756 is junior to 737 IAH. You will be tired all the time with the 14 hour 3 days (changing). More flexibility with 737. If I was EWR based and junior, I would bid 757 due to being a line holder quicker. If you commute most 737 trips start early and end late. I;ve been on the 737 for 7 years and I'm tired of tearing up my uniform from getting into and out of the cockpit. 756 IAH is welcome to FLL, LAX, MCO, EWR. They are getting some HNL/OGG trips through LAX, but that will most likely go away after the SLI. FWIW, the 737 IAH has a ton of flexibility. So America, Mexico, Cananda, etc. My best schedule was IAH 737. I'm LAX now so schedule sucks a$$
