Mercury Holidays has introduced tour-only pricing and options across its programme of escorted private tours.
The independent tour operator said the move means that clients can now combine a Mercury Holidays private tour with their own flights, allowing them to use their own airline reward points.
They can also combine the tour with another trip to extend their time away.
Mercury said the development aims to offer travel agent partners and clients greater flexibility.
Highlights include the 17-day Grand Tour of North India – visiting Delhi, Varanasi, Jaipur, Amritsar and the Taj Mahal – which costs from £2,133.
The 15-day Wonders of China private tour includes a four-night cruise on the Yangtze River, the Chengdu Panda Breeding Centre, the Terracotta warriors and the Great Wall of China. It costs from £3,164.
A 16-day Grand Tour of Sri Lanka itinerary starts from £2,521.
