"The AMX code for American Express employees is widely circulated. Community members note that "neither Amex Platinum nor Amex Bonvoy cardholders have any special corporate codes — this is strictly for Amex employees." Hotel staff may require employee verification. No specific denial cases documented, but risk noted as moderate given Amex's large employee headcount makes staff less suspicious of claimants."

"I had to change my email to my personal email account. My IT sucks, I have had so many joe.smith1 to joe.smith9 at my corporate name dot Com. Why I like to get my folio in person and on my email. Miss a receipt and your expense report gets rejected. Only been asked once for corporate proff, but I am nice to the staff and explain what's going on before they get a chance to ask. IT still has not figured out how to link everything to Concur for hotels. And it's a huge company"

"I don't do mobile check-in if I'm wanting to upgrade. I check the app before I go in to see if any suites are available to book during the duration of my stay. If there is I just say "Would it be possible to get upgraded to an available suite with my platinum benefit?". Of course this is typically at the hotel that I stay in about once a month for 3 day at a time for work. The front desk pretty much knows me and know that I am fairly low maintenance."
