KTA has been briefed to grow UKinbound’s profile in the travel and tourism sector.
The agency’s managing director Gail Palmer said: "UKinbound provides a voice for tourism on behalf of more than 300 members and we look forward to making that voice heard within the media sphere and community."
Deirdre Wells, chief executive of UKinbound, said: "KTA PR is recognised for its 26 years of experience in the travel industry and it was essential that we chose an agency that can hit the ground running as our press office with key contacts in the travel, consumer and trade media. We are excited to be working closely with KTA PR as we move forward with new messaging from UKinbound and a fresh approach to media engagement."
