I apologise if I may have sounded a bit off...

And yes, I did just wake up, thanks ! I'm in asia right now.

What I meant was that it is improper for you to dispute the charges to amex. You have already used your ticket.. and that is something to be said. If you dispute it.. well, you might be starting something you do not want to.

Basically - please do just write in, call CX and see what you're entitled to. Yes you were to be seated in J but was upgraded to F and you feel that you did not get treated the way you were expecting to.

But really, is it just because that asian carriers try to kow tow to their western clients that you feel justification that you could have received more after having received your upgrade?.. ok on a non working seat..

But did you even attempt to ask if you could change seat inflight .. did you tell the ISM that? Did you even communicate that you were not happy...

If they gave you only $50 voucher, that says to the CS department that it is a minor issue as far as the ISM is concerned...

But anyway... no matter how we feel is already justifiable or not, you will still write into CX Customer Relations. So just let us know what they say to you in return..
