When flying from Jakarta to Vermont, 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 Jakarta Soekarno-Hatta Intl Airport (CGK) and Burlington Airport (BTV). Codes like Burlington Airport are often used to just call airports uniquely. Rutland Airport (RUT), Morristown Morrisville-Stowe Airport (MVL) are some additional IATA codes for airports related to your trip.
