WJNWJN,
Welcome to FT.
A key to getting an upgrade is attitude. Be polite, friendly and humble. It never hurts, especially with someone who deals with agitated travelers all day, CS people like the change.
As you saw, most people try to be helpful. I'm sure the poster above got cut off on the way to work or a dog peed on his leg, thus partially explaining the posting above.
At least I hope so.
