Upgrades by Oneworld partner airlines
I have top status with AA, DL, and UA, therefore with all 3 alliances. I get courtesy upgrades on a fairly regular basis from Skyteam and Star Alliance partner airlines on transoceanic flights. I have never, not even once, received a courtesy upgrade by any Oneworld partner airline. I'm curious - is this a familiar experience by other frequent fliers, or is it just my luck of the draw?
