Dubai, Mexico and the Caribbean have been added for 2021 to capitalise on pent-up demand for what it described as "perennial UK market favourites".
Caribbean destinations include Barbados, Antigua, Saint Lucia and the Dominican Republic.
Classic said the decision to expand its offering followed feedback from the trade; new product is on sale now, with live availability and dynamic pricing – and the promise of more additions to follow in the weeks and months to come.
Alex Gavalda, Classic’s director of product and commercial, said: "We are seeing strong, pent-up demand for these perennial UK market favourites and are making them even more tempting to our trade partners by offering them with the competitive prices that agents associate with the Classic Package Holidays brand.
"Live availability and dynamic pricing give us the flexibility to continually evolve our product, and over the next few weeks we will be adding new properties and destinations without compromising on quality.
"We are offering a wider choice to our travel agent partners at a time when challenging market conditions could see a reduction in booking options for the trade."
Classic said that owing to current Covid travel restrictions and many destinations’ plans for phased restarts, it would take a cautious approach to launching the new destinations, with no departures fixed for any earlier than 1 May at this time.
Si Morris-Green, Classic’s director of agency sales and marketing, added: "Our travel agent partners asked us to extend our Classic Package Holidays proposition beyond short-haul destinations, and we’re delighted to have been able to respond with the introduction of these new destinations.
"We want to offer travel agents the ultimate freedom, flexibility and choice for their customers and are constantly reviewing our product and booking process via feedback from our trade partners.
"Classic Package Holidays allows agents to make bookings with instant confirmation at any time of day or night, backed by the financial and safety guarantees of our Classic commitment."
