Bangladesh has barred budget carrier SpiceJet from using its airspace over pending dues, sources said on Thursday, forcing the airline to reroute some services and take longer flight paths.

According to sources, the restriction was imposed due to non-payment of outstanding charges, though specific details about the nature of the dues were not immediately available. An email sent to the Civil Aviation Authority of Bangladesh (CAAB) seeking comment did not receive an immediate response.

With access to Bangladeshi airspace suspended, SpiceJet flights from Kolkata to destinations such as Guwahati and Imphal are operating on longer routes. Flight tracking data from Flightradar24 on Thursday showed these services avoiding Bangladeshi airspace.

The airline maintained that its flight operations remain unaffected and that scheduled services are continuing in accordance with regulatory requirements.
