Andriyko & A_T_G_C tell the airline/Amex travel/TA that change of policy doesn't supersede the conditions of carriage on the date the ticket was issued as it a legal binding contract to which both the airline & pax agreed. The new policy has not been agreed to mutually, hence the agreed policy is still in place. In addition to that I would also tell them that I shall consider my legal options. Under the conditions of carriage article 11.3 (this is applicable for itineraries that have been completely & partially canceled).
