Wendy Wu Tours is offering VIP Business Class upgrades with Cathay Pacific from £299 per person on escorted China, Japan and Vietnam tours booked before the end of the month.

Those who take the upgrade by November 30 can sleep on a fully-flat bed and have access to the lounge at the airport.

John Warr, global sales director, said: “The business class upgrade with Cathay Pacific is undoubtedly one of the most luxurious business class services in the world having won numerous awards and commendations over the last few years.

“Combining this with one of our award-winning tours to China, Japan and Vietnam and you have the ultimate VIP Asia travel experience.”

Upgrades are available on both outbound and return journeys from £1,299 per person, but the operator warned agents that availability is “extremely limited”.
