Passengers of SpiceJet flight SG447 faced major inconvenience on Saturday (July 19) after their scheduled flight from Darbhanga to Delhi was cancelled due to a mix of technical issues and operational limitations at Darbhanga Airport. Originally scheduled to depart at 11:40 am, the flight was first delayed due to technical problems with the aircraft. SpiceJet then arranged a replacement aircraft. However, Darbhanga Airport, which functions under defence control, imposes a strict sunset curfew on civilian flight operations.
