Apologies as I imagine this has been asked & answered elsewhere multiple times: I’m headed to Seattle for work in March. DL Amex reserve holder. Since I’m booking main cabin I was just going to use my company travel agent to book my flight. It’s still not a cheap flight and I really don’t care about MQD or whatever they’re calling it now as I’m lucky to reach Silver. Terms state you have to purchase flight with Amex to use CL. Is this something they are even able to verify when you check in? Is the info from your boarding pass that detailed?
