I'm assuming you're talking about October on-time numbers since the full November stats for both airlines won't be out for a month.
WN system-wide: 86.6%
HP system-wide: 83.1%
WN @ PHX: 89.1%
HP @ PHX: 88.4%
Yes, HP's mishandled baggage reports were dramatically lower *and* lower than Southwest's. And America West's load factor was higher than Southwest's - and they were the only carrier to post a higher load factor. BUT America West's November traffic was down 17.9% year-over-year while Southwest's was only down 1.2%. And which carrier had fewer complaints? That would be Southwest. Oh, and which airline laid off some of its hard-working employees?
America West *is* doing better. But WN is still beating them in several ways.
