I bought two PE tickets on Cathay bkk-hkg-lax through Amex Prem travel back in August. The return was for 9/19. I changed them on Aug 30 to depart BKK on 9/16 instead and was charged $100 each by Cathay and $39 each from Amex. On the 15th I was told by Cathay they cancelled my flights, eventually I was rebooked on 17th and missed meeting in LA I rebooked for. Now through Amex cathay says they will not refund the change fee "because they did eventually get me home' and "it was weather related change." Amex has not decided yet on their end.

What do you think about this and can anyone comment or give me advice. Thank you in advance
