When getting to your destination is the No. 1 priority, which U.S. airline should you fly?
The data suggests you should go with Delta, which shown remarkably strong operational reliability over the past couple of years. Earlier this month, Delta estimated that it would cancel only 472 flights for maintenance reasons this year. Yes, that number does not include Delta Connection flights. But it's still strong, almost certainly far better than other U.S. airlines.
"Most of our competitors hope that that's their number for a month," Delta CEO Richard Anderson told investment analysts earlier this month.
By other metrics, Delta is also ahead of the competition. But I should point out that in the charts below, Delta has perhaps not given the public a full picture of the competition. Three airlines missing from this list -- Virgin America, Hawaiian Airlines and Alaska Airlines -- also run strong operations. But they are much smaller than Delta, so possibly it's not a fair comparison.
