Wendy Wu Tours is offering free business class upgrades on fully-escorted China and Japan tours booked before January 20.

The Asia specialist says the move offers savings of up to £1,000 per person.

Upgrades are with Air China and business class includes a fully-flat bed with pillows and duvet; dedicated check-in and priority boarding; access to VIP business lounges plus upgraded food and wines.

John Warr, global sales director at Wendy Wu Tours, said: “The business class upgrade with Air China is one of the most luxurious additions to your holiday and highly recommended especially when you are flying 11 hours to the other side of the world.

“The inflight service is world class, so much so that you don’t actually want the flight to end. Combining this with one of our award-winning tours to China and Japan and all in all you have the ultimate Asia travel experience.”

The operator is also offering £200 per person off its group tour holidays to all destinations when booked before January 20 and says availability is “extremely limited.”
