To be honest, and I don't mean anything personal here, but to ask for a J-class ticket for two will cost them a heap of money. They could do like a lot of other airlines do and not offer you a thing, but you should be glad that they've offered you an upgrade for two sectors.

It SOUNDS like you are milking something here though in actual fact you are probably not and were rightfully angry at being treated most unhelpfully. Have you rejected the upgrade? Because personally I think that's the most you'll get out of them.

Considering the fact that this happens relatively frequently (with overbooking of Y and upgrading to C) in BKK (with c@*p agents), then if they offered J tickets all the time, they WOULD go bankrupt.

Nasty experience. And I think the TG bozo did it deliberately, so he'd give TG CX's money from your ticket. Though of course...who in their right mind would fly TG's First when SQ is available...
