"Southwest Airlines's Marriott code SW8 is an airline employee code. Airline employee IDs are physical company-issued badges — well-recognized by hotel staff at airport corridor Marriott properties. Properties near Southwest's Dallas Love Field HQ, Phoenix, Baltimore, Denver, and Las Vegas hubs are most likely to verify. FlyerTalk's general airline employee code thread: "Airline codes are more likely to be checked than random corporate codes because the front desk knows what an airline badge looks like." No SW8-specific denial documented."

"I have a close friend who is a GM at a Marriott property in a fairly large US city (top 25 metro population). Their opinion is basically, "Hey, it's business. I'm not turning away a paying guest if they don't have the right ID." In this person's younger days as a front desk agent, they enjoyed catching people trying to use a corporate rate that the guest was not entitled to. As they became higher up and saw the books, occupancy rates, etc... Corp ID's became far less important than filling rooms."

"We know what the various Deloitte, EY, PwC, Google, Meta, etc badges look like. If you work for the company, it’s not a problem to verify that you work there. We do this for the random people that say they work for Deloitte, when in reality, they just refill the vending machine at a Deloitte office."
