"Pfizer holds two Marriott codes (4899 and PFZ, with PFE as a third variant). This code duplication reflects Pfizer's large managed travel program. FlyerTalk notes: "In the US and Canada, never asked to show a work badge. Overseas — they tend to follow the rule by the book." Pfizer's dual-code structure suggests a formally managed travel program that may share usage data with Pfizer's travel desk. Risk is medium — consistent with other pharma codes at full-service Marriott properties globally."

"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."

"I think the generic 'show corp id' designation means show the company business card. I think a lot of us don't have them or, if we do & we're not going to an office that we'd need to show them, leave them at home. I worked for some F500s that didn't require corp ids with shiny smiling faces on them & others that did; same with company credit cards. All, however, provided biz cards when working for them."
