There is also a 1yr minimum in the delta before you go on the Caravan.
Only way you will get direct entry onto the van is if you have either significant experience on the caravan already, or have been flying in the delta with another company.
On a different subject, found out something interesting with the Airlink flights to Maun.
They have been told that the only way they will be allowed to fly there is if their flights are more expensive than Air Botswana.
Does Air Bots really think that price is everything to do with flying? A lot of these clients are flying in from around the world to stay in super expensive camps. They will fork out more for better service both in the air and on the ground.
All they need to do is be reliable and on time, and they will start taking business away from Air Bots.
