I can understand how it might seem that way. And taking major capacity offline isn't good in any business, but as you (@chipmaster) point out, it has to be done occasionally. What I *can* assure you is that as nasty as this runway closure seems, it is HIGHLY planned for, along with a number of contingencies, and all the stakeholders (airlines, etc.) are involved in the planning. FAA/ATC will have traffic management programs in place to avoid chaos on that (arrival) front, but if the individual airlines don't adjust their capacity/schedules to match the airport's, then it's on them. The difference between this and a significant weather event is that they have been talking about this for months, working with the users to be sure that everyone understands the capacity reductions, and then, the airlines who are paying attention will adjust their schedules -including allowing for connecting pax- well in advance. It doesn't mean that ALL flights will be delayed, or everyone will feel the pain, and I think there is usually plenty of leadership working on this - it's not their first rodeo.
