Just as I left Safari Air, they had implemented a thing that only allowed one flight into the delta per person. Had to sign a whole bunch of liability forms etc.
And I think they were only offering them to people that they had an interest in hiring.
Not sure if that is still the case now that the Ops Manager has moved on... but yeah. Safari Air even at the best of times didn't offer tons of flights... it was usually up to the pilots flying the plane.
Don't hit them up every day... It gets a little much. Making friends with the pilots is a better idea, they will know their schedule and who is on it the afternoon before.
