Air Seychelles is selling flights from London Heathrow and Manchester to Hong Kong via Abu Dhabi for £307 & up – round trip incl. taxes.
The flights from London or Manchester to Abu Dhabi are operated by the 4-Star Airline Etihad Airways, from Abu Dhabi you continue with Air Seychelles to Hong Kong. The fare is valid for travel commencing between 24 March 2013 and 10th December 2013. You have to book by 18 February 2013.
I’d only recommend this fare, if you want to spend 1 day in Abu Dhabi, because you’ll have a 14 – 21 hour stopover on the outbound flight.
