Actual operational and financial results of SkyWest, SkyWest Airlines and ExpressJet will likely also vary, and may vary materially, from those anticipated, estimated, projected or expected for a number of other reasons, including, in addition to those identified above: the challenges and costs of integrating operations and realizing anticipated synergies and other benefits from the acquisition of ExpressJet; the challenges of competing successfully in a highly competitive and rapidly changing industry; developments associated with fluctuations in the economy and the demand for air travel; the financial stability of SkyWest's major partners and any potential impact of their financial condition on the operations of SkyWest, SkyWest Airlines, or ExpressJet; fluctuations in flight schedules, which are determined by the major partners for whom SkyWest's operating airlines conduct flight operations; variations in market and economic conditions;
significant aircraft lease and debt commitments; residual aircraft values and related impairment charges; labor relations and costs; the impact of global instability; rapidly fluctuating fuel costs, and potential fuel shortages; the impact of weather - related or other natural disasters on air travel and airline costs; aircraft deliveries; the ability to attract and retain qualified pilots and other unanticipated factors.
