A Boeing 757-200PCF converted freighter leased from AerSale Corporation enters revenue service in October with Romanian cargo carrier Mister Air Transport, the first aircraft the airline will operate under its own certificate and crews.

Delivery ends Mister Air's reliance on wet-leased capacity from third-party carriers and shifts the carrier onto scheduled and ad-hoc freighter services targeting express e-commerce and parcel flows between Asia, the Middle East and Central and Eastern Europe.

Why a 757, and why now?

AerSale, a US-based aftermarket aircraft and engine supplier, positions the 757-200PCF as the operational sweet spot for Mister Air's "middle-mile" thesis. Long range and high payload let the carrier serve production and e-commerce gateways across Central and Eastern Europe without the unit-cost disadvantage of larger widebodies.

Craig Wright, AerSale's senior vice president and head of asset management, said: "The 757 remains one of the most capable and sought-after platforms in its segment, and this transaction reflects both the strength of that asset class and AerSale's ability to deliver flight-ready aircraft to operators pursuing ambitious growth."

What does the aircraft unlock commercially?

For shippers and forwarders, the move adds maindeck capacity on under-served lane segments where integrators and combination carriers traditionally dominated. Mister Air's parent, Łódź-headquartered AerCommerce, supplies an established cargo charter and brokerage customer base that the carrier will now serve directly.

Ireneusz Dylczyk, chief executive of Mister Air, said: "This Boeing 757-200PCF marks an important milestone in Mister Air's growth and the launch of our own flight operations. The 757's range and payload make it the ideal aircraft for our customers."

"AerSale proved to be a professional and responsive partner throughout the process," Dylczyk added. "This aircraft lays the foundation for the additional freighters we intend to introduce as we scale our network."

Where will the aircraft operate?

Mister Air holds a Romanian air operator certificate but runs flight operations from Łódź Władysław Reymont Airport (LCJ) in central Poland, a positioning choice that places the carrier inside a roughly 1,500-kilometre reach of most major CEE e-fulfilment hubs.

The deployment model splits the chain: AerCommerce sells and books the cargo, Mister Air flies it. Capacity booked through AerCommerce today sits with partner carriers; from October onward, a rising share moves on Mister Air metal.

What are the fleet and expansion plans?

The leased 757-200PCF is the first of more. Mister Air has stated plans to add additional freighters as the network scales, without disclosing delivery dates, conversion slots or further lease counterparties. The carrier's pitch to forwarders: scheduled frequencies on routes that have historically run only as ad-hoc charters.

For AerSale, the transaction supports a broader push to monetise 757 passenger-to-freighter conversion slots. The US lessor has previously secured additional B757 cargo conversion feedstock to feed operator demand.

What does it mean for the CEE air cargo market?

The middle-mile segment — connecting Asian and Middle Eastern gateways to CEE distribution centres — has grown with cross-border e-commerce volumes but remains thinly served by maindeck capacity. Mister Air's entry adds a dedicated narrowbody option between integrators and ad-hoc charter brokers.

The carrier's Romanian registration and Polish base also create tax and operational considerations for shippers booking capacity through AerCommerce, though the source material does not specify those structures.

Outlook

With the first 757-200PCF in revenue service this month and additional freighters on the drawing board, Mister Air's transition from charter-broker-backed flying to self-operated carriage sets a test for whether dedicated middle-mile maindeck capacity can win a durable share of CEE e-commerce flows.
