United Airlines suddenly getting real competitive in one key performance metric

It's only the first week of one month. But United Airlines might have something to be very happy about when July does end 3 weeks for now. That is, if the carrier keeps up the on-time arrival performance it has demonstrated for the first 7 days of July, typically one of the busiest travel months of the year. According to data from masFlight, United ended the first week of July with the best overall on-time performance of any of the 4 major domestic carriers. The numbers show United finished the week with 81.7% of its flights arriving on time. The UA results for the first week of July put the carrier well ahead of perennial on-time frontrunner Delta Air Lines, which slipped in the past week with only 77.4% of flights arriving on time. <br/>
