I've been reading the explorer ticket FAQs today (all day) and using the extremely useful Mileage Monkey tool - it really is great, but I clearly am a newbie!!

I plan to start in London with the following itinerary for my wife and I on two AONE6 tickets and have a couple of questions - see extract below:

I am going to YVR so I can take a paid return to Anchorage without losing out elsewhere.

Have I maxed out the opportunity / number of first sectors or am I missing some elemental tips?

Secondly, I am emigrating to Australia later this year (soon after the RTW) and whilst I need to come back to the UK, I wonder if I should post the trip through my BA (62271 miles and 2760TPs) or Qantas card (3060 SCs)? Any views?

Thanks All,

Marcus.
