MAF flights

Is it possible to book MAF flights from the USA? I have tried going online to their website and can't find any schedules of their flights there, let alone a way to book a flight. I have tried emailing them at the email address listed on the website and got no answer. I will be in Mt hagen and I want to go from Mt Hagen to Tari and return which I understand that they do. Otherwise the only other option is to go back to Port Moresby and fly a round trip Pt Moresby-Tari with Air Niugini which I prefer not to do, as I would like to stay away from Pt Moresby if possible. Also anyone know of a cheap place to stay in Tari? Thanks in advance. Susan

almost impossible to book from outside png...there are flights,but are hard to get on due to maf being a cargo carrier,and the planes are very small,with passenger seats limited,most are always booked out ahead,you do have the option of mt hagen to mendi and then onto tari by pmv(road)and return?take a small amount of luggage if you do the bus route as space is very tight/the mendi to tari leg is slow due to bad roads.see previous posts on tari accom!don't get confused by the conflicting posts by travellers!!!!
