monthly guarantee at ACA is 75 hours. Our contract says lines will be built as close to 89 hours as possible. Most lines in IAD and ORD average in the high 80's while LGA lines havent come close to 89 hours in a long time (usually in the low 70's). CVG and BOS are somewhere in between. I made 32K my first year as an FO (includes per diem) at ACA while hardly picking up any open time. Your results may vary.
