It’s Halloween. BOO!

For at least two airlines — that means it is time to get scary.

Especially for some of the airlines’ top executives.

Friday over on Denton Drive here in Dallas, it appears that Southwest Airlines‘ former Chairman and CEO Herb Kelleher decided to go with the Willie Nelson/Biker combo look, while current Chairman, President and CEO Gary Kelly pranced down the Yellow Brick Road as Dorothy.

I don’t know what it is with Gary and his cross-dressing tendencies, but ever since he turned out as Edna Turnblad a couple of years ago — we’re almost afraid to look. (Last year Gary and two associates were attired as ZZ Top.) Early betting this year had Gary dressing as Julia Child.

But here’s the one that got me. Anyone know who that is?

That’s US Airways’ COO Robert Isom. I tell you what — that boy has the Barry Gibb thing going, doesn’t he? I hear he hit some pretty high notes Friday as well — as the US Airways’ executive team, aka the Bee Gees, entertained airline employees at the airline’s headquarters in Tempe.

Gotta love that hair.
