Not sure what the current contract is, I worked for them both full time and part time, full time I was making a fixed salary plus benefits like: housing (wifi, all utilities paid plus a daily maid), car and fuel, cellphone and minutes, meals at work and free access to the activities of the tours (usually on a tour you spend the whole day out, fly to an island in the morning and you come back before dark). I don`t remeber if that inlcuded my fuel and cellphone allowance but I was making around 1400 USDs a month. As a part time pilot (not necessary part time schedule), no benefits and 50 USD/hour at a rate of 40-45 hours a month .
those benefits are massive, at my second job I was getting a salary and no added things, renting an house/apt is really expensive so is owning a car. For a studio I use to pay with utilities, 1000 USDs a month and I would just use public transportation to get around...would ride in a beat up cramped of locals hyundai van with my flying stuff, weekender bag and a 6'7 surfboard...fun times.
If you think how much you really work, the money is a lot, pretty much you show up at 0800 at the airport, it`s a 10 minutes drive from pretty much anywhere in town (never had crazy early day starts), taxi the plane to the terminal and get fuel, do the ck in and cash the money from the pax, fill up a load manifest, do some W&B and performance and at 0900 AM you are airborne, by 1030 AM you are already sitting at a resort waiting for the tourists to do their tour (or go along if you wish), at 0300 PM you fly back and by 0500 PM you are home. This is pretty much 90% of the flying, the rest are drop off charters and in some rare occasions you have 2-3 days long charters to the most remote Islands (that`s really the best part).
If you remove the benefits it`s like making 2500 a month, salary is pretty much this even on bigger twins or as FO on a DHC6/Y12.
