delivered at all costs? >> we always factor cost into the decision-making but on the same note we're going to service the customers. and if we have to fly multiple flanz to get package moved so those packages get delivered for that christmas event, that's what we're going to do. >> so it sounds like from what you described i should never get a package late. >> that's totally not true because there are certain situations that are even beyond ups's control. weather plays i would say a 30% to 40% role. >> as far as the northeast is concerned, the snow intensities have all been reported as light. >> reporter: to mitigate the risks of weather, ups has an internal meteorology team that forecasts potential problem areas. >> we need to let the decision makers know when are these storms actually going to impact the airport? because that allows them to rearrange the landing schedule. >> are you guys ever wrong? >> oh, yes. occasionally we're wrong and we hear about it. that's one thing, we get feedback right away from our customers.
