Hi everyone, I'm new here and I've tried to find the answer to this question by searching, but I can't come up with anything. Hopefully someone here will have a better idea.

This summer I'm hoping to do my first RTW (an LONE4). I live in Canada, but would like to start from the UK as the LONE4 fares are much cheaper from there. One of the places I would really like to visit is Iceland. I see that BA is starting their LGW-REK-LGW flights soon, but I can't figure out how that will affect my trip. I was hoping to start ex-LON but is that even possible while still including Iceland? Will oneworld have to create a new exception to allow trips to REK?

Any help anyone can give me is very much appreciated!

Thanks,
