; together, they have reshaped the economics of flying. As manufacturers work through years of orders and Pratt & Whitney works through its maintenance queue, the companies that keep today’s fleets airborne are no longer a footnote to the industry — they are its pressure valve. Demetrios Bradshaw built one of those businesses, and from the center of the market, he has a clear view of where all four clocks point next.
