airline maintenance, outsourcing, airline profitability


This study investigates eight viable United States major passenger airlines' outsourced maintenance impact on profitability between 1995 and 2019 by using panel data analysis. The results demonstrate that the percentage of airline outsourced maintenance and inhouse maintenance labor pay have no statistically significant impact on profitability. The researchers call for the further research with a larger sample, and more time periods to explore airlines' outsourced maintenance impact on profitability.
