I've just booked an AONE4 ex MRU for $8200 including taxes and charges. MRU-LHR-NCE-LHR-DOH-LHR-YVR-JFK-SYD-AKL-SYD-HKG-NRT-SIN-HKG-JNB-MRU. 16 flights in total of which only the LHR-NCE-LHR and JNB-MRU are in Business Class, ie. 13 are in First Class. MRU-LHR, LHR-BAH-LHR-YVR, JNB-MRU with BA, YVR-JFK, SYD-HKG, HKG-NRT, HKG-JNB with CX, JFK-SYD with QF, SYD-AKL-SYD with LA. An average of $500 a flight.

MRU not easy to get to, but am ending a previous AONE in CAI, so am spending $1100 for a CAI-DXB-MRU in EK F - which also gets me 2 nights comped at the DXB Ritz-Carlton incl. transfers, useful given the 0025 arrival in DXB and the 0255 departure from DXB.

I will report on the trip later - I'm looking forward to comparing 5 airlines' F product.
