IHG Rewards Club has on-going 20% to 35% off rate promotion (the baseline discount appears to be 25%) for airline staff that is valid for non-crew members too.
The airline staff rate is valid at participating InterContinental, Crowne Plaza, Indigo, Holiday Inn, Holiday Inn Express, Staybridge Suites, Candlewood Suites, Even and Hualuxe hotels.
You can access this offer on IHG’s website here.
Note that the terms state that you must have a valid airline ID and fill out a PDF that can be found from the age (likely not enforced). This rate can be booked maximum of 30 days before arrival and for 7 nights at a time.
