Flight Plan
According to the Colombian Air Safety Secretary, Coronel Freddy Bonilla, Lamia's flight did not followed the Flight Plan. Lamia's flight should have stopped at Pando Airport, located in Cobija, Bolivia. The flight from Santa Cruz de La Sierra to Cobija would have taken 1.5 hours. Estimated time on ground in Pando was around 40 minutes (possibly for refuel), but this stop did not happen. Entering Colombian air space the pilot informed Control he was proceeding direct to Medellin.
It is known that Pando Airport does not operate at night and the takeoff from Santa Cruz de La Sierra was delayed, so this is the reason Lamia's flight did not land there for refueling.
The question is: why they did not land at Bogota International Airport and refueled there?
