US-Bangla Airlines, Bangladesh's largest private carrier, plans to place an order for leased aircraft valued at $4-5 billion within the next 60 days, according to a report by New Age BD.

The order would represent a substantial commitment for a carrier that has built its position in South Asia's domestic and regional markets. At that valuation, the deal would rank among the largest single aircraft commitments by a Bangladeshi operator, and its scale points toward widebody or large narrowbody acquisitions rather than the regional turboprops and smaller jets that anchor much of the airline's current operation.

The decision to source the aircraft through leasing rather than direct purchase is consequential. A $4-5 billion portfolio spread across lessors would give US-Bangla access to capacity without the capital outlay and delivery-slot commitments of a firm OEM order, while shifting residual-value and remarketing risk to the lessors. It also signals that the airline expects to secure near-term delivery positions, since lessors can often place aircraft from existing order books faster than manufacturers can offer production slots.

The 60-day timeframe sets a hard deadline for the carrier to finalise aircraft types, lessor counterparties and delivery schedules. Deals of this magnitude typically require board approval, lessor credit assessments and, in Bangladesh's regulatory environment, sign-off from the civil aviation authority on fleet induction plans.

US-Bangla has not disclosed which aircraft types it intends to lease, how many units the $4-5 billion would cover, or the delivery timeline. The valuation, however, frames the scale of ambition: even at the lower bound, the figure implies a multi-aircraft programme capable of reshaping the airline's network reach beyond its current domestic and short-haul regional routes.

For manufacturers and lessors, an order of this size from a South Asian carrier would add a new source of demand in a market where traffic growth continues to outpace capacity additions. For US-Bangla's competitors in the region, the prospect of a fleet infusion of this scale within two months raises the pressure on their own fleet decisions.

The airline now faces the task of converting a stated intention into signed documentation. Whether the order closes within the 60-day window will depend on lessor negotiations and financing arrangements that have not yet been detailed.
