Free two-night stopovers or holiday extensions are being offered by Wendy Wu Tours for a limited period.
The deal, available on new bookings made by April 30, provides en-route stays in Hong Kong, Singapore, Dubai or Abu Dhabi with guided touring, worth up to £450 per person.
Alternatively, two extra nights from arrival or departure destinations can be added or a £200 discount applied.
The promotion, covering departures this year and in 2026, comes amid heightened demand for multi-destination trips.
Specialist touring to Asia has surged 70% year-on-year, with 2026 bookings already up 40%, according to the specialist operator.
Solo travellers can also benefit, with free or reduced-cost options on selected dates.
The company is waiving supplements for customers who book in March or April to fly from Edinburgh or Glasgow on Emirates new Airbus A350.
Head of trade sales Gary King said: “Travellers want more from their holidays than ever before and this offer gives them a completely new way to experience the world.
“A free stopover means they can immerse themselves in an extra destination without spending a penny more.
“For agents, this is the perfect hook to attract new bookings and add unbeatable value.”
