Hilton (NYSE:HLT) and American Express (NYSE:AXP) announced that the companies, in partnership with Hilton’s ownership community, will donate up to 1 million hotel room nights across the United States to frontline medical professionals leading the fight against COVID-19.

Hilton is initially working with 10 associations who collectively represent more than 1 million healthcare workers to provide access to the program, designed to support individuals who would otherwise have to spend their own money on accommodations.

American Express, Hilton’s long-standing strategic partner, is investing alongside Hilton in the donation of the hotel rooms, which will be provided at or below cost by Hilton’s network of independent owners and franchisees.

Rooms will be available across a variety of Hilton brands, including Hampton by Hilton, Hilton Garden Inn, DoubleTree by Hilton and others. Hotels will be staffed by Team Members who have received additional training on relevant health and safety measures to safeguard their own and their guests’ well-being. Hotel rooms and common areas will continue to be sanitized using industrial-grade cleaners and updated cleaning protocols. In some high-demand locations, room availability may be limited at times.

The following organizations will provide their networks with further details about booking rooms through this program, which is currently planned to cover stays from April 13 through May 31.
