Commercial aviation is running two clocks at once. On one hand, Boeing and Airbus are effectively sold out for the better part of a decade. On the other hand, airlines need to put passengers in seats this summer. The gap between the two — between the planes the world has ordered and the planes it can actually fly – has become one of the most consequential stories in the global economy. It is also the gap Demetrios Bradshaw built a company to fill.

As founder and CEO of Aeras Aviation, Bradshaw runs a global engine and aircraft asset-management firm that sources, leases, repairs and remarkets the engines and assets airlines need to keep existing fleets aloft while they wait years for new aircraft. Where the manufacturers sell the future, Aeras trades in the present — the spare engine, the serviceable used part, the “green time” left on a mid-life powerplant that lets a grounded jet fly again this quarter rather than next year.

A backlog measured in decades

The numbers are staggering. Airbus and Boeing are sitting on a combined order backlog of roughly 15,800 aircraft — close to ten years of production at current build rates. New narrowbody delivery slots are now being quoted into the late 2030s and, for some configurations, the 2040s. An airline that orders a fresh 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 the aircraft already in service aren’t all flying. A powder-metal flaw in Pratt & Whitney’s geared turbofan engine — the powerplant on a large share of the A320neo family — has forced accelerated inspections of critical components. At its worst the issue has parked roughly 38% of the global A320neo fleet, with shop visits that once took 60 to 90 days now stretching past 300, and the maintenance queue running 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 a depreciating asset: fly it, age it, retire it. The current squeeze has bent that curve. Aircraft and engine values, along with lease rates, are sitting at multi-decade highs as airlines and lessors fight 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.

“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 American market, with new logistics, storage and engine-management capacity announced earlier this year — a deployment of capital that doubles as a read on aftermarket demand. His vantage point is unusually wide: Aeras works across the Middle East, Europe, Asia and Africa, and Bradshaw sits on the board of Air Botswana, giving him a direct line into emerging-market aviation, where fleet growth and financing look very different from the picture in New York or London.

Four forces are colliding in commercial aviation in 2026: a sold-out production pipeline, a historic engine-maintenance backlog, fuel-price volatility and asset values at generational highs. Each alone would be a story; together they have rewritten the economics of flying. As the manufacturers work through a decade of orders and Pratt & Whitney works through its queue, the businesses that keep today’s fleets in the air are no longer a footnote to the industry — they are its pressure valve. Demetrios Bradshaw built one of them, and from a seat in the middle of the deals, he has a clear view of where all four clocks point next.
