TL;DR: Cathay Cargo will relocate its Mumbai freighter service to Navi Mumbai International Airport (NMIA) from 3 August 2026, becoming the first international airline to make the shift. The move is driven by a complete suspension of dedicated freighter operations at Chhatrapati Shivaji Maharaj International Airport (CSMIA) from August 2026 through May 2027. Infrastructure works at CSMIA – including apron reconstruction, runway rehabilitation, and taxiway development – triggered the transition. NMIA’s purpose-built cargo terminal has Phase 1 capacity of 800,000 tonnes, with 10 freighter stands and 29 hectares reserved exclusively for cargo, scalable to 2.5 million tonnes by 2032.

Cathay Cargo has set 3 August 2026 as its transition date to Navi Mumbai International Airport, making it the first international carrier to publicly commit to shifting dedicated freighter operations away from Mumbai’s main airport. The Hong Kong-based carrier operates a three-times-a-week summer freighter service to Mumbai. That frequency stays unchanged. Only the airport changes.

The operational trigger is well-documented. CSMIA’s Apron G, which handles all dedicated freighter traffic, has deteriorated to the point where full pavement reconstruction is now unavoidable. Because CSMIA’s layout leaves no room for a temporary freighter apron while passenger gates remain in use, a full suspension of dedicated freighter services becomes the only viable option for the duration of the works, scheduled between August 2026 and May 2027. Cathay is first to move. Others are close behind.

Why CSMIA’s Freighter Suspension Is a Bigger Deal Than It Looks

Freighters accounted for nearly 31% of CSMIA’s total cargo throughput in the most recent reporting period. That is not a marginal slice of the operation. DHL, FedEx, Qatar Airways, and Cathay Cargo rank among the top freighter operators at the airport. Air France runs two weekly freighter services between Paris and Mumbai. Air France and Lufthansa Cargo are among the carriers still finalising their transition plans. When CSMIA suspends freighter operations, a significant share of India’s air cargo volume will need an alternative hub.

This is not the first attempt to shift freighters out of CSMIA. MIAL, the operator of CSMIA – an airport managed under the Adani Airport Holdings Limited (AAHL) umbrella – first targeted an August 16, 2025 start date for the suspension. IATA pushed back hard, raising concerns about permanent slot withdrawal. CSMIA confirmed to The STAT Trade Times that the matter was resolved amicably and the slots were reinstated. The second attempt, backed by documented infrastructure necessity, is gaining airline acceptance.

Diplomatic Friction and the US-India Air Transport Agreement

The relocation has attracted attention beyond the freight industry. The US Department of Transportation wrote to India’s Ministry of Civil Aviation in March 2026. The letter warned the move could breach the US-India Air Transport Agreement. FedEx is the only American cargo airline currently operating out of CSMIA, which gives the US position a specific commercial edge.

An Adani spokesperson described the move as “a phased and limited realignment of select international freighter operations rather than a wholesale, permanent shift.” The diplomatic tension has not stopped the transition. Cathay has confirmed its date. The infrastructure timeline at CSMIA leaves little room for further delay.

What NMIA Brings to the Table – and What Still Needs Work

NMIA’s infrastructure was designed with long-term cargo volume growth in mind. The airport sits roughly 40 kilometres from CSMIA. Its dedicated cargo terminal has Phase 1 capacity of 800,000 tonnes, scalable to 2.5 million tonnes by 2032. Ten freighter stands are available. Cold-chain infrastructure is in place. A single 3,700-metre runway capable of handling wide-body freighters up to Airbus A380 scale serves the airport. NMIA is targeting nearly 18 weekly freighter flights as operations scale up – compared to a single confirmed operator at launch. International passenger services at NMIA are set to begin on 15 July 2026, with Air India Express launching the first international route to Abu Dhabi.

The infrastructure is ready. The operational challenges are more human. Critically, the skilled cargo workforce – ground handlers, customs brokers, logistics staff – is still concentrated near CSMIA. Forwarders routing cargo through Mumbai from August 2026 need to factor these realities into their planning now, not later.

Cargo Solutions Network Perspective

India is growing fast as an air cargo origin. Electronics, pharmaceuticals, perishables, engineering goods, and e-commerce are all driving volume. Cathay’s commitment to Mumbai – same frequency, different airport – signals that the trade is worth protecting. But for freight forwarders managing Mumbai-origin shipments, the CSMIA-to-NMIA transition creates real operational questions. Transit times between the two airports, ground handler availability, and customs processing speeds at a newly activated facility all need answers before August.

Forwarders who quote Mumbai routes need current, accurate rate data across the carriers making this shift. If you are building quotes for Hong Kong, Europe, or Middle East connections via Mumbai, the carrier and terminal details are changing. At Cargo Solutions Network’s quoting portal, freight professionals can access and validate rates across carriers and routing options – airport-to-airport (A2A) or door-to-door (D2D) – with full routing flexibility across carriers and modes. When markets shift, speed to quote matters.

Frequently Asked Questions

When does Cathay Cargo move to Navi Mumbai International Airport?

Cathay Cargo’s Mumbai freighter service relocates to NMIA on 3 August 2026. The three-times-a-week flight frequency remains unchanged. Only the operating airport changes from CSMIA to NMIA.

Why is CSMIA suspending freighter operations?

CSMIA’s Apron G – the dedicated freighter apron – has deteriorated beyond serviceable condition and must be fully reconstructed. Separately, new taxiways are being built alongside runway rehabilitation works. The suspension runs from August 2026 through May 2027. With no spare apron available during passenger operations, the airport cannot accommodate freighters for the duration of the works.

Which other airlines are moving freighter operations to NMIA?

Air France and Lufthansa Cargo are among the international carriers still finalising their transition plans. Cathay Cargo is the first to confirm a firm date.

What cargo capacity does Navi Mumbai International Airport have?

NMIA’s dedicated cargo terminal has Phase 1 capacity of 800,000 tonnes. It has 10 freighter stands, cold-chain infrastructure, and 29 hectares reserved exclusively for cargo. Capacity is scalable to 2.5 million tonnes by 2032.

Is the NMIA relocation permanent?

The current relocation is described as temporary, tied to the CSMIA infrastructure works running through May 2027. An Adani spokesperson described it as “a phased and limited realignment of select international freighter operations rather than a wholesale, permanent shift.” Whether all carriers return to CSMIA after reconstruction is an open question.
