For 14 years, Air Zimbabwe has been promising passengers a direct flight back to London. Governments have changed, Boeing 787 Dreamliner acquisitions have been announced and quietly shelved, and deadlines have slipped - most recently, a June launch date set by Mutapa Investment Fund chief executive John Mangudya passed without a single ticket being sold. But a new target date of 1 July now has an operational mechanism behind it that previous announcements lacked: a Spanish airline handing over its aircraft, its crew, its maintenance obligations and, crucially, its insurance.
The arrangement, an Aircraft, Crew, Maintenance and Insurance (ACMI) agreement with Madrid-based long-haul carrier Plus Ultra Líneas Aéreas, is the quiet but critical enabler of what would be one of the more significant African aviation relaunch stories of the year. Under the deal, Plus Ultra will deploy either an Airbus A330-200 or A340-300 - both capable of operating nonstop between Harare's Robert Gabriel Mugabe International Airport and London Gatwick - while flights operate under the Air Zimbabwe brand and commercial identity. The ACMI arrangement is contracted to run for 13 months.
For UK insurance professionals, the significance of the "I" in ACMI is worth understanding. Under a standard ACMI wet-lease arrangement, the lessor - in this case Plus Ultra - retains full operational control of the aircraft and provides comprehensive insurance coverage as part of the package. This includes hull insurance covering physical damage to the aircraft, liability insurance for third-party claims, and third-party cover, ensuring that the lessee can operate the service without independently sourcing or holding its own aviation insurance - something that would represent a significant barrier for a cash-constrained carrier like Air Zimbabwe.
ACMI insurance coverage typically includes hull damage, third-party liability claims, and often war risk, meeting global aviation insurance mandates. That last element is particularly relevant given the current insurance market environment. Aviation war risk pricing has remained sharply elevated since the escalation of Middle East hostilities earlier this year, with WTW's Q2 2026 Airline Insurance Market Renewal Outlook warning that "widespread rating increases should be expected" and capacity on routes touching elevated-risk airspace having contracted materially.
For Air Zimbabwe, attempting to source independent war risk and hull insurance as a national carrier with a historically troubled operational record and no long-haul fleet would have been extraordinarily difficult and expensive. The ACMI model sidesteps that problem entirely - transferring the financial risk of hull insurance and liability away from the lessee, and placing it squarely on Plus Ultra's established insurance programme.
Plus Ultra Líneas Aéreas is a Spanish carrier based at Madrid-Barajas, operating transcontinental services between Spain and Latin America with a fleet of seven Airbus A330 aircraft, certified under IOSA and IEnvA standards, and combining scheduled long-haul operations with flexible charter and ACMI solutions for airlines, tour operators and institutional partners worldwide.
In addition to regular scheduled flights to destinations including Bogotá, Cartagena, Lima, Malabo and Caracas, charter and ACMI services play an important role in the carrier's business model. Previous ACMI operations have included flying for SATA Azores Airlines on transatlantic routes and for Polish tour operators on Caribbean services. The Air Zimbabwe arrangement would mark the airline's entry into the sub-Saharan African market.
The carrier is not without controversy. Plus Ultra received a €53 million Spanish government rescue loan in 2021, justified on the grounds that it operated strategic long-haul routes connecting Spain with Latin America and parts of Africa, though the decision drew criticism from opposition parties and civil groups who questioned the company's chronic losses and the prominent role of Venezuelan investors in its ownership structure. A criminal investigation into the bailout was closed in 2023 after a judge found no evidence of wrongdoing.
Efforts by Zimbabwean media to obtain comment from Air Zimbabwe and the Mutapa Investment Fund on the reported ACMI agreement were unsuccessful, with officials declining to comment and describing the announcement as premature. That note of caution is understandable given the history: similar announcements were made in 2023, 2024, and earlier in 2026, with none producing an actual scheduled service - a fact noted sharply by Zimbabwean observers.
For insurance professionals, the Air Zimbabwe case illustrates why ACMI arrangements have become an increasingly common tool for national carriers seeking to re-enter markets for which they lack suitable aircraft or the insurance credentials to operate independently.
ACMI leasing allows an airline to focus solely on the commercial aspects - ticket sales and branding - while the lessor handles the operational package including insurance. For a carrier in Air Zimbabwe's position - lacking serviceable wide-body aircraft, operating under scrutiny from UK and European airworthiness regulators, and with limited balance sheet capacity to absorb insurance costs - this is not merely convenient; it is the only viable mechanism for a short-term route launch.
Under a standard ACMI arrangement, the lessor maintains insurance cover in line with contract and regulatory requirements, while the lessee sets the schedule, network and commercial strategy, sells seats, takes the revenue and demand risk, and pays for fuel, airport and handling fees. Air Zimbabwe, in other words, gets its London route without needing to go anywhere near the aviation insurance market itself.
As Insurance Business UK has previously reported on the aviation war risk market, the ability to access a fully insured aircraft through a wet lease arrangement has become a decisive competitive advantage in the current environment, with private market capacity constrained and pricing elevated across long-haul routes to and from regions perceived as carrying elevated risk.
The practical test is now straightforward. Until flights are loaded into global reservation systems, tickets are sold, schedules are published and an aircraft actually departs Harare for Gatwick, the announcement remains a promise. The Zimbabwean diaspora community in the United Kingdom - one of the largest in Europe, concentrated in areas including London, Birmingham and Manchester - has waited through fourteen years of similar promises, and the June deadline slipping past without comment from Air Zimbabwe's own management has done nothing to build confidence.
What is different this time is the specificity of the operational arrangement. A named ACMI partner, a named aircraft type, a named airport and a named launch date represent considerably more detail than previous declarations have offered. Whether Plus Ultra's insurance package, airworthiness standards and operational track record are sufficient to satisfy the UK Civil Aviation Authority's requirements for the service to commence is a question that will be answered by 1 July.
For the broking and underwriting community, the deal is a useful reminder that in a market where aviation insurance access has become structurally harder and more expensive, the ACMI wet-lease model - with its bundled, lessor-held insurance - is increasingly the instrument of first resort for carriers whose own insurance profile would otherwise make route launches prohibitively costly or practically impossible.
