Used to also be LAX-DFW but not sure if that is still operating, so that is another way -- to get real international F which is considerably better than international J on LA even if you get the coffin config. As for maximizing your mileage, you can add at least 5K to it by optimizing the US portion (something like JFK-SJU-LAX-DFW-ANC-DFW-LAX) but presumably you had reasons for visiting those specific cities in that sequence.
Thanks number 6. The only place I potentially need to go is IAH. However I always visit BOS when I am in the US (love that city)
Also comfort wise is a consideration. THe DFW-ANC is like 6 hours and one sector is a Red Eye on it!! As my schedule is tight (only around 2 weeks) so I don't want to come back like a wreck.
I was originally thinking instead of using 2 spare sectors (from the europe cont) on to the NA portion I might actually use it in Europe if they have these decent flights ie. FRA-MAD which earn reasonable miles with minimal effort and relatively comfortable.
In terms of MR value the LHR-DXB-LHR is already like 6000 miles in itself already (with cabin bonus it is around 6000). I don't think there are any european route that can beat that.
