I'll take a shot at these:
That sounds great! I've done 2 OWR in J and it took months. I imagine this will take even more but ostensibly worth it. Say you get back to Perth in May and decide to change a date for 2020 is it possible? I think it is, just seems like a long time between flights which makes me a little nervous.
Yes, but:
1) I think there's a 365 day limit between your first and last flight on an itinerary i.e. it can't span more than a year.
2) You can only book flights so many days out, which can make booking over such a long timeframe difficult. It either means paying a lot of change fees as you book it progressively over the course of a year, or, booking it without such a long horizon, which can mean availability issues. For example if you wanted your itinerary to end in September next year, the latest it can start is September this year, the availability for which will be low because it's only 3 months away.
3) You can change anything prior to departure (on the first flight) by paying a change fee but after you depart it is much more restrictive. I believe you can only change flight dates - for example, if you have a CX flight HKG to PER, you can shift the date (if there's availability) but not the carrier, or add a stopover to HKG-SIN-PER, etc.
I'm actually not sure what you mean. I take it NA is North America and as I only want to go to Western Europe are you saying it is not worth it? Or not workable? Is it the 3 continent rule?
I think What
@appaz getting at is that you will run up against mileage limits if you try otherwise. Going all the way to western europe (LHR) and east coast USA (NYC) (or Southern US such as Texas for that matter) adds on extra miles that get you close to the 35k limit. You might be better off saving the miles for premium travel on your longer legs and paying cash for a fare for example from LAX or SEA to your East Coast USA destinations.
Interestingly being based in Perth, this makes flights into SYD, MEL and BNE harder to justify for me, as adding on the few thousand miles transcon to PER takes quite a chunk out of the 35k allowance. For me it might be better having a stopover in DPS and booking a cheap one way from there.
To clarify, there is no continent rule on a OWR.
Thanks kangol. Do you know or anyone know, if there is any benefit in having your long 'stopover' ie the 10 months or whatever, in your home city (like you suggested) or in an Asian hub like appaz's booking above in KUL
If you do it in your home city, you don't need to pay to book to get home in between. You can also save mileage for your longer legs. However, being from MEL (I assume), this isn't quite as short as it would be for me to pop to DPS, SIN or KUL. You could consider AKL as an interim point. Just keep in mind that you can't return to the city or country where your itinerary started until the end of your award.
