When would I get on an A300? Well, probably never, since I don't fly American very often and they are the only US carrier that uses them. And even if I did fly them a lot, they only have six of them.

Now, if I was to book a flight on American and they put me on and A300, would I care?

No more so than when I flew on 757s and 767s on United after the attacks. I even took United 185 from IAD to LAX, which is, as you know, one of the routes the terrorists hijacked and the number is just one different than one of the doomed planes.

In other words, I wouldn't sweat it.
