I worked there a few years ago, I think E110 base was $25K + .02 a mile and $1.25/hr per diem. Flying into or starting on a day off was $140 extra per day. It usually worked out to $500 a week after taxes, but I also flew my @$$ off. I was based in LCK, as E110 CA and did only on demand freight charters. It's a tough life, often flying all night with little or no sleep. But in the end it was a good and rewarding experience.
I also flew the C208 for them the base was $18K + per diem, miles etc. worked out to $350/week after txes.
And as E110 FO it was $14K base + per diem, etc worked out to be $250 a week after taxes.
If I remember correctly the POH required 2 pilots to operate the E110. AirNow owns an STC with provisions to operate it single pilot. Non of the E110s has autopilot. Some also weigh in at 13,000 lbs. requiring a type rating.
Looking back at the ops that company used to conduct, I flew it many times single pilot on UPS "Scheduled" runs out of DDH, ALB, BDL, BUF, ELM, etc. No problem, you have planned for that. I mean you are on a schedule and you get to sleep. But on the "on-demand" side you can be paged anytime 24 hours a day. Imagine just laying down to bed at 11:00 PM and your pager goes off. You jump out of bed and in :45 mins you have to be airbourne, single pilot, and on your way to pick up auto parts in Yippsilanti MI, in icing, IMC, snow etc. and fly them to Laredo, TX. Talk about a long night flying with no sleep. That's why they always had an SIC on the "on Demand" runs. I guess they figured by cutting a little safety out of the loop, they could save a few dollars. Good luck to all.
