ACA has them on the Delta side and used to have them on the UEX side. We are being told that IA will not have them. The Delta side stand-up's are built well. They range 11-14 off per month with 80-95 hours block. Most of the standups give 8+ hours on the ground. I been doing them for 2 yrs straight a love em. But that will change once the Delta flying ceases in Nov.
