So far today, United has had their best operational day in a week with only 440 cancellations.

Meanwhile, here are the cancellations for the rest of the US:

United, 440
Southwest, 22
JetBlue, 22
Delta, 6
American, 0

United has pretty much cancelled more flights today than just about every other airline in the world combined. And today is the best day in a week.

Everyone knows that United is trying to the the biggest airline, but it is obvious it is far from achieving this goal.
