The OTA on Wednesday (24 September) said it had taken a strategic decision "to commence an orderly wind down" of its B2B segment.
Classic will take no further bookings, but will continue to support agents with any existing bookings. A total of 26 Classic Collection colleagues will now enter into collective consultation with the group.
On the Beach confirmed the decision in a pre-close full-year trading update.
"Over the last 18 months, we've made significant improvements to our B2B technology and proposition," said On the Beach Group chief executive Shaun Morton.
