Rather than start a new thread I thought I may as well piggy back on this one.

What is the state of AM's short haul business class these days? I'm looking at GUA-MEX-SJD and once I've added a checked bag and seat assignments the upgrade comes out at about £75 or $100.

Is this likely to be a US First style seat or the wee pretendy business class we get in Europe?

Also are the lounges any better that the Priority Pass options?
