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.
