"DLA (Delta Air Lines) is listed at hotelcorporatecodes.com with verification "⚠️ Sometimes" and 10-15% discount, North America scope. No dedicated FlyerTalk thread on Delta/DLA ID enforcement was found. General pattern for airline employee codes at Marriott: medium risk, primarily because airline employee IDs are easy to request (physical company badge) and airline employees are frequent Marriott guests, making front desk staff more practiced at requesting verification. Properties near major Delta hubs (ATL, JFK, LAX, MSP, DTW) have higher awareness. Select-service and suburban properties: rarely checked. Full-service urban flagship properties: occasional."

"I used to work night audit at a 4 diamond Marriott resort. It was me, an 80 year old valet who just slept in the cars, and a 4'11" security guard. She wouldn't check anything out because "I'm a woman. If there's someone there, they could attack me." So I, the 19 year old woman, would investigate. Guest needed towels? I brought them. I would have to go up to a computer room to run some of my reports. I occasionally had to pee, because I'm selfish like that. So whenever I was gone from the front desk, it was just unstaffed. It sucked."

"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."
