I love taking Amtrak to and from NYC, I'd never change it!
I've even commuted that way from Seattle to LA once, stopping by SF.
As it was said on here before:
Is up to us to make our own choices when it comes to getting a plane ticket on United, Delta, etc, and what kind of seat/service do we want?
Flying is tough? Some folks can't afford flying and take greyhound across America, that's tough.
