second vote for Condor A339 in J

Icelandair J on the 763 is nothing spectacular (2-1-2, big recliners similar to what domestic F featured ~2010), but perfectly adequate for the price point

if you’re positioning from ANC to the TATL gateway on a separate ticket, you’ll have to be careful about the connecting time; AS won’t check a bag thru to your TATL flight unless it’s on the same reservation

any redemption is likely to be in Main Cabin from ANC to any Lower 48 connecting point
