<Screams out loud>
OK, I've played this pitiful, insulting, painfully slow game three times with three different email accounts (I need to book something in the near future, so was motivated) and have not one registration email or discount code to show for it.
I'm convinced now that this is AA's very cynical test of what people are willing to endure to get something (anything!) from an airline. If you'll do this, you'll sit on the tarmac for hours, fly in a filthy plane, buy junk food, and put up with a broken seat. (Though an alternative explanation is that this is certain evidence that the talent in AA's marketing group have jumped ship.)
