Tunisair Expands Capacity with an Additional ACMI Airbus A320

Tunisia’s national carrier has added an Airbus A320 operated under an ACMI arrangement by Portuguese charter and wet-lease specialist White Airways. This additional external capacity, reported by NewsAero, highlights the persistent fleet strain at Tunisair, even as the Tunisian government has set an ambitious target for restoring the airline’s active fleet by year-end.

An ACMI Solution That Reflects Structural Fragility

The arrival of this additional Airbus A320, operated under an ACMI (Aircraft, Crew, Maintenance, Insurance) arrangement by White Airways, does not reflect a network-growth strategy but rather an operational adjustment to compensate for constraints on Tunisair’s own fleet. Under this model, a third-party carrier supplies the aircraft, crew, maintenance, and insurance, allowing Tunisair to add capacity quickly without tying up capital or engaging in a lengthy acquisition or dry-lease process.

The choice of White Airways — a Lisbon-based Portuguese carrier long specialized in charter operations and third-party aircraft leasing — reflects a common industry practice, particularly during periods of peak seasonal demand or reduced availability of an airline’s own fleet.

An Active Fleet Under Pressure for Several Years

This operation must be viewed within the broader context of Tunisair’s ongoing fleet difficulties. Tunisia’s Transport Minister, Rachid Amri, has set a target of 21 active aircraft by the end of 2026, compared with roughly ten operational aircraft in recent months — a gap that underscores the scale of the fleet-restoration effort under way as part of the carrier’s rescue and restructuring plan.

On paper, Tunisair operates a relatively homogeneous fleet built around the Airbus A320 family (including A320neo units) plus two A330-200s for long-haul services. But the gap between registered fleet size and actually available aircraft points to challenges common across the North African aviation sector: prolonged heavy-maintenance groundings, spare-parts supply difficulties, and cash-flow pressure limiting maintenance capacity.

The Economic and Strategic Stakes of Wet-Leasing

ACMI arrangements generally carry a higher cost than in-house operation over the medium term, but they offer valuable flexibility to maintain flight-schedule reliability and avoid cancellations that could damage a carrier’s commercial reputation. For a national airline engaged in a restructuring plan, preserving operational reliability is a matter of credibility — not only with passengers, but also with lenders and investors closely monitoring execution of the rescue plan.

This type of arrangement also raises a financing question: every ACMI flight hour adds to the operating costs of an already financially strained carrier, raising doubts about the sustainability of this solution should it extend beyond a temporary fix.

Impact on Industry Stakeholders

For the Tunisian state, Tunisair’s majority shareholder, this episode underscores the urgency of accelerating the renewal and return to service of the carrier’s own fleet — a precondition for the success of the restructuring plan announced for 2026. For investors and lenders, the growing recourse to ACMI capacity is a metric worth watching, as it signals the actual pace of the airline’s operational recovery. For the regional leasing and wet-lease market, this deal confirms rising demand across North Africa for flexible capacity solutions, at a time when several legacy carriers are struggling to keep their fleets at optimal availability levels.

Outlook

The Tunisair case illustrates a broader trend among African national carriers undergoing restructuring: growing reliance on ACMI and wet-lease contracts as a buffer against aging or under-maintained fleets. While this approach can secure short-term operations, it cannot substitute for structural fleet renewal. Tunisair’s trajectory over the coming months — between actually meeting its 21-aircraft target and prolonged dependence on external capacity — will serve as a meaningful test of the credibility of the rescue plan launched by Tunisian authorities.
