I am planning to fly to Manilla (probably on QF) to pick up a cheap business class airfare to Europe (probably on Qatar). As I understand, transit through passport control and re-check-in can take up to 4 hours. Does anyone know if you have carry on luggage only, weather you can transit in Manlla international airport and pick up a new flight, without having to go through passport control (i.e. stay airside between arriving and departing flights from different airlines)?Many thanks for any help that is available!
