Actually, I've read through this entire document. Much of the data can be skewed in lots of direction considering *most* of the airports out there aren't considered mandatory reporting. In other words, the airlines do not have to self report if they don't want to.

With that being said, our connection carriers are having issues. They have chonic delayed flights and a hire percentage of the delayed flights. Also, they have significant baggage issues. Some of our connection carriers are losing bags almost twice as much as mainline. Mainline lost less bags than last year. Ironically, Southwest, who doesn't transfer bags between carriers or codeshares, lost more bag this January compared to last year and those numbers were hired than DAL. Additionally, you are three times as likely to get involuntarily denied boarding on Southwest as you are with Delta ... and more likely, it is the people who bought the teaser fares.

There's some good in there, and some bad. We gotta get our hands around our connection carriers. Our passengers deserve that.
