As a rip off will anyway happen, then it's better to at least make sure the handling itself will be arranged on a good level. So we have Streamline and EuroJet...both will charge shed loads.
Streamline will be using their local contacts, and most probably will arrange handling via some 3rd local handler.
EuroJet should have their local people, as they have a local country manager based there....
Anyway, for hotac - hotel Tajikistan, is crew's favorite. You'll have wifi, and normal food for breakfast...kind of.
To escape any stupid charges, always make sure that when you are on the ground, locals know exactly what they need to do, and what exactly you need from them...otherwise they will charge extras for what they think you would need, but you actually never requested. Goood luck!
