"Pfizer holds two Marriott corporate codes (4899 and PFZ), reflecting the company's size and travel volume. FlyerTalk's Marriott ID thread notes: "In the US and Canada, never asked to show a work badge. Overseas — they tend to follow the rule by the book." One key risk factor: Pfizer's dual-code structure suggests a formally managed travel program. Corporate contracts sometimes include provision for hotels to share guest lists with the company — unauthorized users could be flagged to Pfizer's travel desk."

"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 wanted a higher room floor at a Seattle area hotel. I requested it at the front desk when checking in. The front desk thanked me for being a platinum member and told me that the hotel is fully booked and no “upgrades” to a higher floor for me. The girl behind me checked in and she was thanked for being gold, and they gave her a free upgrade to a suite and let her choose which room she wanted! I asked about the upgrade and they told me it’s random. I spoke to the manager and the manager said lots of rooms available and she gave me 5 rooms to choose from. 🤷🏻‍♂️ In the end, I got my upgrade. Had to fight for it."
