Pakistan blocks airspace for Russian fuel flight

Pakistan blocked its airspace on September 24 for a Russian aircraft carrying nuclear fuel for Bangladesh, delaying a shipment meant to arrive that day.

Officials said Pakistan cited technical issues; Bangladeshi officials said the shipment did not reach the country as scheduled.

Pakistan cites technical issues

The stoppage requires the operator to consider alternative routings or ground transfers, which would add flight time and require fresh overflight clearances from transit states. That process typically increases transit time and costs for sensitive cargoes.

The delay complicates logistics for Bangladesh's nuclear programme, which depends on timely fuel deliveries for reactor operation and maintenance. Longer interruptions could force operators to adjust refuelling or maintenance windows, potentially shifting technical schedules into the coming weeks.

If Pakistan reopens its airspace by October 1, the shipment could arrive within days; if restrictions persist past October 1, operators would likely need to reroute through other states, extending delays into October and adding regulatory steps.
