Wow! Never book flight with American Express. Flight arrival got changed by the airlines so I needed to make a change of flights. Called multiple times only to be transferred from one person to the the next all asking for the same information. When I finally got someone who seemed to know what they where doing after explaining what I needed and giving them all the same info that I just gave to the previous representative they ask for your phone number in case the call drops put you on hold then disconnect the line after about 10 minutes. Zero call back! Last time I will ever book a call with them. Two hours later and I'm still calling back trying to find a resolution.
