He constantly tries to defend their policies and is against any federal regulation of them
You mean the same Patrick Smith who wrote jut last October:
Assuming the airlines will not police themselves into submission, we've reached a point where government involvement is perhaps the best option
Or how he was too easy on the airlines in the very article you reference when he said:
If you find it hard to imagine any plausible reason for locking people in a ground-bound plane for 10 hours, so do I, and frankly there isn't one. Such breakdowns are abhorrent and inexcusable.
If "abhorrent and inexcusable" is how he "constantly tried to defend their policies", I hope he never tries to defend me!
He wasn't defending the airlines in that article, he was explaining how such things could happen and how some of the proposed remedies could actually make things worse.
I do read his columns and I actually read them, I don't jsut skim them until he disagrees with me and then run off claiming he's a Running Dog Capitalist Lackey.
Do I expect him to be unbiased? Not really. He's writing an opinion column. However, his bias doesn't necessarily co-incide with the airlines and it frequently leads him to criticize them, sometimes harshly.
Sure his criticizing airlines might be dangerous for him, but to his credit, he does it.
