"GE's IHG code is directly mentioned in FlyerTalk: "The GE code brings a Holiday Inn rate down from $114 to $84." A more recent thread warns: "In the past two years, IHG has been very careful in checking on people using IBM and GE corporate rates. Not only corporate ID is required, also an email from IBM or GE to confirm staff identity in extreme cases." GE's documented 70% discount at InterContinental Chicago makes it a high-audit-trigger code at luxury IHG properties. Holiday Inn Express tier: low risk. InterContinental/Kimpton tier: high risk, consistent with the brand-tier pattern across all IHG properties."

"UPS' IHG code (108146) is for one of the world's largest package delivery companies. UPS has 500,000+ global employees and major hub in Louisville KY. IHG enforcement: Holiday Inn Express near UPS distribution centers (Louisville, Atlanta, Dallas, Newark) rarely checks; IHG InterContinental/Kimpton properties in business centers are more likely to verify. UPS employee IDs are physical company-issued photo badges recognizable to hotel staff. No specific UPS IHG denial incident documented in FlyerTalk."

"I believe it's a legitimate discount code because I have permission from FedEx to use it. At the end of the day, that's their call, not yours."
