| The purpose of this quantitative study was to test for differences and changes longitudinally over time in the flight timeliness, leverage, and fuel costs of airlines operating in the United States. The main issues were ineffective operational efficiency, leadership practices, unqualified staff, and policies and procedures pertinent to operational management training in the airlines industry. The study included several forms of statistical analysis, namely, repeated measures analysis of variance (ANOVA) tests, paired t tests, Greenhouse-Geiser correction, and Greenhouse-Geiser adjustment. Results of the paired t tests, Greenhouse-Geiser correction, and Greenhouse-Geiser adjustment analysis showed clear differences in the flight timeliness, leverage, and fuel costs over time. Delays in flight arrivals and departures and high maintenance and fuel costs compromise operational efficiency and affect airline profitability and success. The study may contribute toward enabling airlines to improve operational efficiency and staffing policies, increase timeliness, and reduce costs. |
