Indeed.

DONE4 ex-ARN should be SEK 44690 (i.e. ca. USD 7070)
DONE4 ex-LHR should be GBP 4549 (i.e. ca. USD 9510) - conversions at IB rates

You save ca 2500 USD ex-ARN and avoid the problem of one international departure only from country of origin (this being a problem when country of origin = UK).

LHR has good fares for LONEx, not for DONEx.

When converting to CDA$ the LONEx from LHR is cheaper by $4000 CAD than the DONEx from ARN. So it is a personal decission whether it is worth it.

Trip is almost a year away so have to wait check closer to time to. book to find the best deal.

Cost tolerance (and feasibility) is of course a personal decision. That said, I advise people to take into account the tremendous potential mileage-earning benefits of a well-crafted business class RTW. In many cases, and depending on your FF program, you can leverage sufficient miles from the RTW to "pay" for a considerable amount of future travel.

As an example, an AA Plat member (easy to achieve using the Challenge) on a 60K mile RTW can book well over 130K "spendable" miles. An AA OW130C Oneworld award allows up to 20K "net" miles in business-class travel ("net" meaning only miles between stopovers are counted.) YYZ-LHR-SIN-HKG-YYZ is 19,700 miles - in other words, a second J-class RTW funded from one paid one. And so on.

An L class RTW will also earn miles, but not nearly as many, thereby reducing the leverage capability. But the cost spread between a LONE4 ex-UK and a DONE4 ex- somewhere else may be the equivalent of a second LONE4, so it's an individual call.

Yery good point Gardyloo & something I will consider.

That is why I am planning a year in advance as I am new to this & want to do it right.Some times what at first appears to be the cheapest, in the long run isn't cost effective & there is also comfort to be considered.

Sorry busman7, I might have misread your post.

I had the impression that you were considering an ex-LHR DONE4 as an alternative to an ex-North America LONE4. It's only beacuse of this that I said that an ex-LHR DONE4 is very expensive if compared to other European points of origin. It was not my intention to say that a DONE4 is better value for money than a LONE4. I am well aware that even the cheapest DONE4 is much more expensive than the average (or even the most expensive) LONE4...

In fact, all the OWE tickets I bought were LONEx since 4000 USD are a huge difference and my budget would not be happy

Sorry again if I misread.

In that case I misread too, because I also thought a comparison was being made between ex-NA economy and ex-LHR biz:

Sorry for the confusion SwissexLUG & viajero I comparing the ex-NA economy in CAD$ & the ex-LHR biz but forgot to convert GBP to CAD$ that made it look similar.

As for my post today what I was trying to say is that comparing the biz class ex-ARN & economy ex-LHR is a difference of $4000 CAD, on the extra points for biz class (which I haven't even looked into yet) it might be worth while or it might not.

Just weighing the options. Thanks for the input.
