Looking at my mileage summary for this year, all my domestic trips are mostly in S, T, or L, and the occasional V and W (and also one roundtrip on A for SFO-STL ). I have only done a trans-Pac in H for upgrade purposes and another trans-Atlantic in S this year. The rest of my trans-Pac/Atlantic are in other *A carriers. Looking forward to my first ever 1K welcome kit this December!
