Risk Type Climate-Related Risk Definition Potential Financial Impact Short Term Medium Term Long Term Mitigation Strategy Physical Risks Chronic The risk of longer-term changes in weather patterns Sea-level rise in Miami, Los Angeles, Philadelphia and New York may require hardening of the airports in these locations, or even relocation. Because high air temperatures reduce air density, chronically high temperatures at some of our hub airports may require restricting the availability of seats for sale in certain markets, the use of aircraft with higher engine thrust and potentially reduced schedules. Given the vulnerability of these key airports to flooding from sea-level rise, and the resulting impact to business continuity, we intend to investigate options to mitigate the impacts of sea-level rise, which may include fortifying the shoreline around those facilities and, as a last resort, considering options for relocation to areas further inland. The cost/benefit of available options may lead to adjustments to our network. We also plan to engage with policymakers and airport authorities to explore paths to greater resiliency. Over the next five years, we plan to incorporate the projected impacts of climate change into aircraft purchasing plans, routing and scheduling. We will also work with airframe and engine manufacturers to develop aircraft that meet the technical specifications required for operation at airports with sustained high temperatures.
