As many on these forum I fell this is a big let down and devalues the card certainly to the level that I'd be not willing to another $900 annual fee.
I wrote them a complaint to express how I feel, don't expect much out of it, but please everybody speak up and let them know why we are leaving:
Dear Sir or Madam, I am writing to you to express my huge disappointment regarding the letter you recently sent me outlining the changes to insurance included with the Platinum Charge card. Essentially what this change come down to is that you have now set the Platinum Charge Card insurance on equal terms with insurances you get with other Platinum cards. This hugely devalues the Platinum Charge Card for me and in my opinion makes it a price of $900 not competitive in the market. I have for a while considered the Citibank Select card at $700 a year with equal benefits. The only major differentiator that made me not switch was the travel insurance with AMEX Platinum Charge Card which you have now changed. Given that and the much better acceptance of a VISA card versus AMEX and lesser surcharges you have just with this single move added to my decision to switch to Citibank Select VISA from AMEX. As I am about to go on a holiday which is still covered by the insurance I'll going to cancel my AMEX card in May after my return. Should you have anything to say for yourself, please do so before. Please do not send me a standard reply about all the other benefits as this will only strengthen my resolve to switch if i don't get the customised premium service you so much advertise.
