I'm still pretty confused in terms of what to do with this trip! Getting to Iceland seems so hard on an ex-UK xONEx ticket.
Thanks for the advice on DUB, christep. I didn't think about doing it that way. It looks like it's actually a little more (a couple hundred $$) to fly out of Ireland for the time I want to go (June) so it might just be easier for me to purchase a separate ticket from LGW-KEF (thanks for the advice on that, Guy Betsy and JohnAx) before starting my RTW. On the plus side, a trip to DUB might make for some good times.
I'm also hoping to visit DXB as part of this trip, so as far as i understand the rules, I think I would still be ok with DUB-(x)LON-KEF-(x)LON-DXB...
I do have some BA Executive Club miles available, so I could do what christep suggested and start ex-LGW and do LGW-KEF then use miles to get to DUB maybe, then go DUB-DXB... but that's too many stopovers in my continent of origin isn't it? It looks like the roundtrip for this award would be 25,000 miles, but I can't tell for sure because Iceland isn't listed yet, but if it is, does that make the 1 way 12,500 miles?
Thanks again everyone. It's nice to have so many pros around!
