Regardless of the time of day you decide to fly, the ticket price will remain around the same. Book flights from Boracay to Hanoi as you normally would.
Boracay Godofredo P. Ramos Airport is MPH and Hanoi Noibai Airport is HAN. These codes are created by the International Air Transport Association (IATA) and airlines use them to identify the departing and arrival airports in the flight routes they service.
