Another vote for NufNuf who has just rejigged my RTW ticket. The DONE4 is now rerouted OSL-LHR-HND-SIN-NRT-MEL-CHC//NAN-LAX-BOS-ORD-LAX-LIR-LAX-LHR-DOH-OSL.
With codeshare booking, this should earn 20,038 with TPs to BA. I've got a couple of other bookings prior to and during this ticket that will add another 660 TPs so well in the bracket for BAC Gold at the end of this trip.
He worked hard not only on the routing but for sensible transfer times at airports (minimise chance of lost bags whilst avoiding 8+ hours at LAX etc). The bold indicates stopovers with a minimum of 3 days. Since I live in the UK, the DOH trip is actually 3 months after we get back from the main RTW journey so it's almost like a free bit of late autumn warmth.
I've already been warned about JL setting cabin temps at 26C/80F so travelling in shorts/t shirt on those sectors!
