Sabre Hospitality

The systems of Sabre Hospitality Solutions (Sabre), a service provider used by Trump Hotels, were the site of this event that suffered from a data breach.

On June 5, 2017, Sabre reported that a third party had gained access to account credentials, giving them access to payment card data and particular reservation details for certain of our hotel bookings made through Sabre's CRS.
