"AAA (alt 2) Hyatt code (15985) is another secondary AAA membership discount code at Hyatt. AAA rates are publicly advertised and require only showing an AAA membership card. FlyerTalk documents: another reported being asked only twice in 70-80 stays. AAA rates are typically 5-15% off, reducing hotels' incentive to verify. The secondary code designation suggests it may be for specific Hyatt properties or booking channels with even lower enforcement than the primary code."

"Pepsi 20937 is confirmed in Hyatt code directories. FlyerTalk user Colin stated: "US & MX hotels never check, in my experience" for consumer/FMCG brand codes. Pepsi is headquartered in Purchase NY with heavy Hyatt usage at mid-tier domestic properties (Hyatt Place, Hyatt House) — the exact brands identified as having the rarest verification rates. Consumer packaged-goods brands present the same ambiguous franchise/bottler affiliation challenge as McDonald's, making challenges impractical."

"Hyatt Senior Citizen rate (17497) is a leisure discount, not a corporate code. FlyerTalk confirms: "World of Hyatt Senior Discount — no company ID required, just age verification at some properties. Front desk may ask for ID to confirm age." This is a publicly advertised promotional rate, not an employee benefit code. Age can be verified by any government ID. Risk of rate-challenge at check-in is essentially zero."
