Thanks for your help about CX Asian F destinations. I'm now weighing up whether to buy an RTW in F or buy Europe - HKG round-trip then the Asian add-ons. I'm starting in Nice so really not bothered where I start the long-haul. Thanks for the tip about CX ex-FRA, but CX doesn't seem to have anything to match BA's current offer for LIS-HKG in F which is less than €3000 ! Are the CX F fares ex-FRA the best I can get in Europe ?
