OK, so I want a one-way upgrade for 20000 miles on the return of a transatlantic trip. Question is: what constitutes the "return":
Outward Day 1: DUB-AMS-ORD
(26 hours in ORD)
Outward Day 2: ORD-DTW-BNA
(a few days in BNA)
Inward Day 1: BNA-DTW-ORD
(14 hours in ORD)
Inward Day 2: ORD-DTW-LAX-AMS-DUB
3 possible interpretations:
1) BNA-DTW-ORD-DTW-LAX-AMS-DUB, on the ground that BNA is, in effect, the start of the return of my trip and that there is no stop-over between BNA and DUB (less than 24 hrs in ORD in this direction). Needless to say this is my favourite interpretation 
2) ORD-DTW-LAX-AMS-DUB, on the ground that all segments are flown continuously (I should get all 4 boarding passes in ORD) with no more than 2 hours between flights
3)LAX-AMS-DUB, on the ground that LAX is the point furthest away from origin (presumably, KL's FD interpretation 
) ?
Second question: can one upgrade on AMS-DUB (operated by EI)?

Nick,
Sorry for the late reply (just registered)
Interpretation 1 is correct, because BNA is the place where you spend most of your time.
Stopovers don't play a role in this case
