Thomson and First Choice have added Montenegro for summer 2018.
The programme features Ulcinj, Budva, Becici and Petrovac with flights from London Gatwick, Manchester and Birmingham.
The TUI-owned operators said they had introduced the destination following a rise in demand for mid-haul holidays.
Meanwhile, Thomson has added new long-haul city breaks for late summer/early autumn 2017.
More accommodation has been added in New York and Las Vegas, while Boston, San Francisco, Los Angeles and Dubai will be new from the autumn.
Guests can stay at The Boxer Boston in downtown Boston, The Grafton in West Hollywood, the W in San Francisco and The Palm in Dubai.
Guide price for a four-night stay in New York flying with Norwegian Airlines and staying at the 3T Amsterdam Court Hotel near the Rockerfeller Centre is £789 per person (November 25-29).
