The data included 437k customer email addresses (a further 868k generated email addresses from the booking.com and Expedia platforms were not loaded into HIBP), names, physical addresses, phone numbers, booking information related to travel plans, purchases recorded by the platform and in a small number of cases, partial credit card data. The data was provided to HIBP by a source who requested it be attributed to "ayame@xmpp.jp".
