I don't have the upgraded ticket yet. I am going DEN-FRA (747) and then FRA-DXB (346). I have a stopover in between to checkout frankfurt. I am currently in C. Assuming the F opens at T-14, I will have enough points to upgrade only one leg or the other to F. Would you say it's more worth it to upgrade the DEN-FRA flight, which will be in the 747 but will not get me FCT access, or to take F in the less impressive aircraft, but with the FCT on departure?
