I needed to change my return flight from a trip to Europe. Aside from the fact that they have a very high change fee, which is to be expected (I guess) for tickets purchased with reward points, expect exceedingly long hold times, representatives that are poorly trained and have to put you back on hold several times, a very high instance of "dropped" calls, and ultimately not having your problem addressed. For this one change I spent a total of more than 12hours on the phone and ultimately had to buy another ticket from another airline and lose the return flight I booked with Amex. They are taking no responsibility for this wretched treatment. I'm closing my Amex Platinum account and going to Chase.
