I am in large aircraft charter which is a little diffrent. Basically the key is flexibility and the charters represent big bucks so the company is very willing to pay to cover the trips.Our trips go all over the world but we have a lot of domestic and island stuff too.At the beginning of the month we get a bid sheet and we can bid for our trips by senority and days off. The only thing that really sticks are the days off as they change the trip to suit the aircraft more that the crew. On some lines 50% of what you do is commercialing out to meet the airplane, prior to 911 it was a pleasure not it is a real pain. We get 10 days off a month, usually you work 10 to 15 days and the rest of the days are standby days at home.(great time to cut the lawn and catch up on honeydo's) We also can volunteer to fly on our days off which give us an extra 250.00 per day, you can also volunteer for overtime if it is avialiable. Our garentee is 70 hours per month no matter what you fly. Sometimes the hours are long and the FA's a real pain but you as the captain must make things happen on the road. They give you the keys, the girls, and guys that think their girls,the jet and a structure to help you get the job done. If you do a good job you look good, if you do a bad job the whole company knows about it. Such is life in a small charter company.
