First time on this site 🙂 We are on the east coast where the wait for my husband (type O, age 53) is about 6-8 years. We're considering listing at centers with significantly shorter lists, some of which are quite far from us. Our insurance has a sizeable travel stipend, so fortunately we don't think money for travel will be too much of a problem. We're mostly concerned about the amount of time it takes from getting "that call" to laying on the operating table when getting on a plane is involved. What is a safe distance to consider? Would the Mayo clinic in Arizona be too far for traveling from the DC area?
