The purpose of this study is to examine operational delay with on time performance at PT Garuda Indonesia located in Terminal 3. The problem of this study is there are delay due to flight operations and airport facilities. The study collected the data from the company and by doing the field research. Simple and multiple regression analysis, correlation coefficients, determinant coefficients and hypothesis testing were used to analyse the data. The results show that there is a negative and strong relationship due to Flight Operation with On Time Performance. The coefficient of determination is 92%, the results of hypothesis test (t-test) have a significant positive effect. The connection of delay due to Airport Facilities with On Time Performance is Y = 92,549 + (-0,123X) from the regression equation looks down (negative). The correlation coefficient r = 0.602 has a positive and strong relation. The coefficient of determination is 36.2%, the results of hypothesis testing (ttest) have a significant relationship. The connection of delay due to Flight Operation and Airport Facilities to On Time Performance is Y = 98,274 + (-1,772 X₁ ) + (-0,011 X₂ ). The correlation coefficient r = 0.960 means a positive and very strong relationship. The coefficient of determination is equal to 92.2%. Hypothesis test results (f test) have proven a positive and strong relationship.
