Mate, stay far, far, far away - also if they offer their b747-400 PTF scheeme. They, i.e Mountain High, Airborne, AAI have a long trail behind them paved with people left in a more miserable state than you can imagine. Guys have been forced to sell their houses because they were xxxxed left, right and centre. These outfits donīt even reside at the bottom of the barrel - they live under it.
My best advise if you go own this trail is NOT to considder whatever "contract" they offer as an agreement or contract whatsoever.
Pm if you want info
