The pay rates are current, they'll go up a dollar or so in OCT. You'll get 1600 a month for the first 4 months or until you finish OE, whichever come first. Then the 50x75 comes into play. But there is also a rig and you'll break 50 hours after 10 days on the road.
There is no telling how much flying you'll do. Most months I get an extra 10-15 hours above the 62 from the rig. I was supposed to DH to work today. Scheduling called this morning and my whole trip evaporated and now I'm on home reserve. If something doesn't happen in a few days it'll be guarantee this month.
