Does anyone have experience using the new travel credit benefit with Membership Rewards? Called Amex but CSR not especially knowledgable and the wording on the info sheet not that clear.

Questions:
1. Iif I book directly with the airline (rather than Amex travel service), do I still get the credit? Perhaps after the fact?

2. Is there a travel agent fee for using the travel service as there would be with a regular travel agent? I used to use Amex travel when they had a bricks and mortar place. They began charging $50 to issue a tx and closed the storefront. Easier to deal direct with the airline.

3. Does the supplementary cardmember also get the travel credit also or just one per “account”?

4. Does each card on an account get the Nexus renewal credit?

Any hints/tips/ideas re them new benefits would be most appreciated.
