"The AET code for Aetna is listed among standard Marriott corporate codes. Most hotel PMS systems automatically flag reservations whose discount exceeds a specified threshold for manual ID verification. For healthcare sector codes like Aetna, full-service and luxury brands like Ritz-Carlton, JW Marriott, and St. Regis have dedicated Rate Integrity teams. Aetna's code is considered moderate risk — not in the high-profile consulting tier that triggers most scrutiny."

"I work as a consultant and frequently ask for and use my client's rates (at their insistence, since I will be billing them back). I have been asked for ID maybe one time in 15 since February, when it was announced in this forum that rates would be ID'ed."

"I have been asked to show some proof couple of times. I normally show my corp id but credit card with employers name on it has worked, too. As would probably just showing my laptop with employer e-mail account or whatever. My impression has been they are happy with just about anything that proves I'm working for the company whose rate I use and why wouldn't they."
