Why Is Delta Stripping Engines From Brand‑New Airbus Jets in Europe?

(EUROPE) Delta Air Lines is stripping American-made Pratt & Whitney engines from brand new Airbus jets parked in Europe and sending only those engines back to the United States 🇺🇸. The move, which has accelerated through the summer of 2025, serves two aims at once: it keeps more of Delta’s existing fleet flying during an acute engine shortage, and it helps the airline dodge steep import taxes tied to U.S.-EU trade tensions.

A 10% tariff currently applies to European-built aircraft imported into the U.S., and that levy is set to climb to 30% on August 1, 2025 under policies associated with President Trump. By removing engines in Europe and shipping just those parts to the U.S., Delta is practicing a narrow form of tariff avoidance while dealing with regulatory delays that have left newly built jets undeliverable for now.

The core tactic: engines as movable assets

Delta’s workaround hinges on a simple gap in the rulebook: U.S.-manufactured engines do not face the same import duties as complete European-built aircraft. The airline has new Airbus A321neo jets sitting idle in Europe, in part because of seat certification delays and broader certification steps that are not yet cleared for U.S. operation.

The engines attached to those aircraft can be repurposed immediately, placed on older A320neo family jets sitting grounded in the U.S., and returned to service without the same regulatory roadblocks. Industry watchers say the practice is rare for brand new airplanes, but the combination of tariff risk and a severe engine shortage has pushed Delta to act now rather than wait for politics or paperwork to catch up.

Tariffs drive an uncommon workaround

At the center of this strategy lies a fast-rising tax burden:

• Current tariff on European-built aircraft: 10%
• Planned increase on August 1, 2025: 30%

For Delta, importing a completed A321neo from Europe after that date could cost millions more per aircraft. By contrast, transporting U.S.-made Pratt & Whitney turbofans off those Airbus jets and bringing the engines into the country alone avoids that bill—engines as components are not being hit with the same duty.

Delta’s chief executive, Ed Bastian, has been blunt: “We are not planning on paying tariffs for aircraft deliveries.” He noted that discussions are active in Washington and that he hopes for a resolution allowing deliveries to continue without penalty. Beyond that comment, the company has declined to share more operational details about the engine transfers, showing how sensitive and fluid the situation remains as the tariff clock runs down.

The airline argues it is acting within the rules while protecting operations and customers; analysts call the tactic a legal, narrow version of tariff avoidance that keeps planes flying and cash inside the business during uncertain trade policy.

The trade backdrop is hardening. U.S.-EU friction over large civil aircraft has been building since 2024, and the tariff line on European-built planes has become a direct cost for U.S. carriers that shop in Toulouse and Hamburg. Delta’s approach uses the existing framework to its advantage: engines are American-made and duty-free; airframes built in Europe draw a tariff at the border.

Certification delays and fleet impact

Regulatory friction compounds the pressure. New aircraft must clear several steps before joining a U.S. airline’s fleet, including seat certification and final approvals. These can take time even in stable periods. With the calendar ticking toward a higher tariff rate and with fresh jets not yet eligible to fly for Delta, the value of the engines attached to those planes changes.

• Engines become movable assets that can rescue grounded aircraft in the U.S. today.
• Airframes, by contrast, become temporary liabilities—worth less if imported at a penalty and still months away from revenue service.

Delta’s stock reacted to these risks: shares fell more than 3% after reports detailed the engine removal plan and the tariff exposure around upcoming deliveries. Still, the airline reaffirmed its 2025 profit guidance and reported Q2 earnings per share of $2.10—above expectations—on revenue of $15.51 billion, which came in below estimates.

Engine shortages and maintenance reality

Even without tariffs, Delta would face a real maintenance challenge: a shortage of serviceable Pratt & Whitney engines has grounded older A320neo family aircraft in the U.S., squeezing schedules and raising maintenance costs.

Key points:

• Shortage stems from supply chain troubles and longer-than-expected shop visits.
• New engines are not arriving fast enough to fill the gap.
• Engines on brand new Airbus jets in Europe become a lifeline when repurposed.

Cannibalizing new jets for parts is rarely seen on this scale, especially for aircraft that have yet to fly a single U.S. revenue hour. But airlines measure success by utilization—how many hours planes are airborne generating revenue. In this environment, an engine sitting on a delayed A321neo overseas is often more useful when powering a U.S.-based A320neo tomorrow morning.

Technicians and planners treat this as triage:

1. Inspect engines on parked aircraft
2. Match serviceable engines to grounded planes that can be reactivated fastest
3. Complete paperwork and shop checks to reinstall and return aircraft to service

Engine manufacturers, including Pratt & Whitney, continue to work through backlogs, but production realities mean airlines must plug gaps themselves.

Fleet metrics and order book

Delta’s fleet position highlights the stakes (as of July 2025):

• 65 aircraft inactive out of 1,007 total
• 274 planes on order, including:
  • 78 A321-200NXs
  • 67 A220-300s

In normal cycles, incoming deliveries refresh and expand capacity. In the current cycle, each new European-built aircraft risks a tariff hit if imported after the deadline. Delta’s engine-first strategy buys time while keeping current operations closer to full strength.

What this means for airlines, Airbus, and travelers

For Delta:
– Immediate benefit: more aircraft back in service without paying tariffs.
– Less need to cut flights, protecting revenue and routes.
– Company maintains the stance that the approach is temporary and tied to overlapping stressors.

For Airbus:
– Finished aircraft are waiting in Europe for U.S. buyers, carrying costs: space, working capital, and deviation from delivery timelines.
– The U.S. pipeline faces extra friction until trade talks change the tariff picture or U.S. certifications clear.

For travelers:
– Indirect effects may include fewer seats on peak days, higher fares on some routes, or tighter connections.
– Delta’s engine swaps help blunt that impact, but capacity is not unlimited.

Market reaction:
– Stock dropped more than 3% on the news.
– Delta’s Q2 EPS of $2.10 shows solid earnings despite operational strain; revenue of $15.51 billion missed estimates.

Trade negotiations are the biggest swing factor. A deal or temporary pause on aircraft tariffs would allow parked A321neos to enter service without penalty. If no deal appears and the rate rises to 30%, incentives for continued workarounds will grow across the industry.

Legal and policy context

CBP rules determine how parts and whole aircraft enter the country and what they cost at the border. Airlines, lessors, and manufacturers track those rules closely and plan shipments to fit within them.

Operational takeaways and traveler advice

• The situation is fluid: a single update from negotiators, a certification milestone, or a parts delivery can change the picture quickly.
• Delta has avoided detailed public disclosures on engine transfers to prevent lock-in to a moving target.
• Practical tip for travelers: check flight status and aircraft type closer to departure, especially on routes that have seen equipment changes this summer. Engine availability and shop capacity can still cause aircraft swaps or minor schedule shifts.

Wider implications and outlook

• This approach highlights how targeted tariffs reshape business practices: new Airbus jets built for U.S. customers can remain in Europe while their engines travel as freight to keep U.S. operations running.
• If talks produce a truce, parked airframes can be imported and engines returned to intended aircraft as Pratt & Whitney’s cycle improves.
• If the higher tariff sticks, similar workaround playbooks could spread among other U.S. carriers with European aircraft orders.

Delta has stayed tight-lipped beyond Bastian’s tariff stance, but public filings and fleet data offer a window into scale: 65 of 1,007 aircraft inactive in July, 274 in the order book, and a heavy mix of Airbus arrivals planned. The company is balancing maintenance needs, certification timelines, and tariff exposure while trying to keep schedules and crews stable.

Each engine shipped to the U.S. helps return one more aircraft to service and eases pressure on the schedule. Each airframe left overseas avoids a tariff bill that could climb to 30% within days. Those two facts explain why Delta is doing something so uncommon: dismantling brand new airplanes before they ever turn a wheel in U.S. service to meet the dual tests of trade policy and an engine shortage.
