IndiGo Airlines is introducing these direct flights as part of the UDAN (Ude Desh Ka Aam Nagrik) scheme, focusing on promoting regional air connectivity across India. The winter schedule will see the launch of flights connecting Surat and Diu, with a layover in Ahmedabad. These flights are expected to operate on all days of the week except for Wednesdays, owing to the temporary runway closure at Ahmedabad airport. The flight duration between Surat and Diu is estimated to be approximately 45 minutes.
