Indigo will run first international service to Singapore from Gannavaram Airport on October 25. A row between the state government and Civil Aviation officials over payment of salaries to Customs officials to be stationed at Gannavaram Airport has delayed in running international services. Indigo will run flight between Vijayawada and Singapore two times a week. Based on the response from passengers, the airliner will increase frequency. Passengers from Vijayawada are boarding international flights at Hyderabad as there are no international services.
