DC was an amazing program, both in terms of low miles needed for redemption in miles+cash but also in terms of what you could do with the miles, one ways allowed, free stop over each way, a lot of flexibility on routing depending on which ICC agent you got..

I am considering a trip from the UK to Brazil this year and would quite like to do something which I believe you could generally get away with in DC, which was to route from Brazil to Europe via North America as a free stopover for the same amount of miles as Brazil to Europe direct. I now primarily use BAEC but it looks like doing this kind of thing is impossible with them without paying nearly double the miles.

Can anyone tell me what the best *A airline to do this kind of indirect routing without shelling out more miles? From a little bit of research it looks like US does allow this, but they do not allow one way bookings and they only allow one stopover in a roundtrip. Are there any other FF programs in *A that allow the same kind of flexible routing that DC allowed? Preferably ones that allow one way bookings and have low redemption rates.

Perhaps US is the best but I would like to confirm this and find out any alternatives before I decide which program to pursue.
