"GE (alt) Marriott code 9360 is a secondary General Electric Marriott code. GE's primary Marriott code pattern is Medium risk — FlyerTalk documented GE as one of the companies that monitors internal employee use of hotel corporate codes, with documented terminations for leisure misuse. Marriott properties in GE-heavy markets (Cincinnati, Boston, NYC) are familiar with GE employee IDs. No specific 9360 denial incident found; risk pattern mirrors the primary GE code."

"My last couple of corporate RFID cards had no company name on them for security purposes. My current company doesn’t do business cards. I use my Bonvoy card for corporate travel to get the points. I’d have to write them an email standing at the check in desk, I guess."

"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."
