I am so disappointed with the way American Express Travel treat theirs clients.I am a Platinum member and I booked a Trip on Saturday. After I booked the trip, I received an email saying that I needed to call them because there was an issue on the three passengers last name which is so long. Since that I have been calling and chatting to them to try to solve the issue with our last names.On Monday, I spoke with an agent through the chat and she gave the flight confirmation number. I put the number on United Airlines app, I chose the seats for all passengers, but now I cannot see it anymore. I called them two times without success and then I chatted with agent Ryan who tried to help me but unfortunately he couldn’t. He told me so from what he could tell it was a limitation there at American Express that they cannot issue tickets with the number of letters in all of the names combined as it appears on our passports. For any convenience to me it would be advised that I speak with the airline directly to issue the tickets to avoid any problems of communicating the limitations with the airline and any exceptions they will provide American Express to help the tickets get issued from this agency.I used my rewards points to buy the tickets and I paid the difference on the card. They want me to book directly through the United but the price right now is so high. It is not my problem that their system cannot handle it with clients names.
