Yes Air Link has to be equal or greater in price than Air Bots but I doubt that is going to make any difference in keeping Air bots competitive once Air Link arrive.
However over the last month Air Botswana have arrived on time and with all the guests bags, so perhaps they are starting to shake things up now that Air Link will be sharing the route. But I doubt it.
To the poster who was thinking of arriving for a week in June I doubt that will do you much good, peak season would have begun and most companies need to train the pilots they have already hired. I would suggest you save a little cash and come later in the year (Oct-Nov) and plan on staying for 6 weeks minimum.
