I've been reading old posts for quite a long time before writing this post.
I am looking to maximize my TP earning on a exDUB to Seattle that is coming in March.
So far, playing with itamatrix I was not able to get anything great or at least at a reasonable price.

This is what I was able to get so far from Itamatrix. (sorry, no URLs < 5 posts).
All in CW except DUB - LHR, sold by AA and operated by BA except SEA - ORD (AA).

DUB - LHR - SEA
SEA - ORD - LHR - DUB

£2134 and (20+140+40+140+40) 380 TP
Roughly £5.6/TP

What do you think about?
I am somehow flexible on both inbound/outbound, with the only requirement to be in Seattle from March 12th to 19th.
Is there anything better? I do not mind adding extra layover or stops as long as the provide extra TP or reduce the cost.

Thank you,
L
