More of the same poor performance as we've been seeing for the past few months:

• Most delayed airline -- again below not just the mainline carriers, but below all the regionals as well.
• Highest cancellation rate of the mainline carriers.
• Highest rate of mishandled bags of the mainline carriers.
• Highest DOT complaint rate.
• This report included the quarterly DB rates for Q2, and again UA was highest IDB rate of the mainline carriers.

What's scary about this is the margin by which UA is doing poorly.

Not only is UA 10% below the average in on time at 69.9% (vs. 80.7% average), they're more than 10 points below the next lowest mainline carrier (AA at 80.3%).

Similarly, the IDB rate is not just worse than everybody else's, it's double the average (2.11 vs. 1.05), double the next mainline carrier (WN at 1.05), and close to triple the next network carrier (US at 0.76).

Same goes for complaint rate -- while the average is 1.87, UA comes in more than 3 times that at 6.86. The next worst carrier has just over 1/3 of UA's rate (US at 2.50).
