"GE (alt) Hilton code 0072799100 is a secondary GE code. The same enforcement pattern applies as the primary GE Hilton code: approximately 20% verification rate overall, higher in UK/European properties post-2022. FlyerTalk noted GE has company policy against using corporate rates for leisure travel and has disciplined employees for this violation. Secondary GE codes circulate less widely than the primary code, potentially reducing audit flag probability at some properties."

"I don't know what will happen if these hotels, car rental companies, or other providers start asking for corporate identification. It seems problematic. Hopefully it will be that only a few locations, of a few brands, are demanding identification and for a specific reason."
