When flying from Bandung to Bishkek, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.
This is defined as Bandung Husein Sastranegara Airport (BDO) and Bishkek Manas Intl Airport (FRU). Codes like Bishkek Manas Intl Airport are often used to just call airports uniquely.
